• Windows 7 BSOD Crashes

  - by Shane Andrade

  I recently upgraded to Windows 7 64 doing a clean install from Vista 64 and ever since I keep getting random blue screen crashes. I have the feeling it's caused by my video card but everything has the most up-to-date drivers for Windows 7 64 bit. Here is the memory dump from my most recent crash: MEMORY_MANAGEMENT (1a) # Any other values for parameter 1 must be individually examined.

• Determine the time difference between two linux servers

  - by Paul

  I am troubleshooting a latency network issue on a network. It is probably a nic or cabling issue, but while I was going through the process of figuring it out, I was looking at the timings of a ping packet leaving a network card and arriving at another server. Both linux. So I have tcpdump running on both, and I issue a ping from one to the other, and back again, and looking at the timing differences might have shed light on where the latency is coming from. It is an academic exercise now, as I need to eliminate some more fundamental causes, but I was curious as to how this could be achieved. Given that ntpd is installed and running on two servers, how can I confirm the current time discrepency between the two servers, to whatever level of accuracy is possible - given that we are talking about latency on a local lan, which is ideally a millisecond or so. NTP itself is accurate to a couple of ms under good conditions, and as both servers are in the same environment, they should (presumably) achieve a similar level of accuracy, and so should have a time discrepency between them of a only few ms - but how can I check this?

• Can't get an IBM xSeries 345 server to load Windows Server 2003 using ServerGuide utility

  - by Kyle Noland

  I have a client that has an IBM xSeries 345 eServer. Per the IBM support website, I have downloaded the ServerGuide Setup 7.4.17 installation ISO and burned a bootable CD. The CD boots fine and loads the utility. I walk through the following screens without any issue: Set the date and Time Detect the IBM ServeRAID card and install the latest firmware Clear the hard disks Set up the RAID array The next step is format the NOS partition. I select my partition size and the utility goes through the following steps: Creating NOS partition Formatting NOS partition (NTFS) Copying W32 files The copying W32 files takes about 10 minutes. I see the CD drive and disks working hard. When the copying is complete, I'm taken to a blank page just NOS Partitioning at the top. At the bottom of the screen are the familiar Back and Exit buttons. I see the place where the Next button should be, and if I click on it I can tell there is something there, but the space is empty. No button is displayed and clicking the empty spot doesn't ever take me to the next screen. I can't load the OS until I get past this part. I have already tried: Burning multiple copies and versions of the ServerGuide CD Letting the final screen just sit there over the weekend thinking it might advance after syncing the drives or something Has anybody else seen this? I'm really at a loss here.

• Graphics and USB devices freezing soon after OS loads

  - by Andrew

  I run Ubuntu/Windows dual boot. Last night I started the upgrade to Ubuntu 12.04, and my computer has not worked since in either Windows or Ubuntu. Here's what I got when I rebooted after the upgrade, and continue to get every time I boot: Gets to GRUB screen OK. Choose Ubuntu - black screen or crazy purple lines. At first I assumed something went wrong with the upgrade (often happens). Choose Windows - works fine, I log in, but soon after that the graphics freeze (sometimes with purple artifacts). The keyboard and mouse (both USB) also lose power at the same instant, and none of the USB ports have power to them. This happens sooner or later every time I boot. Update: the HDD also appears to lose power at the same point. I have tried a live CD, but my computer refuses to boot any CD even after disabling all other boot options in the BIOS. I have disconnected everything except keyboard, mouse, graphics card with one monitor, one RAM sick and HDD; no change. I also took the little battery out to reset CMOS. I am pretty sure no matter how wrong the Ubuntu upgrade went, it wouldn't cause the above symptoms in Windows. So the only explanation I can think of is that a hardware failure occurred at the same time. Some possible causes of this I can think of are: A couple of days before this, I added a third screen (which worked fine). About a week before, my house lost power in a storm (no ill effects over the past few days though). What can I do, other than buy a new motherboard/CPU and hope it works? Unfortunately I don't have another box to swap parts into to test at the moment.

