• Windows 7 x64 support for Intel GMA 3650 (or GMA 3600)

  - by Loom

  I recently purchased an Intel D2700 MUD motherboard and I cannot find drivers for the Win7 x64 integrated graphics (Intel GMA 3650 aka PowerVR sgs545). The accompanying CD contains Win7 x32 version only. When I run it I got an error: This computer does not meet the minimum requirements for installing the software. I tried to use online utility Intel Driver Update Utility Graphics. I used Chrome, Firefox, Internet Explorer without success. First, UAC prompt appear, and then endlessly spinning progress-bar with text "Analyzing computer...". The text in UAC prompt is: Program file name: System Requirements Lab Verified publisher: Husdawg, LLC I downloaded this utility (intel_srldetect_4.5.5.0) and started it from my hard disk. I got an error: A network error occured while attempting to read from the file: C:\Users\Loom\Downloads\SystemRequirementsLab_intel_4.5.5.0.msi Standard VGA driver works for this video card but without hardware acceleration: Hardware acceleration is either disabled or not supported by your video card driver, which could slow game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on. Where I can get appropriate driver?

• Clone a Windows Installation to a 3TB Hard Drive; MBR to GPT

  - by DanBlakemore

  I have Windows 7 Professional 64-bit installed on my desktop. Unfortunately for me and my wallet my hard drive is failing. I have purchased a 3TB hard drive as a replacement for my current 2TB drive. I would like to avoid as much hassle as possible in moving to this new drive so I would like to copy my current partition to the new drive using Gparted. The problem is that I suspect that my current partition is MBR, and I need GPT on my new drive since it is 3TB. Can I simply copy the MBR partition onto the new disk and then convert it to GPT after the fact (can you even convert the type of a partition)? Or would I need to somehow copy the contents of the partition into a GPT partition on the new drive? How do I go about making this transistion? Also, are there any issues I should be wary of booting to a GPT partition? If it matters, my motherboard is 1 year old as of May, 2012. Edit: My motherboard is 1 day old. My old one does not have UEFI compatibility, so I decided to make an upgrade to Intel today given that I would need a UEFI motherboard to use my new HDD. How much can I use a dying hard drive (bad sectors according to Hitachi Drive Fitness Test)? I have assumed not at all, to be safe.

• erratic response times with Apache 2.0.52 on redhat 4.

  - by Kevin

  Under load, we've noticed response times from Apache vary greatly for the same 7k image. It can range anywhere from .01 seconds to 25 seconds or greater. Unfortunately, due to corporate policy constraints we are pretty much stuck on Apache 2.0.52. I'm at best an Apache novice so I'm in over my head with this problem. My focus recently has turned to our choice of MPM modules. We use the worker model on a dual core hyper threaded blade. It doesn't appear that swapping is an issue, and I don't see any signs of a hardware problem. I've read that worker is optimal on hardware with many CPU's where prefork it more suitable for our specific hardware profile. I can see conceptually how choosing the wrong MPM could result in this erratic behavior, but I'm not confident that it's the root cause here. Has anyone else seen this type of range in your response times for simple static content? What else should I be looking into here?

• Disaster Recovery Standby Server

  - by user64300

  Hi, I work for a small business with 25 users and 2 servers. 1 server is the DC running Windows Server 2003/Exchange 2003. We want a reliable disaster recovery strategy for this server without having to spend a lot of money. We take regular backups but I have been advised that only an identical server will allow them to be restored easily. I'm trying to come up with a solution that means we don't have to buy two servers at twice the cost everytime we upgrade. I'm toying with the idea of upgrading our DC more frequently (say every 3 years) and then using the old server as the recovery server (temporarily - until we can source a replacement server). However, I won't know whether the backups will restore on the old server until I try it! We're planning to upgrade to Server 2008R2 in the near future so I'm hoping the backup tools will give me some success in restoring to different hardware (or perhaps I can use hyper-v if not). So what I am wondering is whether it is a idea to use old hardware as a disaster recovery strategy (providing we regular test it obviously!).

• Route53 only for wildcard subdomain

  - by Philippe Gerber

  We recently moved our web application to AWS. One thing that is still managed by our old hoster is DNS. OLD HOSTER example.com. NS <Old hoster's name server> example.com. A <ElasticIP on EC2 instance> *.example.com. CNAME example.com. ... I'm now trying to setup and play around with Route53 and use it for name resolution of our EC2 instances. ROUTE53 web-01.aws.example.com. CNAME ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com. web-02.aws.example.com. CNAME ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com. ... Now my question: Is it possible to forward DNS queries for *.aws.example.com to Route53 (ns-xxxx.awsdns-59.co.uk.)? What kind of record would I have to add?

