  • SCOM, Server 2008 and SQL Server 2008

    - by Jacques
    Hi there, I'm trying to setup SCOM(System Center Operations Manager 2007 (SCOM) – Platform Monitoring) on my Server 2008 machine using SQL Server 2008 running on the same machine. When I check my prerequisites I get problem on SQL and Active Directory components. (I'm running SQL server 2008 and Server 2008 with active directory not installed) Errors: 1.Microsoft SQL Server 2005 Service Pack 1 required. Details: SQL Server 2005 SP1 is the next version of SQL Server. SQL Server 2005 Enterprise Edition, is a complete data and analysis platform for large mission-critical business applications. The link provided in the resolution column is a trial version of the product and is not supported by the Microsoft SQL Server team In order to install active directory needs to be present. Details:Setup failed to verify the presence of Active Directory for this server. I've got a couple of questions I need answering, hope someone can help. Do I need to install Active Directory for SCOM to work? Can I run SCOM with an SQL 2008 Database? How do I get pass these problems?

  • Web server connection to SQL Server: Response Packet [Malformed Packet]

    - by John Murdoch
    I am seeing very, very sluggish performance between my web server (which handles HTTP web services connections) and a separate server running Microsoft SQL Server 2008. I have been capturing packet traffic on the web server trying to understand why things are running so slowly. I am using Wireshark to capture the packet traffic. The apparent problem is that the web server is sending TDS packets to the data server--each packet followed by a response from the data server with Response Packet [Malformed Packet] in the Info field. The packet sent from the web server appears to have an invalid checksum. Has anyone seen this type of problem before? Any ideas?

  • Can't restore backup from SQL Server 2008 R2 to SQL Server 2005 or 2008

    - by Erick
    Hi everyone, I'm trying to get a backup from SQL Server 2008 R2 restored to SQL Server 2008, but when we try to do the restore we get this: The database was backed up on a server running version 10.50.1092. That version is incompatible with this server, which is running version 10.00.2531. Either restore the database on a server that supports the backup, or use a backup that is compatible with this server. I can use the script wizard to generate a script, but that takes over an hour to run. I also tried just exporting the data from server to server, but it had issues with the primary keys/identity columns. I will be running into this issue with several other clients so any help you could offer about how to get around this would be great. Thanks for your help!

  • SQL Server 2008: Can't connect to remote server via management studio but can telnet in fine

    - by WarpKid
    Hi, I am in the process of trying to configure SQL Server 2008 to accept remote connections. I have been through all the documentation I can find and yet when I attempt to connect through management studio I get an error stating that the server could not be found. Interestingly I can connect through telnet to the remote server via the port that sql server is listening on. In the SQL Server logs I can see the connection attempt. So SQL Server is up and running and listening on the correct port - no firewall blocking it. It would appear that by default SQL Server is listening on port 50314 by default but management studio attempts to connect on port 1433.Weird. Server Management Studio = no dice. Anyone got any ideas? Server is set to allow remote connections - TCP IP is enabled, firewall is off. Thanks UPDATE FOR TO CLEAR THINGS UP A BIT We are seeing the connection attempt when we telnet in on port 50314 in the sql server logs. When we login through management studio we see it attempting connection on port 1433. There is no sign of this connection attempt in the logs.

