• Windows Server 2008 R2 install reboots unexpectedly during "Completing installation" phase

  - by knda

  I am attempting to install Windows Server 2008 R2 onto a Cisco UCS C201 M2 rack mounted server but am having major difficulties and wondering if anyone has some insight or items they could recommend for me to look at to get this one resolved. Installation is being attempted via the Cisco remote console (using CIMC's Virtual dvd-rom).. following the first phase of Setup where the installation files are copied to the target hard drive, then a reboot occurs to load Setup from the HDD, mid-way in the "Completing Installation" phase the system then reboots unexpectedly. System configuration Cisco UCS C201 M2 (2RU rack mounted server) 16GB RAM, 2x 73GB 15K SAS, 4x 300GB 10k SAS Add-on cards - Intel quad-port GigE card (no fibre channel cards) Storage - LSI MegaRAID SAS 9261-8i. onboard SATA is disabled (no SATA drives connected) KVM - Belkin No physical DVD-ROM.. :( I have... Run memtest86+, no RAM faults Disabled/enabled SATA support (BIOS) Attempted install from USB DVD-ROM, no effect Attempted unattended install scripted via Cisco Configuration Manager DVD provided Removed Belkin KVM in case that was causing drama Discovered that the Cisco website is "awesome" for searching for PDFs/Drivers cough, reverted back to Google Downloaded latest LSI drivers from LSI's site and used during Server 2008 install checked Windows ISO against checksum's from MS site checked Windows ISO by using it for an install in a VM Running out of ways to troubleshoot this as I am not sure how to enable any sort of 'verbose' mode during the setup process. Next step I have planned is to remove the Intel NIC and try the installation again.. Edit: Problem was the "Cisco INTEL QUAD PT GBE" (1000/PT) .. will have to see if this card is faulty or if it's just drivers.. thanks for the help.

• Mainboard shuts itself off after half a second or so

  - by heishe

  Here's the problem: When I start the PC, the mainboard powers up, then stays that way maybe 0.2-0.5 seconds, and then shuts off again. I say mainboard, and not PC, because I removed all the parts from the system and disconnected everything but the mainboard power supply (the broad 12 pin thingy). When I have the other parts (cpu, graphics card, ram, etc.) installed and connected, the basic behaviour stays the same, but now the mainboard runs for about 6 or 7 seconds (this is a guess) before shutting off. This all started when my monitor wouldn't receive a video signal today, without giving POSTs, so I took the graphics card and the RAM out to see if it changes anything. It didn't, except that from that point on the mainboard would start to have this behavior where it just stays on for a very short time and then shuts off again. I already tested it with a backup PSU - same behavior. What could this be? I'm thinking it can't be on a physical level (transistors burned through or something like that), since then the mainboard either shouldn't start at all or it should detect hardware failures in non-essential parts of the syste and start beeping. Sorry, I forgot to mention. It's an MSI P67A-C43. I already checked the capacitors if someone popped, but I can't find anything. I also tried resetting the cmos, but that didn't change anything.

• My EliteBook is not auto picking 1080p for external monitor, poor display on forcing

  - by Griever

  I'm connecting my Samsung LED S22A300B to my HP EliteBook 6930p through VGA out. Laptop has Intel 4500MHD video card. I have latest drivers installed for both card and monitor. Only 800x600 and 1024x768 are shown. A lot of other people get this problem when they use it with docking station as discussed here. But I am not using any docking station. The monitor works great with my desktop though. As advised on the aforementioned page, one of the things I tried was to force the resolution using Intel's "custom resolution" feature. I installed PowerStrip on my desktop and copied advanced timing values(front/back porch,sync width, etc.) from there and then used the same values while defining a custom resolution in my laptop's Intel graphics utility. As a result, I got the 1080p resolution but the display is poor. Text has some weird colored shadow and sometimes on images too. What should I do?