• AWS instance went down for restart, came back up and has been "Waiting for network configuration... " for 12 hours

  - by kavisiegel

  What happened was about a month ago, I created a new instance, re-configured everything, and mounted the old instances drive to the new one. I then detached the old drive from the instance, but it was still mounted, so it errored out. Now, come the outage last month, and when the instance boots back up - the drive isn't there, because in the downtime, it dismounted. It hangs because the fstab is looking for it. I get word that the server's not up today, I check the logs, re-attach the drive and restart. Now I'm getting "Waiting for network configuration..." and it doesn't seem to be doing anything. Some googling told me that I'm going to need to start from zero again, which I don't think is right. I created a new instance, which booted no problem, then I stopped it and swapped the two old drives into the new instance. Still the same error. Using the fresh AMI, it worked. I figure it's just a misconfigured Amazon file. I can attach the drive to a functioning instance on the same AMI and copy some files over, then try again - but I don't know where to even start or what files to check.

• Why does my computer not always automatically request a new DHCP lease when switching networks?

  - by KingJ

  I've noticed an interesting problem recently where my laptop will not automatically refresh my DHCP lease when changing between wireless networks. Instead, it will attempt to use the existing lease for the new network. Of course, since each network has different settings any connections will fail when using the old lease. While Windows will eventually request a new DHCP lease, it's often much faster for me to release the old lease and request a new, correct, lease. It puzzles me as to why this is not automatically done when associating to the network? One possible cause is that the laptop is put to sleep while connected to one network, then woken when in range of the other network. Nevertheless, I would expect that the lease would be renewed when the laptop associates to the other network rather than attempting to use the old lease. It should be noted that the two networks are completely different, both in terms of size, number of APs, network settings, SSIDs etc. One network is my home network and the other one is the campus-wide network at my University.

• Mixing both local and nonlocal addresses on three switches

  - by klew

  I have four computers that have nonlocal addresses like 150.X.X.X. Now I also get another few computers that should be only accessible through a gateway (it will be computing cluster) and they addresses are 10.0.0.X. I also wanted to include those four older computers to this new cluster, but I want them to be accessible from internet on nonlocal addresses (so I would like to set up them on both 150.X.X.X and 10.0.0.X addresses - I've set up it as interface eth0:0 since I have only one NIC). Those new computers have their switch and old computers also have their own switch. Both of them are connected to another (third) switch. The problem is that those old computers see each other (I can ping them), and also new computers see each other, but I can't ping old computer from new computer and vice versa. However pinging on nonlocal adresses works as expected. I looked into switch configuration and didn't find anything useful. I have no idea what I missed here. Can somebody help? All computers have Ubuntu Server 10.04

• Ubuntu's garbage collection cron job for PHP sessions takes 25 minutes to run, why?

  - by Lamah

  Ubuntu has a cron job set up which looks for and deletes old PHP sessions: # Look for and purge old sessions every 30 minutes 09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] \ && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 \ -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir \ fuser -s {} 2> /dev/null \; -delete My problem is that this process is taking a very long time to run, with lots of disk IO. Here's my CPU usage graph: The cleanup running is represented by the teal spikes. At the beginning of the period, PHP's cleanup jobs were scheduled at the default 09 and 39 minutes times. At 15:00 I removed the 39 minute time from cron, so a cleanup job twice the size runs half as often (you can see the peaks get twice as wide and half as frequent). Here are the corresponding graphs for IO time: And disk operations: At the peak where there were about 14,000 sessions active, the cleanup can be seen to run for a full 25 minutes, apparently using 100% of one core of the CPU and what seems to be 100% of the disk IO for the entire period. Why is it so resource intensive? An ls of the session directory /var/lib/php5 takes just a fraction of a second. So why does it take a full 25 minutes to trim old sessions? Is there anything I can do to speed this up? The filesystem for this device is currently ext4, running on Ubuntu Precise 12.04 64-bit. EDIT: I suspect that the load is due to the unusual process "fuser" (since I expect a simple rm to be a damn sight faster than the performance I'm seeing). I'm going to remove the use of fuser and see what happens.

• Unable to install drivers of any kind of device on windows 8.1

  - by saadj55

  Windows 8.1 is unable to install drivers. First, I wanted to install Android ADB drivers for my Chinese Android Phone. I downloaded the relevant drivers from the manufacturers site and enabled USB debugging on my phone and tried to install it but Windows failed to find any drivers in the driver folder. After searching on google, I got to know that I will have to edit the win_usb.inf file in order to install the drivers so I did the editing part also. Added these line: %SingleAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C03 %CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C03 to both NTamd and NTx86 sections but the problem persists. Phone's current hardware id is: VID_0BB4&PID_0C03 I noticed that I need hardware ID with &MI_01 appended at the end. But Windows detects the device with the above hardware ID. I have the webcam drivers so I uninstalled WebCam Drivers to check if they can be installed back but I am also not able to install drivers for it. Windows is detecting the camera without that &MI_01 part. Please help. I cannot install webcam nor my android phone.

