• Server 2008 Active Directory DNS Entries Deleted. Dcdiag unable to contact local AD controller.

  - by Jim Smith

  I've never seen anything like this. At a potential customer site, I noticed that the PC's were all unable to locate the domain controller and netlogon was failing. I fixed the DNS entries on the client PC's so the AD server was DNS server and tried to rejoin the domain. The PC was unable to locate the domain controller. On the server, I checked the DNS settings and while there is the high level AD folder, every single entry related to Active Directory appears to have been completely deleted. There are no backups from what I can tell and this has been happening for 6 months at least. Does anyone have any recommendations for repairing this? Thanks.

• Switching from Windows Virtual PC to VirtualBox without formatting

  - by djechelon

  I have a Win7 virtual machine running on Windows Virtual PC where I'm currently developing. I found that I dislike WVPC, and installed VirtualBox, hoping for better performance. However, importing the existing VHD into a new VM seems to not work, because even if I see the Windows boot screen, the OS will crash on a BSOD and requires the restore tool to run. That tool finds no problem, reboots but the BSOD is still present. I wouldn't like to format a new VM if possible. Is it possible to do such switching?

• Laptop hot after format

  - by Dany Khalife

  I recently formatted an HP G62 Laptop and installed all drivers from the HP site that should be installed for this model. But i noticed a very strange behavior, using Coretemp, the temp is always above 50 (on idle) and reaches 70 very quickly sometimes (Critical is 90) If i open youtube or skype alone, i can get temperatures as high as 83. Normally it was around 32 (on idle) and reaches 70 when i open games but not youtube.... I have a i3 processor and AMD graphics so i am wondering if somehow it's a graphics card issue (since i3 has integrated graphics as far as i know) Device manager shows only AMD graphics card tho, not sure if i3 graphics should appear here too. Any ideas what i might have forgotten to do after the format ?

• Unmount Mass Storage USB Device from the Command Line in Linux

  - by Casey

  I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output: $ dmesg | grep sd [20047.625076] sd 21:0:0:0: Attached scsi generic sg7 type 0 [20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error: $ gphoto2 --list-config *** Error *** An error occurred in the io-library ('Could not lock the device'): Camera is already in use. *** Error (-60: 'Could not lock the device') *** What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed. Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.

• Drivers for Quick Cam pro 9000 on Windows 7

  - by runaros

  I have a Logitect Quick Cam Pro 9000 that I want to install on my Windows 7 installation. The user manual specifies that I have to install the software before I install the camera. But my experience is that software from hardware vendors tend to decrease computer performance, so I was wondering if this camera will work by only plugging it in and letting Windows 7 find and install the drivers for it. I could've just tried installing it of course, but again, hardware vendors are notorius for fucking up things, and I wouldn't want to make it impossible to install the camera by doing things in the wrong order, hence the question here on SuperUser because I assume somebody is more knowledgeable than me on this subject.

• Hardware needs for video conversion server

  - by artaxerxe

  I would need to build a Linux server that will have as its main task to perform the video conversion. For video conversion, the most likely I will use FFMpeg tool. Question: Can anyone tell me if for improving this automated video conversion a video card will improve the process or not? The idea is that I will get movies at a very high quality that I will need to be converted in formats available for different devices (iPhone, iPad, etc.). That conversion will be performed through a CLI (command line interface). I will need that conversion to be done in the least time possible (ok, that's a kind of saying, not an absolutely specified short time).

• Remote Desktop not following display settings

  - by John

  I have my RDP client set up to use highest settings for connecting to another PC on my LAN, which has display settings 1280x1024x32bit. RDP is specifically set to use 32bit depth, but when I connect it drops to 16bit. The PC I connect to is (amongst other things) used to do some 3D graphics. I don't expect great performance, just to check it works... but it doesn't over RDP, the 3D app doesn't think the hardware is the same. Does RDP's integration with Windows mean it is providing some virtualised rendering system? Should I use something less 'clever' like VNC, to literally screen-grab the contents of the screen without altering the settings?

• CPU Temperature required for auto-shutdown.

  - by ULTRA_POROV

  At what temperature do most motherboards/cpus power down to prevent damage? And what determines this? Is it the bios, the motherboard, the cpu itself? I have a cpu that stays on in the bios until about 105 C and then shuts down. I am not sure if this is correct? Maybe the sensors are wrong. I think 105 is a bit high. I guess 80-90 would be more reasonable for an auto shutdown.