• Upgrading memory on an IBM Power 710 Express (8231-E2B)

  - by cairnz

  We have a Power 710 Express server that was loaded with 4x4 GB memory on a single riser card. I have replaced the 4 chips with 4x8GB and put in another riser card and loaded it with 4x8GB more for a total of 64GB memory. The firmware is AL730_078. When i power it on, the service processor boots up and i can access the ASMi. From here I can look at "Memory Serial Presence Data" and see that the system in some way detects 8x8 GB. However when i look at Hardware Deconfiguration and specifically Memory Deconfiguration, it is still listed with old values, 16384MB, and claims there are 4x4 chips in the C17 riser. How do i proceed to make the server recognize properly the amount of memory installed? I get a FSPSP04 and B181B50F progress code on booting because (i think) it hasn't been told the memory has changed. It then does not proceed to booting the operating system (VIOS) when turned on. Are there any steps I have overlooked here? Can I do some commands, either on the service processor, or otherwise, to tell the system to configure with the proper amount of memory? PS: This is a stand alone server, not configured with HMC or SDMC.

• Picking a linux compatible motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• What LTO 4 drive to buy

  - by pplrppl

  Evan Anderson mentioned in another solution you could buy a LTO-4 (autoloader, 1 tape / day) - $4,566.00 (the discussion included total cost of tapes for a specific rotation.) but I don't know specifics on what he or you would recommend for the actual drive and if necessary controller. Show me a newegg URL or CDW, Dell, or HP, or whatever your favorite vendor would be for your solution if you don't mind looking it up or just give me a brand and a model number and I'll be glad to do the leg work myself. I currently have on have on hand an external LTO 3 drive that uses LVD SCSI interface (and thus have a controller card that has an external LVD SCSI connector). If that card isn't sufficient to interface to a LTO 4 drive let me know. http://www.fujifilmusa.com/shared/bin/LTO_Overview.pdf shows minimum tape speeds for LTO4 and other LTO formats. It looks like the IBM LTO4 actually has a lower minimum speed than the IBM LTO3. Either way my average server is too slow to feed LTO3/4 without shoeshining so I'm looking for a drive with a low minimum write speed. If you trust the PDF from 2008 that makes my choices IBM LTO 4 full height IBM LTO 4 half height HP LTO 4 half height but presumably there are other options out there that weren't mentioned in the fuji PDF. Again I'm looking for a specific recommendation on a drive to buy (and the controller if needed).

• New XPC: No video, no ethernet link, but drive spins

  - by Mike Pennington

  I bought a Shuttle XPC SH67H3 with integrated video. I installed: An Intel i5 2450P 16GB DDR3 RAM A SATA hard drive from my old linux server that still is bootable I have both power connectors plugged into the motherboard. I realize that the Intel i5-2450P doesn't have video capabilities; however, the drive spins like it's doing something useful. It seems like I should get an ethernet link light when I fire this up. I plan to run this headless anyway, so it would be really nice if I could figure out how to run this without a video card at all. I know the IP address and login info for the linux install on the disk. I plugged in speakers, but get no bios beeps when I power it up. Shuttle's bios manual has nothing in there that indicates I should have problems in this configuration. My questions: Is there a reason that the missing video card would block usage of the ethernet port? Are there settings on the motherboard / bios I can change to get this working?

• Improving abysmal 802.11n wireless network

  - by concept

  I am in desperate need of help to improve the abysmal performance of my 802.11n wireless network. At best I get 30Mbs (this is an internet download) from a technology that boasts 300Mbs, even worse is the LAN where to date best i have ever gotten is 1Mbs.

• Chipset fan on the frtiz - compressed air hasn't fixed anything - is there anything I can do?

  - by Anthony

  Yesterday, my computer started to make an annoying whining noise. Knowing that this is likely a fan issue, I opened the case and proceeded to determine which fan was causing the issue. I got some compressed air and tried cleaning out the dust around it (and the rest of the computer while I was at it). This hasn't seemed to fix the issue. Now, if it were just any fan, I would probably just replace the fan - they're relatively cheap after all. However, this is a special fan. Aside: For what its worth, I feel bad that the graphics card blocks part of the fan, but it is the only slot the graphics card fits, so I had no choice. After pulling out my motherboard user guide, it looks like this is a fan placed directly on top of the chipset. To be perfectly honest, I have no clue what the purpose of the chipset is - but it sounds important. After some quick research, I see that it is responsible for providing the bridge between my CPU, RAM and graphics, among other things. Just a quick search at Newegg tells me that chipset fans can be purchased at pretty reasonable prices (< 20 dollars). Is it practical to replace this fan? It is an old computer as computers go and I wouldn't be terribly upset to upgrade the motherboard and processor, so perhaps this is a sign.

