  • Windows Server 2003 IPSec Tunnel Connected, But Not Working (Possibly NAT/RRAS Related)

    - by Kevinoid
    Configuration I have setup a "raw" IPSec tunnel between a Windows Server 2003 (SBS) machine and a Netgear FVG318 according to the instructions in Microsoft KB816514. The configuration is as follows (using the same conventions as the article): NetA | SBS2003 | FVG318 | NetB 10.0.0.0/24 | 216.x.x.x | 69.y.y.y | 10.0.254.0/24 Both the Main Mode and Quick Mode Security Associations are successfully completed and appear in the IP Security Monitor. I am also able to ping the SBS2003 server on its private address from any computer on NetB. The Problem Any traffic sent from a computer on NetA to NetB, or from SBS2003 to NetB (excluding ICMP Ping responses), is sent out on the public network interface outside the IPSec tunnel (no encryption or header authentication, as if the tunnel were not there). Pings sent from a computer on NetB to a computer on NetA successfully reach computers on NetA, but the responses are silently discarded by SBS2003 (they do not go out in the clear and do not generate any encrypted traffic). Possible Solutions Incorrect Configuration I could have mistyped something, somewhere, or KB816514 could be incorrect in some way. I have tried very hard to eliminate the first option. Have re-created the configuration several times, tried tweaking and adjusting all the settings I could without success (most prevent the SA from being established). NAT/RRAS I have seen multiple posts elsewhere suggesting that this could be due to interaction between NAT and the IPSec filters. Possibly the NetA private addresses get rewritten to 216.x.x.x before being compared with the Quick Mode IPSec filters and don't get tunneled because of the mismatch. In fact, The Cable Guy article from June 2005 "TCP/IP Packet Processing Paths" suggests that this is the case, (see step 2 and 4 of the Transit Traffic path). If this is the case, is there a way to exclude NetA-NetB traffic from NAT? Any thoughts, ideas, suggestions, and/or comments are appreciated.

  • Update Grub on Squeeze - Kernel downgrade due VMware Server

    - by vodoo_boot
    I happen to run into various problems regarding grub and kernels. I don't really care about the kernel internas. All I want is VMware server in that dedicated root-server. 1.) What is a bzImage vs. vmlinuz? kaze:~# ls /boot/ System.map-2.6.32-5-amd64 bzImage-2.6.33.2 config-2.6.33.2 initrd.img-2.6.32-5-amd64 System.map-2.6.33.2 bzImage-2.6.35.6 config-2.6.35.6 vmlinuz-2.6.32-5-amd64 System.map-2.6.35.6 config-2.6.32-5-amd64 grub I updated my menu.lst (grub2): timeout 5 default 0 fallback 1 title 2.6.32.5 kernel (hd0,1)/boot/vmlinuz-2.6.32-5-amd64 root=/dev/sda2 panic=60 noapic acpi=off title 2.6.35.6 kernel (hd0,1)/boot//bzImage-2.6.35.6 root=/dev/sda2 panic=60 noapic acpi=off title 2.6.32.3 kernel (hd0,1)/boot//bzImage-2.6.33.2 root=/dev/sda2 panic=60 noapic acpi=off That doesn't do well... I think the vmlinuz file is missing initrd or so. Dunno. In fact I don't give too much about kernel boot voodoo as long as it works. update-grub(2) does not work. Does anybody know what magical trick there is to get the 2.6.32-5 booting? 2.) I thought t follow the Deban wiki.. I cannot get header-files for the installed 35.6 or 33.2 kernel in the repositories. I cannot build foreign headers because they will not match the running kernel. So how does one deal with that situtation? I'd prefer not to have to downgrade the kernel. Thanks for any answers!