  • SQL Server 2008 R2 upgrade fails on upgrade rule check

    - by Tim
    I'm trying to upgrade an evaluation instance of SQL Server 2008 to a fully licensed instance of SQL Server 2008 R2. I made it most of the way through the installer, but I'm getting stopped at the Upgrade Rules page - the SQL Server Analysis Services Upgrade Service Functional Check is failing. The specific error I get: Rule "SQL Server Analysis Services Upgrade Service Functional Check" failed. The current instance of the SQL Server Analysis Services service cannot be upgraded because the Analysis Services service is disabled or not online. Please start the service and then run the upgrade rules check again. Simple enough - just need to start the service. Here's where it gets troublesome. When I open Services and go to start the SQL Server Analysis Services (MSSQLSERVER) service, it provides me the following message: The SQL Server Analysis Services (MSSQLSERVER) service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs. Trying from the command line as Administrator yields: PS C:\Windows\System32 net start MSSQLServerOLAPService The SQL Server Analysis Services (MSSQLSERVER) service is starting... The SQL Server Analysis Services (MSSQLSERVER) service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. I've tried changing the logon setting of this service to Administrator, a user with admin privileges, and both the Local System and Network Service accounts - nothing works. In addition, when I look at the service through the SQL Server Configuration Manager (also run as Administrator), attempting to change the logon setting for the service results in the message: The server threw an exception. [0x80010105] I have no need for analysis services themselves - all I need is for this one service to be running long enough to do the R2 upgrade, then it can shut down again. Any thoughts on how to get the Analysis Services service running? Update: Checking the event log, I found an error logged to the Application log from the MSSQLServerOLAPService. It has event ID 0, task category (289), and says: The service cannot be started: XML parsing failed at line 1, column 4: Unrecognized input signature.

  • Authenticating Linked Servers - SQL Server 8 to SQL Server 10

    - by jp2code
    We have an old SQL Server 2000 database that has to be kept because it is needed on our manufacturing machines. It also maintains our employee records, since they are needed on these machines for employee logins. We also have a newer SQL Server 10 database (I think this is 2008, but I'm not sure) that we are using for newer development. I have recently learned (i.e. today) that I can link the two servers. This would allow me to access the employee tables in the newer server. Following the SF post SQL Server to SQL Server Linked Server Setup, I tried adding the link. In our SQL Server 2000 machine, I got this error: Similarly, on our SQL Server 10 machine, I got this error: The messages, though worded different, probably say the same thing: I need to authenticate, somehow. We have an Active Directory, but it is on yet another server. What, exactly, should be done here? A guy HERE<< said to check the Security settings, but did not say what else to do. Both servers are set to SQL Server and Windows Authentication mode. Now what?

  • SQL Server Management Studio Express 2005 has no Configuration Manager

    - by brohjoe
    Where is the configuration manager for SQL Express 2005? I need to configure SQL Server for TCP/IP but there is no configuration manager with the package. I see SQL Server Database Publishing Wizard, I see SQL Server Migration Assistant for Access, but no Configuration Manager. According to the MSDN, there should be one. I've even looked online for a download of the Configuration Manager for SQL Server 2005, but could not find one. Did I miss something in the download or should I just scrap SQL Server Express and download the full-blown SQL Server for Developers?

  • SQL SERVER – Determine if SSRS 2012 is Installed on your SQL Server

    - by Pinal Dave
    This example is from the Beginning SSRS by Kathi Kellenberger. Supporting files are available with a free download from the www.Joes2Pros.com web site. Determine if SSRS 2012 is Installed on your SQL Server You may already have SSRS, or you may need to install it. Before doing any installation it makes sense to know where you are now. If you happened to install SQL Server with all features, you have the tools you need. There are two tools you need: SQL Server Data Tools and Reporting Services installed in Native Mode. To find out if SQL Server Data Tools (SSDT) is installed, click the Start button, go to All Programs, and expand SQL Server 2012. Look for SQL Server Data Tools   Now, let’s check to see if SQL Server Reporting Services is installed. Click the Start > All Programs > SQL Server 2012 > Configuration Tools > SQL > Server Configuration Manager   Once Configuration Manager is running, select SQL Server Services. Look for SQL Server Reporting Services in the list of services installed. If you have both SQL Server Reporting Services service and SQL Server Developer tools installed, you will not have to install them again. You may have SQL Server installed, but are missing the Data Tools or the SSRS service or both. In tomorrow blog post we will go over how to install based on where you are now.   Tomorrow’s Post Tomorrow’s blog post will show how to install and configure SSRS. If you want to learn SSRS in easy to simple words – I strongly recommend you to get Beginning SSRS book from Joes 2 Pros.

  • How to sysprep SQL Server Express?

