• Sql Server 2005 cluster - unable to rename to old server name

  - by Paul2020

  We have a sql 2005 cluster on W2K8 cluster. It is a named instance say SRV1\A. Then I built a new W2K8 (with a diff cluster service name) but the same service account. Then I installed a new sql 2005 cluster say SRV2\A. Now when I bring down the sql server resources on SRV1 and try to rename SRV2\A to SRV1\A through the cluster admin, I get the error the network name already exists. I have tried bringing an old cluster and installing a new cluster with the same name and it works. Why am I not able to rename the name? Any advice would very helpful.

• Computer hobby and more?

  - by John

  I have been a fulltime student recently working on graduate work to complete a graduate degree. While continuing my studies I have maintained my computer hobby. However, recently my computer hobby has been threatening to turn into a full-fledged side business. Because I am starting to have people come to me for computer help who I have never met before (who generally heard word-of-mouth from other people whose computers I looked at) I am seriously considering putting my conditions for working on a computer into writing (for potential damage control and perhaps liability reasons). Are there any standards for this that I should reference? Should responsibility be waived for times when the computer is left in my care or any time I look at a machine? Any advice you can provide here would be appreciated. What other lessons have you learned that I should be aware of in relation to helping people while continuing my studies as a hobby? Thank you in advance.

• MediaTemple tcpsndbuf QoS Alerts

  - by theturninggate

  I'm hosting with MediaTemple on a (dv) Dedicated-Virtual 3.5 server. My site consists of a Wordpress blog, some custom PHP pages (nothing too intense), and I server 500-700 unique visitors per day. Despite my pretty modest numbers, I suffer from regular Apache crashes on account of QoS Alerts, mostly flagged as "tcpsndbuf". MediaTemple support -- usually tops -- has been pretty useless on this matter. I'm looking for answers as to how/why this is happening, advice on how to stop it. My website is a good portion of my livelihood, and downtime equates to lost income. Any and all help much appreciated. -Matt

• Black Screen when Computer Boots

  - by BlueRaja

  I'm having a serious problem with my computer; I think I've narrowed it down to the motherboard, but I'd like a second opinion before I spend the money. Before I moved into my new apartment, my desktop was working fine; now, it just won't work. It will turn on, the fans will spin up, lights come on... but nothing appears on the screen. No POST, nothing. I've tried: A different monitor (both are VGA) A different video-card (both are DVI, PCIe) Three different, known-good VGA-DVI adapters The onboard video port (VGA) Reseating the memory, and trying only one stick Different, known-good wall-outlets Unplugging the HDD and CD-drive from both the motherboard and PSU Replacing the PSU Has anyone had this happen before? Perhaps it's a known problem with this motherboard? Any advice!? Here are my specs: A13G+ V3.0 motherboard 2 2-gig 800mhz DDR2 600-watt PSU two older Geforce video cards

• How to debug xsane "no devices available" error on 64 bit Ubuntu 10.04

  - by BD at Rivenhill

  I have a Brother MFC-J615W printer/scanner and I wish to use the scanning feature across a network with a computer running 64-bit Ubuntu 10.04. I have installed the drivers from the Brother website and followed all of the instructions, and printing works fine, but xsane (installed from repositories) produces a popup with the message "no devices available" on startup. I recently had success with a similar approach when installing drivers for a Brother MFC-495CW on 32-bit Unbuntu 9.10, so I am aware of issues such as requiring root access if the driver permissions are not set correctly, but running xsane as root does not solve this problem. Are there any tools available to debug this problem further or does anyone have advice on how to proceed?

• How to fix error 1330 (invalid digital signature) when installing "The Rosetta Stone"

  - by victoriah

  I bought an older version of this software from a friend and the Rosetta Stone support hasn't been of much use. When installing, at the end of the process I get an error from the installer that says something along the lines of: Error 1330. A file that is required cannot be installed because the cabinet file [file.cab] has an invalid digital signature. This isn't the first time I've had such an error, some time ago I was unable to install a game I bought because of the same thing. I extracted the cab file itself just to see what it was and it's just an archive of icons and things like that, so it's not even like I'm missing out on much :/ Any advice/tips on how to work around this error would be appreciated e.g. if it's possible to make the installer ignore digital signatures. Running Windows 7.