  • Force delivery retry without restarting the SMTP Service on Windows Server 2008 R2

    - by Mathias R. Jessen
    I have a Windows Server 2008 R2 box hosting 3 virtual SMTP servers; vSMTP01, vSMTP02 and vSMTP03. The first two are configured to deliver all messages to dedicated smarthosts, while the last is set to just deliver the messages on its own. All other delivery settings are as default ----(vSMTP01)-----> {SMARTHST01} / ----Inbound mail--->---SMTPSRV01---[----(vSMTP02)-----> {SMARTHST02} \ ----(vSMTP03)-----> { Internet } Now I want to take SMARTHST01 out for maintenance, but I don't want to reject submissions to vSMTP01 while doing so, so I just let it continue running. When SMARTHST01 is no longer responding, vSMTP01 queues the messages and wait for the first retry interval to pass (15 minutes). So far so good. Let's say SMARTHST01 gets online again after 20 minutes. The first interval has passed, and I'll have to wait another 25 minutes for the second retry interval to pass. If I stop and start the SMTP Service (Services.msc - Simple Mail Transfer Protocol service - Stop), the server will retry all deliveries, but that would cause a service interruption for ALL virtual SMTP servers on the machine, which is highly undesirable. How can I manually force vSMTP01 to retry delivery of all queued messages without interrupting the service of vSMTP02 and vSMTP03?

  • Server 2008 email on Event variables

    - by Jeff Miles
    One of the new features of Server 2008 is the ability to attach a task to a specific event in the event logs. One of the actions available is to send an email through a SMTP server. This is working great, however it would be ideal if in the message body, the Event contents could be placed. I have tried using $eventdescription and %eventdescription%, but those are just shots in the dark. Any amount of googling produces no results. Does anyone know if this is possible? Update: Sparks' suggestion below is a step in the right direction I believe, however that method doesn't seem to work for all values. For example, I can pull the RecordID, Severity and Channel as shown, but I can't use the same method to retreive the EventID, or most importantly the description. Here's the raw XML from one event: [Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"] [System] [Provider Name="DFSR" /] [EventID Qualifiers="16384"]4412[/EventID] [Level]4[/Level] [Task]0[/Task] [Keywords]0x80000000000000[/Keywords] [TimeCreated SystemTime="2009-05-14T18:18:09.000Z" /] [EventRecordID]45692[/EventRecordID] [Channel]DFS Replication[/Channel] [Computer]servername.domain.com[/Computer] [Security /] [/System] [EventData] [Data]9046C3F4-843E-4A53-B941-4B20764072E5[/Data] [Data]D:\departments\Geomatics\Plan Quality\Data Processing\CG3533017 2009-05-13 KT FIXED[/Data] [Data]D:\departments[/Data] [Data]{26D5F604-E603-4F87-8EC3-DE9A945DA8FD}-v927199[/Data] [Data]Departments[/Data] [Data]domain.ca\files\departments[/Data] [Data]B8242CE2-F5EB-47DA-BA5B-1DD2F7EE3AB9[/Data] [Data]DFAA7A54-66CB-4C31-81A0-0F861382C32C[/Data] [Data]CG3533017 2009-05-13-{26D5F604-E603-4F87-8EC3-DE9A945DA8FD}-v927199[/Data] [/EventData] [/Event] I have tried using a ValueQuery for EventData, but it returns no data.

  • Windows module installer delaying login, server 2008 R2

    - by Kyle
    We updated our servers this weekend (windows updates), everything went fine except one of our terminal servers now hangs at login with the message, "waiting for windows modules installer." It eventually times out and leaves an event log message that the service has stopped unexpectedly. I have disabled the service and users can now login in a reasonable time frame. However we will need to re-enable the service in order to install further updates. I'm not sure where to start with this one, I'm an entry level admin and my colleagues are on vacation today, thank God this isn't a serious problem. Further details: -It affects all users. -The only third party software on the server is our ERP software and screwdrivers from Tricerat. -The only event log message is that the service has stopped unexpectedly. -The server manager screen does not display any information about roles it just says, "error". -The remote desktop roles all seem to be functioning properly, Remote app works as well as standard RDP. Let me know if there is any further details I can provide, I will be checking this frequently throughout the day.