• Copying large files from USB devices to the internal hard drive fails on Mac OS

  - by John M. P. Knox

  I have a second-generation 13" MacBook Air running Mac OS X 10.6.6 with a 2.13 GHz processor, 4 GB of RAM, and a 256 GB SSD hard disk. I often get failures when I attempt to copy a large file or large collection of files from an external USB drive (typically a "Firewire" generation Drobo) to the internal drive. The failure behaves almost exactly as if I had pulled the USB cable from the computer in mid-transfer. I get a warning that I have removed the hard disk improperly. After this event, the drive no longer appears mounted in the finder, and I have to unplug and reinsert the USB cable to mount the drive again. I have also seen a similar problem when using Aperture 3 to import a large number of photos and videos from a USB Compact Flash card reader. The import will fail and I will have to unplug the Card Reader and import the missing items. Oddly, reversing the direction of the copy seems pretty reliable. I've never had a problem copying a large file to a USB device, meaning that I have quite a few large files which are stranded on my Drobo. Model Identifier: MacBookAir3,2 Boot ROM Version: MBA31.0061.B01 I have seen a similar issue reported on Apple's website: http://discussions.apple.com/thread.jspa?threadID=2648590&tstart=0 The only suggested resolutions there seems to be switching to another form of connectivity (e.g. firewire, which does not exist on MacBook Air), or downgrading to Mac OS 10.6.4, or reverting the USB kernel extensions to the 10.6.4 versions: http://discussions.apple.com/message.jspa?messageID=12566073#12582956 I'm not too keen on the idea of downgrading kernel extensions. Does anyone know of a hardware revision without this issue that I can trade up to? Are there any other potential solutions out there?

• Why is my Network Connections list empty?

  - by DealerNextDoor

  I'm sure this question has been asked before, but none of the links I have found have worked. I've been trying to find fixes for the past couple of weeks. This all started a few days after I got my router. At first, I thought it was just something that would fix it self. But as usual, it never does. I am trying to update my router's wireless card to try and fix this problem, but I need to get the card's information to update it on the HP website. And since my Network Connections list is empty, I can't get any information about it. So to get around this, I tried to go to 'Manage Wireless Networks', and when I tried to get the properties from there, I get this error: Windows has encounter an error saving the wireless profile. Specific Error: The data is invalid. So, what all can I do to try and fix this? Any help will be appreciated. EDIT: Sorry, forgot to put router info. Router Model: WNR1000v2-V2 Router Maker: NETGEAR Router Firmware Version: V1.0.0.12NA The router is up-to-date on all updates.

• My Linux desktop sees my HDMI-connected monitor, but my monitor says "No signal"

  - by hrunting

  I have a Gigabyte H55M-UD2H motherboard and an Acer S271HL monitor. When I connect the monitor to the motherboard via VGA, signal works perfectly. When I connect the monitor via HDMI, the system "sees" the connection, but the monitor receives no signal (the monitor shows a blue box which reads "No Signal" and then the monitor goes into power-saving state). Some fun facts about this: if I hook a different monitor to this box via HDMI, the monitor receives the output without issue (same computer/motherboard, same cable, different monitor) if I connect a different computer to the monitor via HDMI, the monitor receives the output without issue (different computer, same cable, same monitor) no signal is received whether in the OS or in the BIOS there are no BIOS options for controlling video output other than for selection of onboard vs. PCI/PCI-E-based video card (the system has no dedicated video card installed) The box is running Linux, so I have the output of xrandr which shows the connection and the monitor modes detected via DDC: ~$ xrandr --prop Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 598mm x 336mm EDID: 00ffffffffffff000472ca028d128022 1c160103803c2278ca7b45a4554aa227 0b5054bfef80714f8140818081c08100 9500b300d1c0023a801871382d40582c 450056502100001e000000fd00384c1f 5311000a202020202020000000fc0053 323731484c0a202020202020000000ff 004c55573044303130383531300a01e5 020324f14f0102030405060790111213 1415161f230907078301000067030c00 1000382d023a801871382d40582c4500 56502100001f011d8018711c1620582c 250056502100009f011d007251d01e20 6e28550056502100001e8c0ad08a20e0 2d10103e960056502100001800000000 000000000000000000000000000000de Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on 1920x1080 60.0*+ 50.0 25.0 30.0 1680x1050 59.9 1680x945 60.0 1400x1050 74.9 59.9 1600x900 60.0 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1366x768 60.0 1360x768 60.0 1280x800 74.9 59.9 1152x864 75.0 1280x768 74.9 60.0 1280x720 50.0 60.0 1440x576 25.0 1024x768 75.1 70.1 60.0 1440x480 30.0 1024x576 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 848x480 60.0 720x480 59.9 640x480 72.8 75.0 66.7 60.0 59.9 720x400 70.1 HDMI3 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP2 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on DP3 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Full supported: Full Limited 16:2 audio: auto supported: force-dvi off auto on How do I get this monitor to recognize the output from this HDMI socket?