    - by Jim
    We plan to deploy Hyper-V VHD with Windows Server 2008 R2 and SQL Server 2012 Express installed to multiple hosts. From my understanding, the correct way to do this is to install SQL Server in prepartion mode, sysprep Windows, then complete SQL Server installation when the VHD is deployed. I mostly followed the process in this blog post: http://sethusrinivasan.com/category/sysprep/ However, after the VHD is deployed, I'm unable to complete the SQL Server installation. It keeps saying "Upgrade matrix is incorrect". It seems that it's trying to upgrade itself to Enterprise edition (I was asked for product key during install, but I skipped it). Could anyone share their experience in deploying VHDs with SQL Server (we're fine with either SQL Server 2008 R2 or 2012)? I think the source of my issue is because I can't select "Express Edition" when entering the product key at the completion stage, so the installation is trying to do an upgrade to Enterprise Edition. I have no idea why the drop down list is empty.

  • SQL SERVER – Guest Posts – Feodor Georgiev – The Context of Our Database Environment – Going Beyond the Internal SQL Server Waits – Wait Type – Day 21 of 28

    - by pinaldave
    This guest post is submitted by Feodor. Feodor Georgiev is a SQL Server database specialist with extensive experience of thinking both within and outside the box. He has wide experience of different systems and solutions in the fields of architecture, scalability, performance, etc. Feodor has experience with SQL Server 2000 and later versions, and is certified in SQL Server 2008. In this article Feodor explains the server-client-server process, and concentrated on the mutual waits between client and SQL Server. This is essential in grasping the concept of waits in a ‘global’ application plan. Recently I was asked to write a blog post about the wait statistics in SQL Server and since I had been thinking about writing it for quite some time now, here it is. It is a wide-spread idea that the wait statistics in SQL Server will tell you everything about your performance. Well, almost. Or should I say – barely. The reason for this is that SQL Server is always a part of a bigger system – there are always other players in the game: whether it is a client application, web service, any other kind of data import/export process and so on. In short, the SQL Server surroundings look like this: This means that SQL Server, aside from its internal waits, also depends on external waits and settings. As we can see in the picture above, SQL Server needs to have an interface in order to communicate with the surrounding clients over the network. For this communication, SQL Server uses protocol interfaces. I will not go into detail about which protocols are best, but you can read this article. Also, review the information about the TDS (Tabular data stream). As we all know, our system is only as fast as its slowest component. This means that when we look at our environment as a whole, the SQL Server might be a victim of external pressure, no matter how well we have tuned our database server performance. Let’s dive into an example: let’s say that we have a web server, hosting a web application which is using data from our SQL Server, hosted on another server. The network card of the web server for some reason is malfunctioning (think of a hardware failure, driver failure, or just improper setup) and does not send/receive data faster than 10Mbs. On the other end, our SQL Server will not be able to send/receive data at a faster rate either. This means that the application users will notify the support team and will say: “My data is coming very slow.” Now, let’s move on to a bit more exciting example: imagine that there is a similar setup as the example above – one web server and one database server, and the application is not using any stored procedure calls, but instead for every user request the application is sending 80kb query over the network to the SQL Server. (I really thought this does not happen in real life until I saw it one day.) So, what happens in this case? To make things worse, let’s say that the 80kb query text is submitted from the application to the SQL Server at least 100 times per minute, and as often as 300 times per minute in peak times. Here is what happens: in order for this query to reach the SQL Server, it will have to be broken into a of number network packets (according to the packet size settings) – and will travel over the network. On the other side, our SQL Server network card will receive the packets, will pass them to our network layer, the packets will get assembled, and eventually SQL Server will start processing the query – parsing, allegorizing, generating the query execution plan and so on. So far, we have already had a serious network overhead by waiting for the packets to reach our Database Engine. There will certainly be some processing overhead – until the database engine deals with the 80kb query and its 20 subqueries. The waits you see in the DMVs are actually collected from the point the query reaches the SQL Server and the packets are assembled. Let’s say that our query is processed and it finally returns 15000 rows. These rows have a certain size as well, depending on the data types returned. This means that the data will have converted to packages (depending on the network size package settings) and will have to reach the application server. There will also be waits, however, this time you will be able to see a wait type in the DMVs called ASYNC_NETWORK_IO. What this wait type indicates is that the client is not consuming the data fast enough and the network buffers are filling up. Recently Pinal Dave posted a blog on Client Statistics. What Client Statistics