• How to lookup an IP address in an Excel spreadsheet?

  - by Kevin Williams

  I am working with a decent sized spreadsheet of domains and server names. Another user of the spreadsheet needs the IP address for each of the DNS entries on the worksheet. Instead of manually adding and then having to maintain this list I was hoping there was an easy way to do an IPAddress lookup to display the IP address in a cell. I've seen some VBScripts that call gethostbyname, e.g.: Declare Function GetHostByName Lib "wsock32.dll" Alias "gethostbyname" (ByVal Host As String) As Long But I'm not a VB expert so I'm not sure if this is the right way to go. Any advice/links would be appreciated! also if this is a question better suited for Stack Overflow - let me know, I'm new here.

• Best way to replicate / mirror 100s of databases in SQL 2005

  - by mrwayne

  Hi, I currently host around 400-500 SQL 2005 databases of varying sizes (1-10 gig) each. I am aware of most of the different methods available and the general pros/cons of mirroring, log shipping, replication and clustering, but i am not aware of how well they tend to perform when its employed at the size i have specified (400-500 unique databases). Does anyone have any good advice on what is likely the best method for having the ability to fail over to another server with this sort of setup? Fail over does not need to be immediate, i'm just looking for something better than taking backups every day and moving them to storage. I'm preferably looking for something that would also makes it easy to manage the databases in bulk (as opposed to one at a time). Thanks for your input!

• Ideas for scaling out database architecture

  - by andrew

  We're looking to scale out our existing database architecture and need some advice on which way to go. We currently have 2 web servers behind a load balancer that both read & write to a single master database which replicates to a slave. Ideally, I'd like each of the webservers to point to their own master DB and have the data between the 2 synchronised but from what I've read, using any kind of master-master or ring-replication is discouraged. I'm looking for a general "what do other people do" kind of answer - database vendor isn't a concern at the moment but we'd like to stay with MySQL or convert to MSSQL. Any ideas would be gratefully received. Many thanks, Andrew

• How to setup separate MySQL and PHP VPS servers

  - by Fazal

  Someone recommended I should have my MySQL server separate from my Apache/PHP server in case of hacking and such. By visiting linode, slicehost and various articles here on serverfault I've managed to cobble together a decent set of instructions on how to do the Apache/PHP bit. I'm using Rackspace VPS and they provide an internal IP for each server. If I setup a MySQL VPS, should I assume that I would just add the internal IP for the database host? And I guess that I would only need to open up my default ssh port and mysql ports and install phpmyadmin on there? Ideally I would have webserver.mydomain.com and dbserver.mydomain.com (two 256mb VPS's) with servermin on webserver.mydomain.com and phpmyadmin on dbserver.mydomain.com. If anyone has any guides or advice on how to setup this type of solution I'd be more then grateful!

• How can I re-encode H.264 video with minimal quality loss?

  - by SofaKng

  I have a lot of MPEG-TS files (.TS container but H.264 video) and playback is fine except that when you skip forward/backward or fast forward it's very sluggish and gets pixelated, etc. I've been trying to do research and I'm guessing that they were encoding with very few reference blocks (ie. it's a capture from a DVB-S satellite stream). When I re-encode them with Handbrake (.MP4 container) they play very, very good and seeking in the video is instant, etc, etc. Is it possible to transcode/re-encode my MPEG-TS files with minimal quality loss? If so, what is my best bet? They are each about 2 Mbps (ie. 2 GB per hour) but I don't want to re-encode them if "minimal quality loss" requires 10+ GB per file. I'm hoping to keep the video are the same size. Can anybody give me any advice?