• None of usb-controllers are working after a crash

  - by Cray

  So I have a GA-p35-DS4 mboard with a Q6600, running windows7-x64. After a random crash with a bluescreen (not caused by anything particular as I recall), none of the usb-controllers are working. (And none of the devices connected to those usb ports). All the controllers are showed up in the device manager, but every one has a warning-icon (as they are not functioning properly). The windows identifies them correctly, it shows exactly the model of each controller, and it says that the driver is installed. Now, when I try to reinstall the driver (Update driver menu item in the device manager), it tries to find it, finds the driver, but quits saying that the driver was found but could not be installed. Additionally, it displays "This operation requires an interactive window station", whatever that means... Now get this, the same thing happens with a new pci-usb controller card! It is found (actually each time the machine starts, it is found as new hardware), but trying to install drivers leads nowhere, I am getting the same message about an interactive window station. (tried to install drivers from the acoompanying CD) I have tried deleting those devices from device manager and let windows find them again, but that leads to same results. None of the ports on this extension card work either. This should not be a hardware problem, a usb keyboard connected to the builtin usb controller works in bios, and even in another OS running the same computer (old xp installation) What to do? Will I have to reinstall? Can deleting infcache.1 help? Is there some way to let windows remove all old drivers and try to find all hardware again, this time only looking for drivers on a windows install disk or something?

• Ubuntu: how to get audio to work in both Spotify (under Wine) and Flash (in Firefox)?

  - by Jonik

  I'm running Spotify on Linux using Wine. Sound worked great (even though the sound test in winecfg failed!), until I installed alsa-oss package yesterday to get Flash sound working in Firefox. Now Spotify says: "There is a problem with your sound card. Spotify can't play music." So the question is, how to get the sound in Spotify working again, so that it also keeps working in Flash & Firefox? Tweak some ALSA settings? Spotify settings? Add/remove some packages? By the way, curiously, now that sound doesn't work in Spotify, winecfg's "Test Sound" does work! This is Ubuntu 8.04 (Hardy). Sound card / driver is probably an integrated AC'97. Please mention if any additional information about the system is needed! Update: I have Flash 10 installed (outside the packaging system, using $MOZ_PLUGIN_PATH env variable), but also had Flash 9 from flashplugin-nonfree package - and the earlier version was being used by Firefox! Based on what Mike Arthur said about Flash and alsa-oss, I removed the older Flash (flashplugin-nonfree package) and alsa-oss - and Flash sound still works, which is nice. But for some reason Spotify still doesn't play sound, even though things should now be like they were originally... Update 2: Got it working, all smoothly, finally.

• Converting DisplayPort and/or HDMI to DVI-D?