• How to create Raid 10 with megacli

  - by Henno

  I have OpenFiler storage server. Without installing Windows and MSM, I want to create raid10 array from disks 2 to 21. I have already successfully installed MegaCli to OpenFiler but I'm stuck in figuring out the correct command line for creating a raid 10 array. The documentations says that the syntax for creating a raid 10 is: MegaCli -CfgSpanAdd -r10 -Array0[E:S,E:S] -Array1[E:S,E:S] -aN My enclosure ID is 25, so: [root@linux-h5ut ~]# MegaCli -CfgSpanAdd -r10 -Array0[E25:S02,E25:S21] -Array1[E25:S02,E25:S21] WB Cached NoCachedBadBBU -a0 Invalid input at or near token E I have googled high and low but there doesn't seem to be any example doing raid10 with megaraid (only the syntax). Can anyone explain what is wrong?

• Internet connection slower than network connection speed

  - by Mike Pateras

  I've got a computer connected to a wireless router on a different floor. When I look at the network connection, I'm told the signal strength is low, and that I've got a connection of about 26mbps (often higher). However, my internet connection on that machine is very slow. Speedtests show it at about 1-2mbps, and it really shows when loading pages and video. I have fiber optic internet access, and the machine that's connected to the router/modem via cable gets the 20mbps on speed tests, and is extremely fast in every day use. My question is, is the advertised 26mbps+ connection speed perhaps inaccurate, and that my wireless bandwidth is the likely bottleneck here? Or is the signal strength what's key here? And what might I do about this? Power cycling the router helped a bit, a speed test went as high as 6mbps after doing that.

• Best way to duplicate databases nightly?

  - by Margaret

  Hey all We just got two new servers, that are running Windows Server 2008. The intent is to make the machines pretty much identical, copying the content of the master to the slave on a nightly basis, so that if anything fails, the second copy can stand in immediately. It doesn't need to be up-to-the-minute mirroring, though I suppose that wouldn't hurt if performance is not affected. The two machines will, amongst other things, each be running an instance of SQL Server 2008. The aim is to duplicate the databases on the master down to the slave on a nightly basis. Unless I'm misunderstanding, the slave databases in mirrored databases require the primary to be present to work correctly; I'm hoping for some solution where we have a second machine that can be up and running with minimal downtime if the first one falls over. Am I misunderstanding mirroring? Is that the best way to do things, or should I use some other mechanism? If so, what?

• Matte or non-widescreen laptop? Do they exist?

  - by Alan Harris-Reid

  Does anyone know of any matte-screen laptops being sold now (15.6 or 17") in the UK? All I can find is the Dell Vostro 3500/3700 range, but there is a premium of around £200 over the price of their Inspiron range (for the 17" model), and I find it hard justifying the extra cost just to have a matte screen. I do not like glossy screens, but it seems the laptop industry has gone the way of "glossy is better - let's get rid of matte". I have read and heard from other developers that as long as there are no strong light sources to reflect off the screen, one can soon get used to a glossy screen, but I am yet to be convinced. I would also be interested if anyone knows of any non 16:9 screen laptops. I find this ratio too wide and not high-enough for the work I do. 16:10 or lower would be better. Any opinions would be appreciated. Alan

• What's the best solution for file sharing in my case? DAS or NAS?

  - by jakub

  I want to have in my network small, cheap and energy efficient server with will be fully customizable (Gnu/Linux, OpenBSD). What is more I want to have big, redundant storage in my network and access to it via server. I have already small terminal without hard drive (no SATA/PATA, one drive on USB) which works fine. I don't want to buy big server, or to use regular computer for that. It's not cheap. I thought about a small case (ITX?), and cheap computer in this with SATA ports, but I cannot find anything interesting :( I thought about NAS in network and server independently and booting server from NAS, I'm not sure which technologies will be good for that, and I don't know what with performance. Direct connection to NAS through network from workstation is next pro for that. What do you think about DAS? It will be good for that?

• What desktop chipsets support AMD's Rapid Virtualization Indexing?

  - by netvope

  Rapid Virtualization Indexing (RVI) is a hardware virtualization feature that can potentially give significant performance improvement. Intel's equivalent is Extended Page Tables. See http://en.wikipedia.org/wiki/Rapid_Virtualization_Indexing for more details. My question is: Does RVI require motherboard or chipset support? If yes, what desktop chipsets support it? I've ordered a Phenom II CPU (which supports RVI) but I haven't bought the motherboard. I'll install XenServer or VMware ESXi (which both support RVI) on the new computer.