• Linux: Simulate Serial Connection from Arduino

  - by shanet

  I'm trying to simulate the serial connection from an Arduino into a Processing applet since I don't have an Arduino at the moment. Simply, I'm trying to just send bytes from Bash to a serial connection (on /dev/ttyS0) which the Processing applet will pick up like it would from an Arduino. I tried the answer to this question: How can I send data to the serial port from a Linux shell?, but it's simply not working and I don't know how to go about debugging something like this since I've never played with serial connections before. Any advice? Thanks much.

• PHP vs Batch file for mysql cronjob?

  - by mysqllearner

  Hi, My server details: OS: Windows Server 2003 IIS6 Plesk 8.xx installed (currently using Plesk to set the cronjob) I need your advice. I have 2 methods: Method 1: Using php + mysqldump, create databases backup files into gzip, and then send email with attachment (each databases has around about 25mb) Method 2: Using batch + mysqldump, create databases backup files into gzip, and then send email with attachment (same, each databases has around about 25mb) My questions: Whats the difference of using php file and batch file for cronjob? Which method is better in term of backup speed and send email, and (maybe)safety (e.g., lesser file corrupt occurance)? If i set the cronjob hourly, will it effect my web performances? I mean, lets say my website has 100++ users online now, and each user making transaction to MySQL, when I perform backup at my web peak hour, will it decrease the performances, like the loading speed, prone to errors etc?? (sorry for my bad english) P.S: If you need my php and batch file code, please ask me to post it here. I didnt post it now is because, its very simple and standard code.

• Why aren't connections released by the tomcat AJP connector

  - by Chris

  I have here a jboss with a web application. The tomcat is configured to use the ajp connector. Incoming connections are tunneled via an apache reverse proxy to the connector. Now I recognized that under heavy load the connector keeps a bunch of connections in "keep alive" mode for eternity and doesn't release them any more. With the normal HTTP connector the app did well, but now with the ajp connector we have regular app stallments. Can someone give me some advice where to start to look to resolve this issue? Why does the connector not release the connection again after idling for 300 secs? thanks, chris

• How do I change the URL handler for Apple Mail?

  - by Alex Reynolds

  When I highlight and right-click on text in an email message in Apple Mail 4.4 (1082), I can select "Search in Google". Despite having either Google Chrome or Mozilla Firefox set as my default web browser within Apple Safari 5.0.3 (6533.19.4) preferences, Apple Mail will open Safari, then open a new window in Safari with the search results. How do I change the default URL handler in Apple Mail, so that searches are opened in my default browser? Or is this a known bug? Thanks for your advice!

• Hardware Raid Card Reviews with SSDs

  - by Nalandial

  Yes I realize there are several questions about this but none of them seem to have the answer I'm looking for. I have two SSDs and am looking to buy a purely hardware raid card for them; however, I can't seem to find any reviews that have specifically tested hardware raid cards with SSDs rather than testing the SSDs themselves. I'm looking for a review because I'm assuming that for example: 100% gain with two 7200rpm drives doesn't necessarily mean 100% gain with a pair of SSDs, since there would be higher speeds, meaning more throughput, meaning more processor/memory usage for the card. If this assumption is wrong then that's fantastic; however if it's true, I am quite sad and would really appreciate any advice or reviews you can find. Thanks in advance!

• SharePoint Item Edit Form (editform.aspx) keeps closing webparts - MOSS 2007

  - by poolybit

  We have a custom list within MOSS 2007 which sporadically closes the edit forms web part, despite the fact that the web parts property 'allow close' is unticked. The only way to make the form work again is to edit the page in SharePoint Designer and untick the option of 'web part closed', this then allows the form to function but at a seemingly random interval it will close itself again. There is quite a large user base accessing the site/list at anyone time, also note this has happened once on another list on another site collection. Has anyone else experienced this issue before or can offer any advice?