  • SQL Server Replication Backup

    - by user18039
    Hi We have a new system that runs on SQL Server 2008 r2 64-bit. There is a primary on-line transactional processing (OLTP) database that accepts a high volume of updates from several thousand Point of Sale systems at stores around the country. In order to protect this vital function, I have decided to introduce a dedicated reporting database server - from which multiple users will run some pretty complex reports. I realise that there were a number of choices but I decided to use Transaction Replication as the mechanism for copying the data from the OLTP database to the new reporting database - one way replication. The solution has worked well in test. I'm now being asked what changes need to be made to the backup policy to cover the architectural changes. I have read pages such as MSDN:Strategies for Backing Up and Restoring Snapshot and Transactional Replication but I think these are overkill for my solution. In fact, my current thinking is that we simply need to continue making backups of the OLTP data and logs. If the Reporting db or any of the system replication (eg distribution) databases fail then it's no big deal - we can clear all down then re-create the replication. I realise that taking a complete snapshot of the OLTP would be time consuming (approx 5 hours) but I'd be more relaxed about this that trying to restore backups of the various data and log files in the correct sequence. My view is that the complex strategies set out in the MSDN article would only be the way to go for a more complex replication solution than I have, eg if there were multiple subscribers with 2-way replication. Would you agree? I'd be grateful for any advice. Many thanks, Rob.,

  • Experience with asymmetrical (non-identical hardware) SQL Server 2005 / Win 2003 cluster

    - by user24161
    I am reasonably good at dealing with SQL Server clusters; I am wondering if folks have experience, good or bad, using a mix of different models of servers from the same vendor in one SQL 2005 cluster. Suppose: I have one more powerful, more RAM, more shizzle box and one less powerful, less memory, less shizzle box bound together in a 2-node cluster. These would be HP DL380 and 580 machines (not that it should matter) I understand AND automate the process of managing memory for each SQL instance, so there's no memory contention when SQL instances fail over. Basically I am thinking a CLR proc will monitor the instances and self-regulate memory caps on each instance, so that they won't page or step on one another. I get the fact the instances might be slower and or under memory pressure if they share a "lesser" node, and that's OK. The business can deal with a slower instance in a server-problem scenario. Reasonable? Any "gotchas" to watch out for? More info 10/28: doing some experiments with a test cluster I find that reconfiguring max/min memory is OK PROVIDED the instance isn't already under memory pressure. If I torture the system with a huge query that demands a big chunk of RAM, and simultaneously adjust the memory allocation to a smaller value than what is being actively used, it's possible to run the instance out of memory and have it halt and restart itself (unhappy situation). Many ugly out-of-memory messages in the error log, crashing, burning... It's an extreme case, but good to know. Seems, then, that it would only be really safe to set this on startup of the instance, as in have a startup script that says "I am on node1, so my RAM settings are X or I am on node two, so they are Y," like this: http://sqlblog.com/blogs/aaron_bertrand... Update: I am testing a SQL Agent + PowerShell solution described in more detail here.

  • Windows Server 2008 R2 grinds to a screeching halt during file copy operations

    - by skolima
    When my Windows Server 2008 R2 machine is performing any large disk operations (copying 10GB files from one drive to another, copying similar file over network, merging HyperV snapshots, compressing large files), performance of the whole machine slows down terribly, everything becomes unresponsive. This is noticeable in any situation when the disk access is large enough not to fit in the cache. Are there any settings available for tuning this behaviour? I can accept slower file transfer if this would give me more responsiveness. System details: Dell Optiflex 960, Core 2 Quad Q9650, 8GB RAM, 2 SATA drives - 320GB (ST3320418AS) and 1TB (ST31000528AS), NCQ active on both, Intel 82564LM-3 Gigabit Ethernet, ATI HD 3450 graphics, Intel ICH10 bridge. We have multiple machines like this, every one is exhibiting the same behaviour. I though this was overkill for a workstation, apparently I was mistaken. Update: I guess I shouldn't have mentioned the HyperV at all. The above configuration is a standard workstation setup at the company I work for, this is not a server of any kind. I have at most 3 virtual machines working, and usually I'm the only person accessing them. Never the less, the slowdown occurs even when no VMs are running. On a Linux machine I'd simply ionice the copy process and I could forget about it, is there any way to manage IO priorities on Windows?