• Windows 8 cloned drive in 2nd computer

  - by Mark

  I did the Windows 8 Pro upgrade machine w/ 64GB SSD. Finding 64GB not enough, I ordered a 128 GB SSD (Samsung 830) while planning to use CloneZilla to clone the Windows 8 OS to it. I might try using the 64GB SSD (with the Windows 8 upgrade on it) as a boot drive in a backup machine. I understand that I need to do some registry work to make it happy about the SSD 'transplant,' but I am worried about having to register the same activation key on 2 computers. Am I at high risk of getting 'deactivated'? Note that the backup machine is only used when primary computer is off.

• XPP-32 over W7-64 on music production laptop

  - by quarlo

  I need to upgrade my laptop and need high performance for music production (recording and mixing). My audio interface manufacturer seems to be unable to successfully convert their drivers to 64-bit. I do not trust a virtual machine to handle real-time audio recording at low enough latency so ... I would like to install XP Pro 32-bit on a separate partition and dual boot since most of the machines that can handle this application now ship with Windows 7 64-bit flavors. I'd like to transit to 64-bit over time assuming M-Audio does eventually get a handle on 64-bit drivers, but really need to ensure that I can stay at 32-bit for now. Does anyone have any experience with this or something similar?

• Is there a Linux-compatible R/C simulator that works with real radios?

  - by Norman Ramsey

  My Dad flies radio-controlled (R/C) aircraft. He used to run a simulator called "RealFlight" which allowed him to connect his actual radio to his computer and fly simulated craft. He learned enough to fly actual planes, but he wants to move up from "trainer" aircraft to higher-performance craft. After some crashes, he'd like to go back to the simulator for a while. The catch: he's given up Windows and is now running Ubuntu. Question: is there an R/C flight simulator that Runs on Ubuntu? Allows you to connect your radio and use it to control the simulator, preferably through a USB port?

• ATI video cards - unable to use entire monitor (1080p)

  - by Walter White

  Hi all, I have a Dell s2409w, 24" 1080p monitor. With nVidia, I would plug-in the monitor and voila, it automatically knew it was 1080p (1920x1080). I have both a Windows laptop and Ubuntu laptop. Neither is capable of using the fullscreen even though the monitor reports the input is 1080p. I am connecting the monitors via HDMI, is there a 'special' setting I am missing to make this work? Otherwise, I like the performance of my ATI video cards, the drivers seem to be stable and reliable. Thanks, Walter

• Share a USB sound card over a network/bluetooth (Mac & PC)

  - by AlexW

  I've been wondering how I can stream audio to an external Edirol USB sound card, wirelessly, on both Mac and PC. I'm not looking for high quality transmission, just to play mp3s from my Mac laptop to a USB sound card that is attached to two very nice balanced studio reference monitors. Is there any way I can firstly power the sound card box, and secondly, provide with an audio stream along it's USB input. I've looked at the Belkin USB hub, and I have a Time Capsule with the AirPort interface inside. These things seem to do vaguely what I want but when it comes to audio, the specifications are less clear. Any suggestions very welcome.

• Overcrowded Windows XP Folders

  - by BlairHippo

  I know that, technically, an individual Windows XP directory can hold an immense number of files (over 4.29 billion, according to a quick Google search). However, is there a practical ceiling where too many files in one directory starts having an impact on reads to those files? If so, what factors would exacerbate or help the issue? I ask because my employer has several hundred XP machines in the field at client sites, and the performance on some of the older ones is getting "sludgy." The machines download and display client-defined images, and my supervisor and I suspect that our slacktastic approach to cache management could be to blame. (Some of the directories have tens of thousands of images in them.) I'm trying to gather evidence to support or contest the theory before spending time on a coding fix.

• please assist me debug a stack trace

  - by Eds

  I am having an issue on a windows 2003 terminal server, where the system process is using a constantly high amount of CPU. I believe that it is the srv.sys that is causing an issue, but not quite sure how to fully diagnose the problem. I have looked at the stack for the srv.sys!workerthread, which is what seems to be using the CPU. The stack is as follows: 0 ntoskrnl.exe!KeSetBasePriorityThread+0xf7 1 ntoskrnl.exe!MiDeleteAddressesInWorkingSet+0x103 2 srv.sys!WorkerThread+0x7c 3 ntoskrnl.exe!FsRtNotifyFilterReportChange+0x10 4 ntoskrnl.exe!RtClearBits+0x24 Can anyone offer any advice based on the above, or some other things I could look at in order to get to the bottom of this? Many Thanks, Eds