does is captures the physical flow characteristics of the query between the client(Management Studio, in this case) and the server and back to the client. As you see in the image, there are three categories: Query Profile Statistics, Network Statistics and Time Statistics. Number of server roundtrips–a roundtrip consists of a request sent to the server and a reply from the server to the client. For example, if your query has three select statements, and they are separated by ‘GO’ command, then there will be three different roundtrips. TDS Packets sent from the client – TDS (tabular data stream) is the language which SQL Server speaks, and in order for applications to communicate with SQL Server, they need to pack the requests in TDS packets. TDS Packets sent from the client is the number of packets sent from the client; in case the request is large, then it may need more buffers, and eventually might even need more server roundtrips. TDS packets received from server –is the TDS packets sent by the server to the client during the query execution. Bytes sent from client – is the volume of the data set to our SQL Server, measured in bytes; i.e. how big of a query we have sent to the SQL Server. This is why it is best to use stored procedures, since the reusable code (which already exists as an object in the SQL Server) will only be called as a name of procedure + parameters, and this will minimize the network pressure. Bytes received from server – is the amount of data the SQL Server has sent to the client, measured in bytes. Depending on the number of rows and the datatypes involved, this number will vary. But still, think about the network load when you request data from SQL Server. Client processing time – is the amount of time spent in milliseconds between the first received response packet and the last received response packet by the client. Wait time on server replies – is the time in milliseconds between the last request packet which left the client and the first response packet which came back from the server to the client. Total execution time – is the sum of client processing time and wait time on server replies (the SQL Server internal processing time) Here is an illustration of the Client-server communication model which should help you understand the mutual waits in a client-server environment. Keep in mind that a query with a large ‘wait time on server replies’ means the server took a long time to produce the very first row. This is usual on queries that have operators that need the entire sub-query to evaluate before they proceed (for example, sort and top operators). However, a query with a very short ‘wait time on server replies’ means that the query was able to return the first row fast. However a long ‘client processing time’ does not necessarily imply the client spent a lot of time processing and the server was blocked waiting on the client. It can simply mean that the server continued to return rows from the result and this is how long it took until the very last row was returned. The bottom line is that developers and DBAs should work together and think carefully of the resource utilization in the client-server environment. From experience I can say that so far I have seen only cases when the application developers and the Database developers are on their own and do not ask questions about the other party’s world. I would recommend using the Client Statistics tool during new development to track the performance of the queries, and also to find a synchronous way of utilizing resources between the clientserverclient. Here is another example: think about similar setup as above, but add another server to the game. Let’s say that we keep our media on a separate server, and together with the data from our SQL Server we need to display some images on the webpage requested by our user. No matter how simple or complicated the logic to get the images is, if the images are 500kb each our users will get the page slowly and they will still think that there is something wrong with our data. Anyway, I don’t mean to get carried away too far from SQL Server. Instead, what I would like to say is that DBAs should also be aware of ‘the big picture’. I wrote a blog post a while back on this topic, and if you are interested, you can read it here about the big picture. And finally, here are some guidelines for monitoring the network performance and improving it: Run a trace and outline all queries that return more than 1000 rows (in Profiler you can actually filter and sort the captured trace by number of returned rows). This is not a set number; it is more of a guideline. The general thought is that no application user can consume that many rows at once. Ask yourself and your fellow-developers: ‘why?’. Monitor your network counters in Perfmon: Network Interface:Output queue length, Redirector:Network errors/sec, TCPv4: Segments retransmitted/sec and so on. Make sure to establish a good friendship with your network administrator (buy them coffee, for example J ) and get into a conversation about the network settings. Have them explain to you how the network cards are setup – are they standalone, are they ‘teamed’, what are the settings – full duplex and so on. Find some time to read a bit about networking. In this short blog post I hope I have turned your attention to ‘the big picture’ and the fact that there are other factors affecting our SQL Server, aside from its internal workings. As a further reading I would still highly recommend the Wait Stats series on this blog, also I would recommend you have the coffee break conversation with your network admin as soon as possible. This guest post is written by Feodor Georgiev. Read all the post in the Wait Types and Queue series.