• Change the logical name of sql server express 2005 database file?

  - by oob

  In Microsoft SQL Server Management Studio Express for Sql Server Express 2005, I needed to copy a database for testing and keep it on the same server as the old database. I did the following: Right Click on Databases Created new database Detached the database I wanted to copy "Restored" my new database from the backup file of my old database. I did this by clicking the 'Overwrite the existing database' box on the Options pane, and I changed the paths in the 'restore as' options so that they pointed to my new .mdf and .ldf files. Everything is working like I want. Problem is, when I right-click - Properties - Files on my new database, the logical name of the .mdf file is the same as the logical name of the old .mdf file. They are actually different files - they just share the same logical name? I guess maybe this isn't a short-term problem, but I can see it confusing somebody down the road. Any way to change the logical name of the .mdf file? UPDATE EDIT - Apparently you can just change the logical name through the GUI by, get this, clicking on it and typing a new name. I could swear that was not possible when I posted this, but maybe it was and I somehow missed it! Either way - the solution below should still work but doing it through the GUI is also an option.

• How to diagnose a spontaneous reboot?

  - by Spectralist

  My computer reboots, seemingly completely at random, about once every week to two weeks but has occasionally gone months. It just goes from running fine to the POST with no error messages or anything and doesn't seem to be due to heat or usage as it's happened a couple of times when the computer has booted just a few moments ago and is idling. It's been happening for as long as I've had this computer, almost two years. It's happened in both Vista and Windows7. I strongly suspect it's a hardware problem. But due to the rareish and random nature of the crashes my normal strategy of just removing hardware until the problem stops isn't really practical. My guess would be Power Supply, Ram, or Motherboard. But I just don't know how to test an issue this random and want to figure out how to confirm which it is before I go replacing things. So is there some software or hardware that can be used to test these sorts of errors? I did run memtest86 for about 8 hours without finding any issues. And the power supply is more than capable of running my system.

• Swapping RAID sets in and out of the same controller

  - by hazymat

  This is a really simple question, and the answer is probably encoded in various wikipedia articles, however my question is reasonably specific, and I need a bulletproof answer! I'm not sure if my question pertains to hardware RAID in general, or to the specific RAID controller I'm working on. Either way it is the Dell SAS 6/iR (this is an LSI sas1068e chipset). I simply want to: remove a set of striped (RAID 0) disks from this RAID controller in a server put in another set of disks, and create a RAID 1 array (or create a new 'virtual disk', as they call it in the SAS 6/iR manual) Do stuff with the new RAID 1 array Have the option of putting back the old set of disks (the RAID 0 striped ones) I am quite sure this is possible, but I need some form of reliable, evidence-based answer as it's for a client of mine, and I need to migrate their data safely. The question: can I actually do the above? Does the RAID configuration get stored on the disks themselves, or in the hardware controller? Is any data stored in the hardware controller? If there is any chance I cannot completely restore operation of the first set of disks I removed, then I need to know about it! The manual alludes to the answer to this question (see page 45 of this document), and talks about activating an array of disks. I just need someone to confirm I can definitely do the above. See, simple question, right? :)

• Connecting WD World Book to my new laptop using downloaded win 7 driver

  - by Jeanie

  HELP!!! I have just been reading through and seeing that you can connect using a USB straight to your laptop. This would be great is I actually had the cable! My problem is I have a lovely new laptop with windows 7 - I had to buy this as my old laptop isnt working anymore and I have just ordered an external sata enclosure to see whether I can get any inormation of the old drive and put onto my new laptop, so at least I don't lose any work. This in itself will probably present problems as my old OS was Windows XP! I will deal with that when i get to it!! My problem at present is that I have a World Book and I wish to connect and configure it to my new laptop but again I need to download drivers for Windows 7, which I believe I have done, but now I can't seem to work out just what to do next to help these 2 devices to recognize each other and configure. If anyone has any answers or could talk me through it I would be really grateful. Thanks - Jeanie

• Logging won't stop on log file after renaming/moving it.... how do I stop it?

