• How much effort is SQL Server 2008 Administration?

  - by Adrian Grigore

  Hi, I am looking for a suitable hosting environment for an ASP.NET MVC application. One of the options I have is renting a Hyper-V server and installing my license of SQL Server 2008 on it. I'm a bit wary of shared hosting since the one I have tried so far did not seem to have very consistent performance. One potential problem is that I would have I do not not know much about SQL Server administration, so I am not sure if this is a good option. I've been running a failover cluster of two linux dedicated servers for over 5 years now and MySQL never gave me any trouble. But that was Linux, and it might be different with a windows system. Is running a halfway efficient MS SQL Server 2008 difficult? Does it require any in-depth administration knowledge? Or perhaps recurring administration effort (such as keeping the server up to date with the latest patches)? Or is it rather an "install and forget" experience similar to MySQL?

• bad pool header 0x00000019 in windows 7 home premium when connecting to net followed by BSOD.

  - by shankar

  Hi, I am have random blue screen errors with an error code of bad pool header 0x00000019 whenever I try going online. I use a usb datacard/modem but when I try logging in using a regular dsl/broadband connection, I have the same issue. I had searched the query in windows knowledge base which said it is an issue with windows 7 and have provided a hot fix which they do not gaurentee. My vendor says something is wrong with my ram and has ordered for a new set of ram, but in my opinion if it was a ram related issue, the crashes should have occured even while playing games which are supposed to be ram intensive...If you need the mini dumps I can provide you the same..Kindly revert back..

• Virtual audio driver for Windows?

  - by Ognjen

  Is there any (possibly free or open-source) virtual WDM audio driver for Windows, with additional processing plugins, which would add one more layer between windows applications and actual sound card's WDM audio driver, allowing to: Add software DSPs to general audio output. I would like to be able to use custom effects, like compressor, or stereophonic-to-binaural converter for listening online's streaming media on headphones, etc. Connect its output to some custom buffer instead of the sound card. For example, to be able to record audio, or to send audio via wireless connection to some other wireless source? Virtual audio driver was just my idea how to solve these issues - if you know other way, please share your knowledge. I need this for Windows 7 and/or Windows XP.

• What's wrong with my custom patch cables?

  - by stu42j

  I have a box of bulk Cat5e riser cable left over from when I had my house wired. I figured I could use this to make some custom length cables for connecting my computers, switches, etc. I had a crimper already so I bought a bag of RJ45 plugs. I made a few cables several years ago, but my experience/knowledge with this sort of thing is minimal. None of my cables are working. I don't have a tester so I just plug the cable into a computer and switch but I get no link light. I wired them them all straight-through and visual inspection doesn't show any problems. Any ideas what I might be doing wrong?

• How does DNS "get stuck"?

  - by Muhammad Mussnoon

  I recently registered a domain and got hosting from Dreamhost. But when even after three days, the website was not accessible, I contacted support about it. This is the response the support person gave me: "My apologies! The DNS had gotten stuck, so I went ahead and pushed that through for you. Please allow 2-3 hours for the DNS to propagate." Now I have to say that my knowledge regarding these things is virtually zero, and I couldn't understand what the support person meant, so I ran a search and it seemed that Mr. Google knew just as much as I did regarding this. Can someone tell me what "dns getting stuck" means?

• "net time" returns system error 5, "Access is denied", even when run as administrator

  - by Andrew Grant

  I am trying to run net time on a Windows 7 box with an account that is part of the Administrators group. When I run the command net time from an elevated command prompt I get the following error: System error 5 has occurred. Access is denied. Why is this happening? I've looked at this Microsoft Knowledge Base article and have gone through the steps. Both the computer and the DC are connected to the same NTP server and I've verified they're synced I'm working on a local account so there should be no permissions issues There is no local firewall running

• CentOS 5.5 APIC issue on ESX 4.1 & ML115

  - by Adnan

  Hi, I've just installed vSphere 4.1 on an HP ProLiant ML115 G5 Quad-core and am trying to install CentOS 5.5 as a guest system. However, when the guest boots up I get a calibrate_APIC_clock warning and a kernel panic message. I've come across this knowledge base article on the vmware website which suggests moving the guest onto another Intel based host (!). Funnily enough I don't have a collection of spare host servers sitting around, so can anyone suggest another solution? Alternatively, would installing an earlier version of CentOS get around this issue, or would a yum update put me back to square one? How about BIOS settings, could anything be tweaked there? Thanks.