• Pinnacle Studio 14 Importer crashes on Windows 7 x64

  - by Tuminoid

  Pinnacle Studio 14 Importer crashes on Windows 7 x64, thus I'm unable to import videos from my camcorder. I've Googled around and it seems to be a problem with x64 support in the program, but there is no info if it can somehow be remedied with Compatibility settings, XP mode. Further Googling got me this link, and none of the tips in site it links help. I've got no idea what ObjectDoct Plus 2 is (no a program or service installed by that name) which he claims causes the problem. Is that ObjectDoct critical to Pinnacle Studio and how to get rid of it (or any other advice how to make Studio 14 work on x64). UPDATE: 1) XP mode doesn't help as it doesn't handle Firewire, which is how my Canon HV20 must be connected to transfer HDV from tape. 2) I don't have that ObjectDock installed. 3) I don't wanna re-buy PS15 just to get this solved as PS14 should be able to do it.

• Fragile XenServer won't create new VDIs anymore

  - by thoiz_vd

  I'm getting increasingly frustrated with XenServer. Currently I'm using 5.6FP1 and it seems to be very fragile. Canceling any VDI-related action almost guarantees trouble. This time I tried to create a new VM using a snapshot for a template, with the fast disk cloning option disabled. It would take much longer than I was able and willing to keep my XenCenter open, so I canceled it. That took ages too, so I had to decide to "Quit Anyway." Since, I seem unable to create any new VDI. New attempts at cloning halt with "The attempt to clone the VDI failed," and creating new VMs based on built-in templates hang at "Provisioning." I'm in need of some advice how to solve this. What I did so far is run a xe vdi-list, which returned nothing odd to me, but I'm no expert. I assume that an incomplete VDI is blocking my Storage Repository somehow, however, how to deal with that remains unclear.

• Migrated SQL Server database suddenly in "Restoring" state

  - by Pete Montgomery

  Edit: This is still a live prob, less than an hour after trying RESTORE ... WITH RECOVERY. I backed up a SQL Server 2005 database and restored it to a new SQL 2008 instance. The restore was quick and successful. Everything was fine for an hour or so. Suddenly, the database is now stuck in "(Restoring...)" state in Management Studio and has a green arrow icon, and my application login is failing! Any advice? :-) Edit: This is a live application. If I delete and try again, the hour or so's data will be lost.

• Aspect Ratio on Nero 9 for burning DVD

  - by Tara

  I am currently attempting to burn a screen capture file to DVD. I will admit that I know very little about the process, the terminology, and am at a loss of how to find this information. I am using Nero 9 and am very displeased that the manuals available to me online explain very little. My current problem is that when I burn to DVD, my beautiful screen capture ends up being cropped. Through endless amounts of googling I am under the impression that this is due to aspect ratio. However, as windows will not tell me the resolution size for me to determine the correct aspect ratio I do not know how to proceed. Is there a way using Nero 9 for me to be able to burn my screen capture to DVD? Any advice or suggestions are appreciated.

• How to fix wrong icons of the files in Windows XP SP3

  - by Angel_Kitsa

  Hi everybody, Recently I deleted some folders from *C:\Windows* directory with file names like this: $some_name_Uninstall$, which are the files of the patches, which were installed on the OS. It seems like my office placed the icons in some of those folders and now all xls and doc files have no icon. (I mean no Office icon) I couldn't find a solution for this till now. Please advice if someone had such problem and/or knows the solution. p.s. I have 7 years experience with Windows XP, so please don't ask me to do simple things like associate with files again or something like that. I tried a lot of things. Uninstall and install is not a way out. Thanks for any information!

• Components needed for VPN

  - by Anriëtte Combrink

  Hi there We eventually got our Mac Mini Server. We now want to set up a small Remote Access VPN using this Mac Mini Server. Firstly we are not sure of the components needed additionally to the server to setup this VPN. We currently have the following: 1 Mac Mini Server 1 Firewall Router (Billion 802.11g ADSL2+ router with VPN capabilities [it says so on the box]) 4Mbps ADSL connection (which should have VPN capability enabled by the service provider, or so we heard) We are not sure what else needs to be included to enable our small VPN. Any advice would be really helpful.