  • SQL Authority News – Secret Tool Box of Successful Bloggers: 52 Tips to Build a High Traffic Top Ranking Blog

    - by Pinal Dave
    When I started this blog, it was meant as a bookmark for myself for helpful tips and tricks.  Gradually, it grew into a blog that others were reading and commenting on.  While SQL and databases are my first love and the reason I started this blog, the side effect was that I discovered I loved writing.  I discovered a secret goal I didn’t even know I wanted – I wanted to become an author.  For a long time, writing this blog satisfied that urge.  Gradually, though, I wanted to see my name in print. 12th Book Over the past few years I have authored and co-authored a number of books – they are all based on my knowledge of SQL Server, and were meant to spread my years of experience into the world, to share what I have learned with my community.  I currently have elevan of these “manuals” available for sale.  As exciting as it was to see my name in print, I still felt that there was more I could do as an author. That is when I realized that I am more than just a SQL expert.  I have been writing this blog now for more than 10 years, and it grew from a personal bookmark to a thriving website with over 2 million views per month.  I thought to myself “I could write a book about how to create a successful blog!”  And that is exactly what I did.  I am extremely excited to share with all of you my new book – “Secret Toolbox of Successful Bloggers.” A Labor of Love This project has been a labor of love for me.  It started out as a series for this blog – I would post one article a week until I felt the topic had been covered.  I found that as I wrote, new topics kept popping up in my mind, and eventually this small blog series grew into a full book.  The blog series was large enough to last a whole year, so I definitely thought that it could be a full book.  Ideas on how to become a successful blogger were so frequent that, I will admit, I feel like there is so much I left out of this book.  I had a lot more to say than I originally thought! I am so excited to be sharing this book with all of you.  I am so passionate about this topic, and I feel like there are so many people who can benefit from this book.  I know that when I started this blog, I did not know what I was doing, and I would have loved a “helping hand” to tell what to do and what not to do.  If this book can act that way to any of my readers, I feel it is a success. Rules of Thumb If you are interested in the topic of becoming a blogger, as you read this book, keep in mind that it is suggestions only.  Blogging is so new to the world that while there are “rules of thumb” about what to do and what not to do, a map of steps (“first, do x, then do y”) is not going to work for every single blogger.  This book is meant to encourage new bloggers to put their content out there in the world, to be brave and create a community like the one I have here at SQL Authority.  I have gained so much from this community, I wanted to give something back, and this book is just one small part. I hope that everyone who reads this books finds at least one helpful tip, and that everyone can experience the joy of blogging.  That is the whole reason I wrote this book, and what I hope everyone takes away from it. Where Can You Get It? You can get the book from following URL: Kindle eBook | Print Book Reference: Pinal Dave (http://blog.SQLAuthority.com)Filed under: About Me, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority Author Visit, T SQL

  • Series On Embedded Development (Part 2) - Build-Time Optionality

    - by user12612705
    In this entry on embedded development, I'm going to discuss build-time optionality (BTO). BTO is the ability to subset your software at build-time so you only use what is needed. BTO typically pertains more to software providers rather then developers of final products. For example, software providers ship source products, frameworks or platforms which are used by developers to build other products. If you provide a source product, you probably don't have to do anything to support BTO as the developers using your source will only use the source they need to build their product. If you provide a framework, then there are some things you can do to support BTO. Say you provide a Java framework which supports audio and video. If you provide this framework in a single JAR, then developers who only want audio are forced to ship their product with the video portion of your framework even though they aren't using it. In this case, support providing the framework in separate JARs...break the framework into an audio JAR and a video JAR and let the users of your framework decide which JARs to include in their product. Sometimes this is as simple as packaging, but if, for example, the video functionality is dependent on the audio functionality, it may require coding work to cleanly separate the two. BTO can also work at install-time, and this is sometimes overlooked. Let's say your building a phone application which can use Near Field Communications (NFC) if it's available on the phone, but it doesn't require NFC to work. Typically you'd write one app for all phones (saving you time)...both those that have NFC and those that don't, and just use NFC if it's there. However, for better efficiency, you can detect at install-time if the phone supports NFC and not install the NFC portion of your app if the phone doesn't support NFC. This requires that you write the app so it can run without the optional NFC code and that you write your install app so it can detect NFC and do the right thing at install-time. Supporting install-time optionality will save persistent footprint on the phone, something your customers will appreciate, your app "neighbors" will appreciate, and that you'll appreciate when they save static footprint for you. In the next article, I'll talk about runtime optionality.