  • Replication: SQL Server 2008 Publisher with SQL Server Express 2005 Subscriber

    - by Jeremy
    Here is the setup: SQL Server 2008 Enterprise Server with a Merge Publication. SQL Server 2005 Express with pull subscription. There is no web or ftp setup. This is direct merge replication. Using the RMO objects from C#, I get a "class cannot be found." COM Error when accessing the MergePullSubscription.SynchronizationAgent property. I've tried with both the 2008 RMO dll's (version 10 dll's) and the 2005 RMO dll's (version 9 dll's).

  • SQL Server Master class winner

    - by Testas
     The winner of the SQL Server MasterClass competition courtesy of the UK SQL Server User Group and SQL Server Magazine!    Steve Hindmarsh     There is still time to register for the seminar yourself at:  www.regonline.co.uk/kimtrippsql     More information about the seminar     Where: Radisson Edwardian Heathrow Hotel, London  When: Thursday 17th June 2010  This one-day MasterClass will focus on many of the top issues companies face when implementing and maintaining a SQL Server-based solution. In the case where a company has no dedicated DBA, IT managers sometimes struggle to keep the data tier performing well and the data available. This can be especially troublesome when the development team is unfamiliar with the affect application design choices have on database performance. The Microsoft SQL Server MasterClass 2010 is presented by Paul S. Randal and Kimberly L. Tripp, two of the most experienced and respected people in the SQL Server world. Together they have over 30 years combined experience working with SQL Server in the field, and on the SQL Server product team itself. This is a unique opportunity to hear them present at a UK event which will: Debunk many of the ingrained misconceptions around SQL Server's behaviour    Show you disaster recovery techniques critical to preserving your company's life-blood - the data    Explain how a common application design pattern can wreak havoc in the database Walk through the top-10 points to follow around operations and maintenance for a well-performing and available data tier! Please Note: Agenda may be subject to change  Sessions Abstracts  KEYNOTE: Bridging the Gap Between Development and Production    Applications are commonly developed with little regard for how design choices will affect performance in production. This is often because developers don't realize the implications of their design on how SQL Server will be able to handle a high workload (e.g. blocking, fragmentation) and/or because there's no full-time trained DBA that can recognize production problems and help educate developers. The keynote sets the stage for the rest of the day. Discussing some of the issues that can arise, explaining how some can be avoided and highlighting some of the features in SQL 2008 that can help developers and DBAs make better use of SQL Server, and troubleshoot when things go wrong.   SESSION ONE: SQL Server Mythbusters  It's amazing how many myths and misconceptions have sprung up and persisted over the years about SQL Server - after many years helping people out on forums, newsgroups, and customer engagements, Paul and Kimberly have heard it all. Are there really non-logged operations? Can interrupting shrinks or rebuilds cause corruption? Can you override the server's MAXDOP setting? Will the server always do a table-scan to get a row count? Many myths lead to poor design choices and inappropriate maintenance practices so these are just a few of many, many myths that Paul and Kimberly will debunk in this fast-paced session on how SQL Server operates and should be managed and maintained.   SESSION TWO: Database Recovery Techniques Demo-Fest  Even if a company has a disaster recovery strategy in place, they need to practice to make sure that the plan will work when a disaster does strike. In this fast-paced demo session Paul and Kimberly will repeatedly do nasty things to databases and then show how they are recovered - demonstrating many techniques that can be used in production for disaster recovery. Not for the faint-hearted!   