  - by Jeff Atwood

  Newer Radeon video cards come with four ports standard: DVI (x2) HDMI DisplayPort If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert? I did a little research and it looks like there isn't a simple "dongle" method. I found this DisplayPort to DVI-D Dual Link Adapter but it's $120; almost cheaper to buy a new monitor that supports HDMI or DisplayPort inputs at that point! There's also a HDMI to DVI-D adapter at Monoprice but I'm not sure it will work, either. AnandTech seems to imply that you do need the DisplayPort-to-DVI: The only catch to this specific port layout is that the card still only has enough TMDS transmitters for two ports. So you can use 2x DVI or 1x DVI + HDMI, but not 2x DVI + HDMI. For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

• Analyze a BSOD (irql_less_than_or_equal)

  - by Bruno Reis

  Hello. About 2 months ago I bought a new system and built it at home: Mother board: XFX X58i Processor: Core i7 920, using the stock cooler Memory: 3x2GB Corsair DDR3 1600 Video card: NVIDIA GTS 250 (1GB) Hard disk: 2x WD 500GB, 7200rpm I have 2 screens plugged into the video card, and the system is connected to a 550W PSU. Nothing is overclocked. After building the system, I stressed it a lot with Prime95 and rthdribl to check its stability. All my tests were perfect. So I reinstalled Win 7 x64 Professional and started using it normally. The first week (2010-03-15) I got the infamous irql_less_than_or_equal BSOD. Ten days after (2010-03-24) I got another one. Then on 2010-04-09, 2010-05-04. Since 2 days ago it became worse: I got one bluescreen per day! (2010-05-12, 2010-05-13, 2010-05-14). I installed BlueScreenView to try to obtain some information, but I'm not able to extract any useful information apart from the bug check string (irql_less_than_or_equal), and that it was caused by ntoskrnl.exe (the first three at ntoskrnl.exe+71f00, the last 4 at ntoskrnl.exe+70600 -- which I suspect could be the same thing, as Microsoft could have patched this file in the mean time, so the address of the function causing it changed). Then I stressed my memory sticks with memtest, they worked perfectly. After booting, I've stressed my GPU with FurMark and RTHDRIBL, everything was fine. Then I stressed the CPU with 4 instances of Prime95 while monitoring the temperature -- that never exceeded 85oC with the case closed --, everything fine. Finally I've stressed the whole system with HeavyLoad for a looooong time, everything worked just fine. So, I have stressed most of the components of the system, but couldn't get any useful information from it. Do you have any hint on what else can I do to find the culprit? Thanks Bruno

• Acer recovering windows vista

  - by Charlie Pigarelli

  My computer history is very long even of my computer has 4 years of life. An year ago I installed Windows 7 on this acer m1610 that had Vista before. My technic left me 2 recovery disc for "acer vista" before updating it to Windows 7. Then the computer had some trouble. The graphic card broke and we decided to use another computer. Yesterday I had the great idea to fuse the two computer to have a better one... So I moved the graphic card of the latter computer to the acer and everything gone well. Then the trouble of speed, it had before, come back. So I decided to reinstall the very first Windows: Vista back again. I booted the computer with those 2 DVD-R my technic left me and at the end of the process it asked me to insert "the backup cd number one or the system disk". I found 2 original Acer "Blank Recovery Disc" DVD-R and tried with those: rejected. Tried with empty DVD-+R: rejected. I tried with CDs: rejected. I don't have any system disc with me. Except for those 2 DVD-R my technic left me. What am I supposed to do now? I even tried with these fantomatic alt+f9/f10 that should start the recovery without any disc... But nothing happened. PS: the installation cannot complete if I do not insert the right disk. (The recovery disc uses Acer eRecovery Management as recovery software.

  I'm writing a class to integrate a POS card reader device to our software. In order for it to work I must know what IP it's using. We were given some sample code by the service provider and the way they do this is they open a website (http://www.ebizchargeemv.com/getip.php?mac={MAC address of device}) and it would return the IP address of the device. The device I'm using is a POSLynx220 Mini. It has an ethernet port that connects to the internet to communicate with the service provider. I send TCP data to it and the device then controls a PIN pad that prompts a client to swipe his card. It's probably a mini computer that communicates with the service provider and uses the PIN pad as its input device. Just being curious but how did they implement this? Are they implementing it using ARP? I'm planning on not using their website to determine the IP of the device. I've seen some code that uses ARP but using executing ARP in one of the PC didn't detect the POS device.