• restoring a failed SBS 2000 box...

  - by Brad Pears

  Hi there, I read a post where you had mentioned you have had a PERC card blow up on you in an SBS box... I've got a similar situation where one of my RAID drives failed and then the power supply failed before I could replace the drive... I then replaced the power supply and the failed drive and reconfigured the RAID array. I had a recent full backup of the my Win2k SBS's C: drive stored on my SYmantec backup exec server so I installed win2K server on the c: partition and then once I had that up and running, installed the backup exec agent so as to do a restore of the entire c drive including system state. THis all worked just fine, until I had to reboot. I received an "incorrect drive configuration" error and then it hangs. I figure that likely makes sense becasue I think my RAID array is configured slightly different now in that the partitions may be sizeded ever so slightly differently now than they were before I think... Is there a way I can just restore from my backup BUT maybe exclude some of the registry and hidden boot files it wants to restore so that it is booting with the current configuration now active on that machine - not the pre blow up configuration files? I also read a post that indicated you might have to install the exact same service pack etc... etc.. before attemting a restore but that does not make sense to me being as the entire c drive contents are going to be overwritten by the restore anyway? THe basic OS install is just to be able to get the backup exec agent installed . I can;t understand why one would need to install the exact same SP level. CAn you shed some light on what I might be able to do to get this thing up and running? Thanks,Brad

• Blender refuses to start

  - by Sekhemty

  I'm trying to run Blender under Linux, but I'm unable to do that, whenever I try I get some errors. I'm using Kubuntu 12.04 with KDE 4.11.1. This is my video card: ~$ lspci | grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV610/M74 [Mobility Radeon HD 2400 XT] I used to have installed the fglrx proprietary Catalyst drivers, but lately they gave me some system-wide problems and I had to revert to the open source Mesa drivers (I don't think that these details are important, but just in case, the whole story is here). Whit the fglrx drivers Blender was running fine, but now, whenever I try to start it, I get this error message (some parts are in italian, but I think that they are easily understandable): ~$ blender connect failed: No such file or directory Writing: /tmp/blender.crash.txt Errore di segmentazione (core dump creato) The content of /tmp/blender.crash.txt is as follows: # Blender 2.68 (sub 5), Revision: 60150 # backtrace /usr/lib/blender/blender() [0x877a41f] [0xb7756400] /usr/lib/i386-linux-gnu/libLLVM-3.0.so.1(_ZN4llvm3ARM8SPRClassC1Ev+0x15) [0xa8f4a9d5] /usr/lib/i386-linux-gnu/libLLVM-3.0.so.1(+0x25ca48) [0xa8eefa48] /lib/ld-linux.so.2(+0xeeab) [0xb7765eab] /lib/ld-linux.so.2(+0xef94) [0xb7765f94] /lib/ld-linux.so.2(+0x12fa6) [0xb7769fa6] /lib/ld-linux.so.2(+0xeccf) [0xb7765ccf] /lib/ld-linux.so.2(+0x127f4) [0xb77697f4] /lib/i386-linux-gnu/libdl.so.2(+0xbe9) [0xb4ff9be9] /lib/ld-linux.so.2(+0xeccf) [0xb7765ccf] /lib/i386-linux-gnu/libdl.so.2(+0x133a) [0xb4ffa33a] /lib/i386-linux-gnu/libdl.so.2(dlopen+0x47) [0xb4ff9c97] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(+0x3cbf0) [0xb7717bf0] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(+0x4079d) [0xb771b79d] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(+0x1a3aa) [0xb76f53aa] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(glXQueryVersion+0x2e) [0xb76f0cee] /usr/lib/blender/blender(_ZN15GHOST_WindowX11C1EP15GHOST_SystemX11P9_XDisplayRK10STR_Stringiijj18GHOST_TWindowStatei25GHOST_TDrawingContextTypebbt+0x11c) [0x8f54aec] /usr/lib/blender/blender(_ZN15GHOST_SystemX1112createWindowERK10STR_Stringiijj18GHOST_TWindowState25GHOST_TDrawingContextTypebbti+0xd7) [0x8f4f4a7] /usr/lib/blender/blender(GHOST_CreateWindow+0xb6) [0x8f4cf86] /usr/lib/blender/blender(wm_window_add_ghostwindows+0x205) [0x8799be5] /usr/lib/blender/blender(WM_check+0x50) [0x877b670] /usr/lib/blender/blender(wm_homefile_read+0x111) [0x87859f1] /usr/lib/blender/blender(WM_init+0xd2) [0x8787872] /usr/lib/blender/blender(main+0xe6e) [0x873848e] /lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0xb4e694d3] /usr/lib/blender/blender() [0x8778a99] The only thing that I can guess from this report is that the mesa drivers are somewhat involved, as I already suspected, but I don't have a clue on what I need to do to try to solve the issue.