SESSION THREE: GUIDs: Use, Abuse, and How To Move Forward   Since the addition of the GUID (Microsoft’s implementation of the UUID), my life as a consultant and "tuner" has been busy. I’ve seen databases designed with GUID keys run fairly well with small workloads but completely fall over and fail because they just cannot scale. And, I know why GUIDs are chosen - it simplifies the handling of parent/child rows in your batches so you can reduce round-trips or avoid dealing with identity values. And, yes, sometimes it's even for distributed databases and/or security that GUIDs are chosen. I'm not entirely against ever using a GUID but overusing and abusing GUIDs just has to be stopped! Please, please, please let me give you better solutions and explanations on how to deal with your parent/child rows, round-trips and clustering keys!   SESSION 4: Essential Database Maintenance  In this session, Paul and Kimberly will run you through their top-ten database maintenance recommendations, with a lot of tips and tricks along the way. These are distilled from almost 30 years combined experience working with SQL Server customers and are geared towards making your databases more performant, more available, and more easily managed (to save you time!). Everything in this session will be practical and applicable to a wide variety of databases. Topics covered include: backups, shrinks, fragmentation, statistics, and much more! Focus will be on 2005 but we'll explain some of the key differences for 2000 and 2008 as well. Speaker Biographies     Kimberley L. Tripp Paul and Kimberly are a husband-and-wife team who own and run SQLskills.com, a world-renowned SQL Server consulting and training company. They are both SQL Server MVPs and Microsoft Regional Directors, with over 30 years of combined experience on SQL Server. Paul worked on the SQL Server team for nine years in development and management roles, writing many of the DBCC commands, and ultimately with responsibility for core Storage Engine for SQL Server 2008. Paul writes extensively on his blog (SQLskills.com/blogs/Paul) and for TechNet Magazine, for which he is also a Contributing Editor. Kimberly worked on the SQL Server team in the early 1990s as a tester and writer before leaving to found SQLskills and embrace her passion for teaching and consulting. Kimberly has been a staple at worldwide conferences since she first presented at TechEd in 1996, and she blogs at SQLskills.com/blogs/Kimberly. They have written Microsoft whitepapers and books for SQL Server 2000, 2005 and 2008, and are regular, top-rated presenters worldwide on database maintenance, high availability, disaster recovery, performance tuning, and SQL Server internals. Together they teach the SQL MCM certification and throughout Microsoft.In their spare time, they like to find frogfish in remote corners of the world.   Speaker Testimonials  "To call them good trainers is an epic understatement. They know how to deliver technical material in ways that illustrate it well. I had to stop Paul at one point and ask him how long it took to build a particular slide because the animations were so good at conveying a hard-to-describe process." "These are not beginner presenters, and they put an extreme amount of preparation and attention to detail into everything that they do. Completely, utterly professional." "When it comes to the instructors themselves, Kimberly and Paul simply have no equal. Not only are they both ultimate authorities, but they have endless enthusiasm about the material, and spot on delivery. If either ever got tired they never showed it, even after going all day and all week. We witnessed countless demos over the course of the week, some extremely involved, multi-step processes, and I can’t recall one that didn’t go the way it was supposed to." "You might think that with this extreme level of skill comes extreme levels of egotism and lack of patience. Nothing could be further from the truth. ... They simply know how to teach, and are approachable, humble, and patient." "The experience Paul and Kimberly have had with real live customers yields a lot more information and things to watch out for than you'd ever get from documentation alone." “Kimberly, I just wanted to send you an email to let you know how awesome you are! I have applied some of your indexing strategies to our website’s homegrown CMS and we are experiencing a significant performance increase. WOW....amazing tips delivered in an exciting way!  Thanks again”