• Windows Home Server installation fails because it can't find the DVD drive anymore

  - by BBlake

  I've got an old Dell Dimension 8300 desktop I decided to convert into a WHS box. I popped in a pair of 1 TB SATA drives, which were recognized fine by the BIOS and the currently installed OS (XP), so I decided to go ahead and install WHS. Near the end of the installation, WHS acts like it can no longer find the DVD drives (either of them, the box has a DVDROM and a DVDRW). The specific error is gives is the "Can't configure storage" error. I've found several forums where people say they get this error if they remove the boot DVD during the installation (at the time of the first reboot). However, I never removed the DVD. After the error, if fails into WHS, so it did mostly install and I can work with WHS. However, it refuses to recognize the network card, video card and while it shows the two DVD drives, any CD/DVD I insert in either drive the system says is corrupted and unreadable, even though none of them are. I've tried several reinstalls both removing and not removing the DVD, but the result is the same regardless. Any other tricks anyone found? If I can't figure this out, maybe I'll just install SBS2008 and fake it up to be similar to WHS with some addin tools. Shouldn't be too hard to create something since WHS is based on SBS2003 anyway.

• IIS 7.5 Siteminder is not protecting ASP.net MVC requests

  - by HariM

  We are trying to use ASP.Net MVC with Siteminder for Single Sign on. This is on Windows Server 2008 R2 with IIS 7.5. Siteminder Agent version 6QMR6. Problem : Siteminder protects physical files that are exist. And it is not protecting the folder when we try to access a non existed file. It must redirect to login page even if the file doesn't exist when the user is accessing a protected folder. How to configure in IIS 7.5 that Do not verify a file exist, before authentication by siteminder. SiteMinderWebAgent is a Handler(WildCard Script Map) we created using the ISAPI6WebAgent.dll How to Protect ASP.Net MVC Request with Siteminder? (Added this as My previous question did not solve the problem). MVC Request shows up in IIS Log but not in Siteminder log. Update : Microsoft Support says currently IIS7.5, even in earlier versions doesnt support wildcard mappings on any two Isapi Handlers with * wild card. Currently in my case Siteminder has * wildcard and asp.net mvc (handler is aspnet_isapi) has * wildcard to handle the reqeusts. Ordered priority doesnt work in the wild card mappings case with Just *. Did not convinced with the answer but will wait till tomorrow for them to get back.

• how does a computer know which IP address will route information to the internet? [closed]

  - by JohnMerlino

  Possible Duplicate: How does IPv4 Subnetting Work? For example, I have a computer with a Network Inteface Card (NIC) which is an Ethernet card that is connected by Ethernet cables to a router. There is also another computer with a cable that is connected in another port of the router. This is a Belkin router operating over an Ethernet in the LAN. When I connect to serverfault.com, it maps to an IP address. My computer now has a task of connecting to that IP address. But my computer itself cannot connect to the serverfault IP address. Only the router can. So the task of my computer is to find the IP address associated with the node that will do the routing to the public internet. How does my computer know that a particular IP address in the local network belongs to the router, and is not another computer connected to the network? Is this information configured manually in the operating system itself? Somehow my computer must know that it must send ethernet frames to the router with the expectation that the router will then send the packet to a public IP. How does it know to send it to the router? Is the router's ip address stored in my computer like a key/value pair e.g. "router"="192.168.2.6", so that when I put a public ip address, my computer first knows to connect to 192.168.2.6?

• How can I fix video tearing and pausing on Windows XP Flash videos?

  - by xvs

  I have what should be a reasonably fast PC: it's a Quadcore Intel 6600 at 2.4 GHz, 4MB of RAM, an ATI 3800 series video card and an LG L246WP monitor, which I selected particularly because it was supposed to work well with video and have no trails or other artifacts. So I should be able to play video with no problems. And I can, as long as that video isn't Flash video. With Flash, what I see is tearing, especially during pans, and pausing -- every few seconds the video pauses for about 300ms while the sound stays continuous. I tried going into the video card setup and changing vertical sync, pulldown detection, windows media video acceleration, deinterlacing and triple buffering. but no combination of settings I've tried has changed or corrected the problem in any way. I've also tried enabling and disabling hardware acceleration in the Flash settings, to no avail. This problem happens whether or not the video is streaming or has fully streamed in before playing. So, what can I do? Is this just a flash issue or is there a way to get it to work?