  • PPTP connection fails with errors 800/806

    - by Mark S. Rasmussen
    I've got a client (Server 2008 R2) that won't connect to our production environment PPTP VPN server (Server 2003, running RRAS). The server is behind a firewall that has TCP1723 open as well as GRE. Other clients at our office are able to connect just fine. Our office is behind a Juniper SSG5-Serial firewall, but all outgoing traffic is allowed, and multiple other clients are able to connect to VPN servers without issues. I've also setup a completely different VPN server on another network outside of our office. The functioning clients connect just fine - the Server 2008 R2 machine doesn't. Thus it's definitely a problem with this machine in particular. I've rebooted it. I've disabled the firewall, no dice on either. I've run PPTPSRV and PPTPCLNT on the server/client and they're able to communicate perfectly - indicating there's no problem using neither TCP1723 nor GRE. The Server 2008 R2 machine is also running as a VPN server itself (incoming connection) and that's working perfectly. We have the issues no matter if there are active incoming connections or not. I'm not sure what my next debugging step would be; any suggestions? EDIT: The event log on the server has the following warning from RasMan: A connection between the VPN server and the VPN client xxx.xxx.xxx.xxx has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets. Obviously this points to GRE being a potential problem. But seeing as I have other clients connectiong without problems, as well as PPTPSRV and PPTPCLNT being able to communicate, I'm suspecting this might be a red herring. EDIT: Here are the anonymized events logged by the client in chronological order: CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY has started dialing a VPN connection using a per-user connection profile named ZZZ.

CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY dialed a connection named ZZZ which has failed. The error code returned on failure is 806. Running Wireshark on the client shows it trying and retrying to send a "71 Configuration Request" While the server shows the incoming client requests, but apparently without replying: Given that this is GRE traffic, I think rules out the GRE traffic being blocked. Question is, why doesn't the server reply? This is the Configuration Request the server receives from the non functioning client (meaning no response is sent to the client request): And this is the Configuration Request the server receives from the working client: To me they seem identical, except for differing keys and magic numbers, and the fact that one client receives a response while the other doesn't.

  • High CPU usage - symptoms moving from server to server after bouncing

    - by grt3kl
    First off, I apologize if I didn't include enough information to properly troubleshoot this issue. This sort of thing isn't my specialty, so it is a learning process. If there's something I need to provide, please let me know and I'll be happy to do what I can. The images associated with my question are at the bottom of this post. We are dealing with a clustered environment of four WebLogic 9.2 Java application servers. The cluster utilizes a round-robin load algorithm. Other details include: Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04) BEA JRockit(R) (build R27.4.0-90_CR352234-91983-1.5.0_12-20071115-1605-linux-x86_64, compiled mode) Basically, I started looking at the servers' performance because our customers are seeing lots of lag at various times of the day. Our servers should easily handle the loads they are given, so it's not clear what's going on. Using HP Performance Manager, I generated some graphs that indicate that the CPU usage is completely out of whack. It seems that, at any given point, one or more of the servers has a CPU utilization of over 50%. I know this isn't particularly high, but I would say it is a red flag based on the CPU utilization of the other servers in the WebLogic cluster. Interesting things to note: The high CPU utilization was occurring only on server02 for several weeks. The server crashed (extremely rare; we are not sure if it's related to this) and upon starting it back up, the CPU utilization was normal on all 4 servers. We restarted all 4 managed servers and the application server (on server01) yesterday, on 2/28. As you can see, server03 and server04 picked up the behavior that was seen on server02 before. The CPU utilization is a Java process owned by the application user (appown). The number of transactions is consistent across all servers. It doesn't seem like any one server is actually handling more than another. If anyone has any ideas or can at least point me in the right direction, that would be great. Again, please let me know if there is any additional information I should post. Thanks!