• USB mouse disconnecting and reconnecting in windows and linux

  - by Kalak

  I have a problem similar to what is described at "Why is my USB mouse disconnecting and reconnecting randomly and often?" except is is happening in both Windows 7 and Linux (Ubuntu 12/04TLS, fully patched), multiple mice, multiple OSs. It stops responding to input for about 3-5 seconds, then starts responding again. It's more frequent and lasts longer when running games (TF2, L4D, Dishonored, Borderlands 2, and more), but happens when just running the OS as well. I was hoping it was the motherboard so I bought a USB 2.0 PCI card to try that, but it's still happening. I've stripped it down to just the keyboard and mouse (different keyboard too just in case the keyboard was the problem), but it's still happening. All the hardware (mice and keyboards) work fine on other computers. I have literally pulled the mouse and keyboard out and plugged them into another computer (laptop) and re-joined the online game and had no problem with the keyboard and mouse combo that just failed on my gaming rig. Please no driver / Windows or Linux only suggestions, as that wouldn't effect both OSs. edit: known good mice I've brought home are now going bad. I suspect the hardware is messed up (voltage?) and has been frying the mice.

• Mac Security - Which one?

  - by Bob Rivers

  Hi, Recently I had my credit card cloned. A few hours after shopping at an online store (in which I trust and buy since 2006) I received a call from my bank asking if I recognize a $5,000 debt to a store(?!) called Church of Christ... I'm a Mac user (OS X 10.6.3). I always kept my system updated and I have firewall enabled (in my Mac and in my broadband router), but I decided to adopt some kind of protection. I don't want to rise passionate discussions. Real or not, snake oil or not, I need to have back my peace of mind... I read this and this posts. I selected two software that I think that could help me (both have more features other than just an antivirus). Does someone have feedback about Intego's VirusBarrier X6 or Trendmicro's Smart Surfing? Intego solutions seems to be better, but TrendMicro brand/name is stronger in corporate environment, so their solution should be good. Both solutions have 30 day free trial, but I would like to hear something from you. Any other solution that I should look? TIA, Bob

• windows cant "see" camera

  - by user330401

  So I bought a lil emerson camera and I am trying to get it to read the thing on windows 7. The instructions for the camer say when you first hook it up via usb AUTOPLAY will come up and your good to go. Well that worked for me the first time I hooked it up. However the 2nd time, it started trying to install drivers. Since then I can't get it to show up in windows explorer. I have tried disabling and uninstalling everything and trying to start from scratch but its useless, I'm stuck with having to pull the sd card everytime. I really dont like doing this as its a cheap camera, so if I can fix the communication between the devices via usb I would be really happy. As of right now the device installation shows a checked USB COMPOSITE DEVICE and 3 X'd GENERIC IMAGE DEVIC. Can someone please help me get this sorted. PS there are no drivers for this camera, not in the packaging, not available from emerson, and to be honest it shouldn't need any. The only function the camera has when hooked up via USB is charging and access to the DCIM. The charging still works, but the drive just won't load. Any suggestions?