  - by Jakobud

  Just discovered that logrotate is not rotating our firewall log. So it's up to 12G in size. I need to split up the file into smaller chunks and start manually rotating them so I can get things back on track. However before I start splitting the firewall up, I need to stop the firewall from logging to the current firewall log file and force it to start logging to a new empty file. This way I'm not trying to split up or rotate a log file that is still constantly growing. I tried to simply do this: mv firewall firewall.old touch firewall I expected to see the new empty firewall file to start growing in size, but no... the firewall.old is still be logged to. Then I tried to start/stop iptables. No change. firewall.old is still the log file. I tried to move it to another directory. That didn't help. I tried to stop iptables, then change the filename and create a new firewall file and then start iptables again, but no change. How do I stop the logging on this file and force it to start logging on a new file?

• Did Windows 7 Startup Repair trash My Documents?

  - by Metaphile

  Earlier today, I rebooted my computer. Partway through the boot process, it shut down suddenly. When I tried again, I was prompted to run Startup Repair, and I did. Afterwards, my computer booted normally and everything seemed to be in order. Then I noticed that my My Documents folder contains a mix of old and new files. On closer inspection, it appears that Windows has reverted my system to a previous state. Two things puzzle me: 1) According to Microsoft, "System Restore does not affect personal files, such as e-mail, documents, or photos [...]", yet many of my personal files have been affected. 2) Why were some things reverted, but not others? I had recently reorganized a bunch of files in My Documents. The reverted directory structure seems to be a hybrid of old a new, with a lot of new stuff missing. It's hard to say for sure, but it looks like the stuff that's missing would have been in conflict (two folders with the same name, for example), and Windows favored the old stuff. Is this normal behavior for Startup Repair/System Restore? To modify personal files, I mean? Is there a pattern to the mess it's made of My Documents?

• How do I remove a printer connection without the user's intervention?

  - by 1.618

  Here's the situation: We're replacing 11 printers with newer models, and we'll be installing them on our print server and sharing them out. The plan is to share the new printers under different names than the ones they're replacing, and un-share the old ones. So I need to come up with a way to remove the client connections to old printers automatically. Clients are mostly Windows 7 with a few XP. My first idea was to call prnmngr.vbs from the login script to remove each old printer explicitly by name. The problem is that some users don't log out when they're done for the day, so I can't count on their login script running before they next need to print. I could remotely run prnmngr.vbs using SCCM, but if it's not 'impersonating' the user, I don't think it will remove their printers. Any ideas? Could I lookup how to access WMI using c# code and write a "trojan" to remove specific printers without requiring the user to do anything? (I'm only half joking). I'm open to any suggestion! Thanks!

• Diagnosing PC crashes (most often while using shared folders or torrents)

  - by Dyppl

  For the last few weeks my PC (pretty old P4 with WinXP SP3) has been crashing randomly. It just suddenly reboots instanteneously. It feels hardware-related but I wasn't able to determine wether it's software or hardware that causes it. I did notice a pattern though: it's more likely to crash when I copy a lot of files over network or have uTorrent running, but sometimes it crashes when I am not doing anything with it. Copying files from it over network causes it to crash in 1 to 10 minutes almost every time. Using torrents causes it to crash every 1-3 hours. With neither or that on it crashes every 24 hours or so. I ruled out the following probable causes: PSU (I bought a new one and turned off most of the drives so the power is sufficient 100%) Bad HDD or interface cable on my SATA disk from which I was originally copying the data over network (bought new SATA cable and later yanked out the HDD completely, PC still crashes without it) Video adapter (AGP slot is now empty, using the onboard VGA at the moment) Network adapter (removed it from PCI, using onboard LAN) CPU (I think: I changed the termopaste and it's temperature is below 50C) RAM (I think: I ran Memtest86 and it didn't show any errors) At the moment I only have only one system HDD and DVD drives, a mouse and a keyboard plugged in. The fact that it crashes most often when I use network extensively makes me think that maybe it's software related (I removed the network adapter from PCI and now am using an onboard one, so network hardware is unlikely to cause problems). I am now pondering system reinstall but it's not a pleasant solution so I decided to ask wether there are better ideas first. If someone can share a good diagnostic tool it would be great because I didn't find anything good. Thanks in advance, I hope that "help to diagnose" questions aren't entirely banned here. EDIT: Motherboard is actually ~4 years old as I replaced it back in 2007

• TFS 2010, can I migrate source code only ?

  - by driis

  Our old TFS 2008 installation is getting old, and we would like to migrate to TFS 2010. However, the structure of our team projects is not so well thought out, and there has been various experiments with process templates and editing of work items and so on. Therefore, I would like to migrate our source code to TFS 2010, with full history, and keep all other aspects of the new TFS 2010 installation as clean as possible. How can I do that ?