• DNSCurve vs DNSSEC

  - by Bill Gray

  Can someone informed, please give a lengthy reply about the differences and advantages/disadvantages of both approaches? I am not a DNS expert, not a programmer. I have a decent basic understanding of DNS, and enough knowledge to understand how things like the kaminsky bug work. From what I understand, DNSCurve has stronger encryption, is far simpler to setup, and an altogether better solution. DNSSEC is needlessly complicated and uses breakable encryption, however it provides end to end security, something DNSCurve does not. However, many of the articles I have read have seemed to indicate that end to end security is of little use or makes no difference. So which is true? Which is the better solution, or what are the disadvantages/advantages of each? edit: I would appreciate if someone could explain what is gained by encrypting the message contents, when the goal is authentication rather than confidentiality. The proof that keys are 1024bit RSA keys is here.

• What's wrong with Lotus Notes / Lotus Domino?

  - by user20242

  I have a client who is using Lotus Domino for their web application/server platform. The client has two "web developers" who are more comfortable with Lotus Domino than more mainstream tools and technologies and are not enthusiastic about making a switch. I have been asked to provide an assessment of why it may be prudent to migrate to a different web application platform. I would be particularly interested in understanding deficiencies related to the platform as I have very little knowledge of Domino but am very familiar with other platforms. In addition to the fact that Apache has over 70% of web server market, IIS over 21%, and Lotus almost 0%, what other reasons would you give for moving away from this platform?

• Ouya Controller on Windows 8 to Emulate a Microsoft 360 Controller

  - by TheCompander

  I thought I'd create a central repository for those looking to get their OUYA controller working in Windows. Currently there is an underlying Windows driver issue causing the left/right triggers to be recognized as Z-Axis and Z-Rotation as well as button presses. The Xbox 360 Controller Emulator is able to connect to the controller but the underlying driver issue causes the emulated Right Trigger to remain HIGH and consequently unusable by games that look for a 360 controller (eg. Batman Arkham Origins [tested today], all buttons work except the Right Trigger). Has anyone made progress in overcoming this issue? if not would anyone know where to start to modify the controller driver to ignore the z-axis? I was intrigued into investigate this out of interest and because there is no purely bluetooth game controller on the market to my knowledge.

• Cyrus IMAP: Unable to connect to remote host: Connection refused

• Justifying a memory upgrade

  - by AngryHacker

  My employer has over a thousand servers (running SQL Server 2005 x64 and a couple of other apps) all across the country. And in my opinion they are all massively underpowered for what they need to do. Specifically, I feel that the servers simply do not have enough RAM for the amount of volume the machines are asked to do. All the servers currently have 6GB of RAM. The users are pretty much always complaining about performance (mostly because, immo, the server dips into the paging file quite often). I finally convinced the powers that be to at least try out a memory upgrade on one box and see the results. However, they want before and after metrics, so that they can see that the expense will be justified. My question is what metrics should I collect to see whether the performance truly improves on the box? I am a dev, so I am not sure how and what to collect (i have a passing knowledge of Perfmon).

• Disable ability to add startup items in Windows 7?

  - by Gam Erix

  Note: This is not the question "How to disable startup items" because the simple answer is: "Use msconfig". Now as for my question: I recently am very annoyed that some programs add startup items to my PC without my knowledge after installation, I always have 2 programs which startup - Temperature monitor and the Catalyst Control Center Tray. Now, sometimes I install something and it adds startup entries, how can I make sure that no startup entries can be added to windows anymore? So what I would like to do: -Disable adding scheduled tasks (even for administrator accounts, so programs installing from them can't add startup entries too) -Disable adding startup entries to the registry (even for administrators, would changing the permissions in HKLM on the Microsoft\Windows\CurrentVersion\Run to read only be enough?) -Disable all other methods of startup in Windows 7 I don't know -Set default startup of NEW installed services to "Start Manually" instead of/and block "Start Automaticly" and "Start Automaticly (Delayed)" How can I accomplish this? This is also a nice way to prevent most viruses fom running after machine reboot (if this can be accomplished).

• Command /Developer/usr/bin/dsymutil failed with exit code 10

  - by Evan Robinson

  I am getting the above error message randomly (so far as I can tell) on iPhone projects. Occasionally it will go away upon either: Clean Restart XCode Reboot Reinstall XCode But sometimes it won't. When it won't the only solution I have found is to take all the source material, import it into a new project, and then redo all the connections in IB. Then I'm good until it strikes again. Anybody have any suggestions? [update 20091030] I have tried building both debug and release versions, both full and lite versions. I've also tried switching the debug symbols from DWARF with external dSYM file to DWARF and to stabs. Clean builds in all formats make no differences. Permission repairs change nothing. Setting up a new user has no effect. Same error on the builds. Thanks for the suggestions! [Update 20091031] Here's an easier and (apparently) reliable workaround. It hinges upon the discovery that the problem is linked to a target not a project In the same project file, create a new target Option-Drag (copy) all the files from the BAD target 'Copy Bundle Resources' folder to the NEW target 'Copy Bundle Resources' folder Repeat (2) with 'Compile Sources' and 'Link Binary With Libraries' Duplicate the Info.plist file for the BAD target and name it correctly for the NEW target. Build the NEW target! [Update 20100222] Apparently an IDE bug, now apparently fixed, although Apple does not allow direct access to the original bug of a duplicate. I can no longer reproduce this behaviour, so hopefully it is dead, dead, dead.