  • J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

    - by Mike
    J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

  • Intermittent Disconnection of Client Computers from Domain Server

    - by dilip nagle
    The Background: I have Windows 2008 server Enterprise Version with 25 user cal licences. It has a domain and all users and a network shared HP printer in it. The Server has two network cards and both these cards as well as all client machines are on IP addressing scheme of 192.168.1.* with subnetmask 255.255.255.0. Of the two network cards viz. 192.168.1.231 and 192.168.1.233, only 192.168.1.231 is registered with DNS. In 192.168.1.233(i.e. 2nd network card) has default getway as 192.168.1.231 and dns address as 192.168.1.231. The Server has three hard disks with capacities as 500gb, 500gb and 1TB and are partitioned as (C,D,E), (F,G) and (K) with partition K having all user data into various Shared Folders. Each of these folders(On Partition K), are mapped onto each user's computer as per the right of access given to them. The Problem: The Server was installed about 6 months ago and till date not even once, the Server has Hung or has given any problem. All the Clients computers are able to run the web based software from their computers via ip address, e.g. http://192.168.1.231/webERP/default.aspx. However, occassionally, when any client computer tries to browse network mappings, it hangs. Again, there is no fixed pattern. This may happen after running smoothly for say 3 days. On each Client's machine, the network settings are as follows: IP Address: 192.168.1.* where * is 1,2,3 .... Sunnetmask: 255.255.255.0 defauly getway: 192.168.1.231 Which is a server card and DNS address. preferred DNS Server: 192.168.1.231 In Advanced Tab under Wins: LMHostLookup is Unticked and default is radio buttoned. Ideally, I would have loved to have Disabled NETBIOS over TCP/IP but some network printers do not get accessed if this option is enabled(ie. Radio Buttoned). Bacause Disabling Netbios will drastically reduce traffic of NETBIOS broadcasting to all the computers on the net to do naming resolution. On Server, I have WINs Running which I have Scavanged Records, verified Database Integrity etc, removed Tombstoned Records etc. The Critical Errors shown only once a day when the server is statred are 4224(WINS) and 12923 - Server Licencing failed to Update DNS Record. I fail to understand as why do client machines HANG when they try to browse mapped network shared folders on K Drive. Kindly Advice

  • Free tools for analyzing client-server communication issues

    - by roberto
    Hi, we have some issues with a client-server based application and we would like to better understand client-server communication without going to the software company that sold the application. At least we would like to perform the analysis in parallel. Can you suggest to me a dummy proof application that we can easily get and install to analyze client-server traffic? Many thanks!

  • Idea to develop a caching server between IIS and SQL Server

    - by John
    I work on a few high traffic websites that all share the same database and that are all heavily database driven. Our SQL server is max-ed out and, although we have already implemented many changes that have helped but the server is still working too hard. We employ some caching in our website but the type of queries we use negate using SQL dependency caching. We tried SQL replication to try and kind of load balance but that didn't prove very successful because the replication process is quite demanding on the servers too and it needed to be done frequently as it is important that data is up to date. We do use a Varnish web caching server (Linux based) to take a bit of the load off both the web and database server but as a lot of the sites are customised based on the user we can only do so much. Anyway, the reason for this question... Varnish gave me an idea for a possible application that might help in this situation. Just like Varnish sits between a web browser and the web server and caches response from the web server, I was wondering about the possibility of creating something that sits between the web server and the database server. Imagine that all SQL queries go through this SQL caching server. If it's a first time query then it will get recorded, and the result requested from the SQL server and stored locally on the cache server. If it's a repeat request within a set time then the result gets retrieved from the local copy without the query being sent to the SQL server. The caching server could also take advantage of SQL dependency caching notifications. This seems like a good idea in theory. There's still the same amount of data moving back and forward from the web server, but the SQL server is relieved of the work of processing the repeat queries. I wonder about how difficult it would be to build a service that sort of emulates requests and responses from SQL server, whether SQL server's own caching is doing enough of this already that this wouldn't be a benefit, or even if someone has done this before and I haven't found it? I would welcome any feedback or any references to any relevant projects.

  • Filezilla FTP Server - Security Implications of its usage on Windos Server 2003

    - by Brian Webster
    I'm running Filezilla server on my dedicated windows 2003 server. It uses its own user-access control system. The Filezilla server service itself is running under the System user. When I setup users within the FTP Server Administrator Interface, I do not need to setup equivalent users, or adjust permissions on folders to allow users to login. Example: I setup TestFTP user with password 'p' I set the home directoy of TestFTP user to be e:/website I verify that e:/website only has permission for the System and Admin accounts (right click - security in windows explorer) TestFTP is able to login to the server just fine. I'm OK with this (perhaps due to ignorance?). Is it generally frounded upon to utilize a FTP Server such as FileZilla Server that bypasses the built-in UAC in this method? If I wasn't clear enough, please let me know.

  • Design pattern for client/server sessions?

    - by nonot1
    Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.