• Surprising corruption and never-ending fsck after resizing a filesystem.

  - by Steve Kemp

  System in question has Debian Lenny installed, running a 2.65.27.38 kernel. System has 16Gb memory, and 8x1Tb drives running behind a 3Ware RAID card. The storage is managed via LVM. Short version: Running a KVM guest which had 1.7Tb storage allocated to it. The guest was reaching a full-disk. So we decided to resize the disk that it was running upon We're pretty familiar with LVM, and KVM, so we figured this would be a painless operation: Stop the KVM guest. Extend the size of the LVM partition: "lvextend -L+500Gb ..." Check the filesystem : "e2fsck -f /dev/mapper/..." Resize the filesystem: "resize2fs /dev/mapper/" Start the guest. The guest booted successfully, and running "df" showed the extra space, however a short time later the system decided to remount the filesystem read-only, without any explicit indication of error. Being paranoid we shut the guest down and ran the filesystem check again, given the new size of the filesystem we expected this to take a while, however it has now been running for 24 hours and there is no indication of how long it will take. Using strace I can see the fsck is "doing stuff", similarly running "vmstat 1" I can see that there are a lot of block input/output operations occurring. So now my question is threefold: Has anybody come across a similar situation? Generally we've done this kind of resize in the past with zero issues. What is the most likely cause? (3Ware card shows the RAID arrays of the backing stores as being A-OK, the host system hasn't rebooted and nothing in dmesg looks important/unusual) Ignoring brtfs + ext3 (not mature enough to trust) should we make our larger partitions in a different filesystem in the future to avoid either this corruption (whatever the cause) or reduce the fsck time? xfs seems like the obvious candidate?

• Reduce power consumption of gaming computer while idle

  - by White Phoenix

  This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 clocked @ 3.3 Ghz 3x DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 oc'd at 800/1600/1850 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) I've already seen this post Reduce power use on computer and this post How do I lower power consumption of my computer and while useful, I'm looking for answers specific to my build and OS. I'm pretty sure this build is a energy-intensive build by default, but I want to try to reduce the amount of energy my build uses when I leave it idle (when I go to bed or go out, etc). The first requirement for this machine is that I need to leave it on, so I cannot turn it off while it's being unused. I run it as a file server for personal reasons and I also leave it on in case people leave me messages on various IM services and chat clients (IRC, MSN, Steam, XFire, Pidgin, etc). I'm also unable to replace the parts in my computer with a cheaper "greener" part. What are some ways to minimize the amount of power the machine uses? I'm already using a high efficiency power supply (80 Plus Gold), but I imagine there's other things that can be done in the BIOS and Windows' power settings to reduce power usage while I'm not using the computer. From what I can tell, I can't use Sleep since that'll disable network access (whole reason why I leave the computer on in the first place). I already turn off my monitor when it's not in use. I enabled Intel SpeedStep within the BIOS (I know, I have a 965 and why am I enabling SpeedStep?) Should I bring the graphics card back to stock speeds and lower the clock on the processor even more? Main reason why I'm asking is I think this computer alone is the reason why my power bill is high, so I want to reduce its consumption to as low as possible without having to shut the thing down.

• Minimum specs needed to run 1080p HD movies?

  - by Wesley

  Hi all, I was wondering how low you could go with hardware that would still be able to smoothly run HD movies. My current plan is around $215 CAD w/o a hard drive: Intel Pentium 4 @ 3.2 GHz - 1GB DDR/SDRAM - 512MB X1600 Pro AGP - 350W PSU - ECS P4VXASD2+ - Bluray/DVD-RW drive. As for the hard drive, could I just get a 7200RPM IDE HDD? Also, I'm planning on installing XP Pro SP3, unless Ubuntu somehow has an advantage. I'm not wanting this to be a media center only computer... just want it to be a normal computer with just enough oomph to play HD movies. Thanks in advance. EDIT1: Forgot to mention that the Bluray/DVD-RW drive is SATA, but I was planning on getting an SATA-IDE adapter or a PCI card with SATA. EDIT2: Oh yes... if I get a PCI card with SATA, would you then recommend I use an SATA hard drive as well? That would leave all the IDE ports on the motherboard unused... is that a good idea?