• Copying Chinese Characters from PDF

  - by Kevin

  I am on a Windows 7 laptop, which I believe comes pre installed with all the language packs to my knowledge. I can see Chinese characters with no issues and normally can copy them fine. (From browser to Microsoft Office works great). I have many PDFs with chinese characters in them, whenever I try to copy them and paste them into another program such as a browser, Microsoft Office, ect I just get strange foreign characters such as: This is copying a line. It is in this order: Chinese characters, pinyin (chinese in roman letters), and then the Englis translation. ,ô t¯ing w?o shu¯o listen to me The pinyin is also getting messed up, as the tonal marks (accents) about each letter are moving to a space of their own. Any ideas on to how to fix this? Thank you very much!

• Rackspace copy script failure message "java.net.SocketTimeoutException: Read timed out"

  - by user53864

  I am using Rackspace for Ubuntu cloud server. Everyday a script(I guess the script is from rackspace) executes on the cloud servers which copies the backfile to the Rackspace CloudFiles and sends the mail as if the files are copied and I've scheduled the script on the cloud servers. I've no much knowledge of the script and I guess the script is based on Cruise(as I could see build.xml, some jar files ...). Everyday the files are copied to the Rackspace from cloud servers but sometimes don't know why, the files will be copied to Rackspace sending an error failure message or sometimes the files will not be copied and sends the error failure message like the one below. Error while backing up on Station1 on 03/03/2011 04:50 AM and reason for error is java.net.SocketTimeoutException: Read timed out Anybody using Rackspace?, anybody has any fix for this?

• Implementing a Linux-HA based clustering setup on Windows

  - by Alex

  I have a (tried and tested) setup involving: 2x Load balancing nodes on a floating IP via Heartbeat, load balancing 2 tomcat servers. 2x Tomcat servers 2x Galera Cluster MySQL servers synchronously replicating (+1 arbitrator node) All are evenly spread across 2 physical nodes. Now, I have to somehow get the same functionality on Windows Server (2008? I think) nodes .... running under Xen virtualization. There is no possibility to use Linux for any of the nodes. I count two main problems: No Linux-HA hearbeat daemon for the load balancing No Galera synchronous replication for MySQL I freely admit to having nearly no Windows knowledge when it comes to clustering. Is there a way to closely mimic the setup I have described or is it a total write-off?

• Identify Web Server from HTML File System

  - by bumble_bee_tuna

  Hi I've been given the following html file system with no knowledge of where it came from. To me this appears to be from a web server. I've been hitting Google on "Sam" smsLtd can't find to much, is this "SAM" a propitiatory web server ? Can I throw this up on an Apache or IIS server ? Reason I ask is there are some xml data files that seem to assign permissions and logins. Figured I'd ask as I have never seen it before.

• Making an apache module work only for a particular sub domain

  - by Abhinav Upadhyay

  Hi everyone. I am not a regular webmaster , I am a student working on an internship project which is an Apache2 module, so my knowledge of Apache configuration is limited. I want to configure my module for a particular sub domain of the host server. Lets say I want my module to work only for onclick.localhost , then what are the directives required ? I want the module to be invoked only for the hosts/virtualhosts for which it has been configured explicitly. I know how to setup sub domains in Apache, so that's not a problem. Thanks.

• TP-LINK TD-W8151N Modem/router as just wi-fi router

  - by Reshma

  I am planning to buy TP-LINK ADSL wifi router (model TD-W8151N) for my Internet connection which provides Internet through ADSL telephone line. I am also planning to take cable internet in a few months which provides internet through a LAN cable without the need of any modem. So I would like to have my modem work for both connections which I am using. When using cable internet I want this TP-Link modem to work just as a wireless router (so that I can have the freedom to use my laptop in different rooms instead of sitting at a place by plugging in that cable). Is it possible to use this modem in that way? I don't have much knowledge about these things except that I can configure things as instructed. Please suggest me whether I should go ahead and buy this one or if there is any other modem in your view which can serve both my purposes, let me know. Operating System I am using: Windows 7