• Ubuntu 12.04 froze during update, won't boot

  - by Cichol

  I've recently installed Ubuntu 12.04 on my laptop, and every time i tried to update it, it would freeze for a few seconds, and tell me that the updates could not be downloaded. After many, many tries I managed to get them downloaded, but then in the middle of installing them, it froze. Completely. No mouse movement, no blinking lights, no nothing. After a few hours of letting it sit there, I finally hit the power button to do a hard reset, and now when I select Ubuntu on the boot screen (Dual-boot with Windows 7), I get a blank purple screen, and then nothing. Another freeze. I've tried getting into the console, but no command I input has any visible effect. I have a ton of music stored on the partition it's in, so I'd really rather not have to reinstall. My specs, to the best of my knowledge: Clevo Corp model B7130 (Sager custom) CPU: Intel Core i5 @ 2.53gHz (4 CPUs) Graphics Card: Nvidia GeForce 425m 4096 MB RAM Drivers: Whatever comes with the download of 12.04. As a side-note, I installed Ubuntu via the Windows Installer program (wubi). Does that make a difference?

• Something very strange with network

  - by Rodnower

  Hello, I have Windows 7 and I have very strange thing with my network. Some time I was connected through wireless router and my IP was 192.168.2.103, router's IP was 192.168.2.1 and some other IP was 192.168.2.100. The last I get from page "active DHCP clients" of web interface of the router and from "wireless clients" I may to see that 192.168.2.100 not (!) belong to my MAC address. Router build by EDimax.

• Least CPU intensive way of streaming your screen on windows?

  - by sinni800

  Hello, sometimes I like capturing my screen for others to see. Only thing: I am playing games while I do it. I have tried a few streaming solutions where Windows Media Encoder coupled with my own Windows server appealed to me most, because I can change resolutions, etc. I also tried ustream coupled with the Flash applet and the Adobe Flash Encoder recording a Camtasia source. Camtasia has the disadvantage though that it shows the green-and-black-alternating borders and can not be targeted fullscreen. I like how xfire does it. But it doesn't work with every game, many are simply not supported. A few thoughts about this: Is there a program which captures like Fraps or XFire (based on Direct3D and OpenGL outputs) and exposes the output to a DirectShow source filter? Which brings me to: Is there hardware accelerated capturing directly from the graphics card? Maybe including direct encoding with help from OpenCL? Modern graphic cards decode BluRay content directly for example. I should have a modern enough graphics processor for this to be possible (see below). If using Windows Media Encoder: Which are the least CPU intensive settings? Which codec? Is there a newer codec than Windows Media 9? Is it less CPU intensive? I only have 7, 8 and 9 inside the Encoder Could the performance be massively increased by having a Quad-Core CPU (see below)? Bandwidth is no problem up to 1000 to 1500 kbit/s (I have 2048). My Computer specs: Intel Core 2 Duo E8400 4 GB DDR2-800 Ram Ati Radeon HD5770 Using Windows 7 Professional

• Problems starting autossh on boot [ubuntu]

  - by Ken

  I'm trying to automatically start an SSH tunnel to my server on boot from a ubuntu box. I have an ubuntu box that's mounted on an 18-wheeler and is networked behind an air card. The box hosts a mysql database that i'm trying to have replicated when the aircard is connected. As I can never be sure of my IP and how many or which routers I'm behind I'm connected to my replication server with an SSH tunnel. I got that working using the following command: ssh -R 3307:localhost:3307 [email protected] Now I'd like that to start whenever the box is, and be alive all the time, so I installed auto-ssh and setup this little script: ID=xkenneth HOST=erdosmiller.com AUTOSSH_POLL=15 AUTOSSH_PORT=20000 AUTOSSH_GATETIME=30 AUTOSSH_DEBUG=yes AUTOSSH_PATH=/usr/bin/ssh export AUTOSSH_POLL AUTOSSH_DEBUG AUTOSSH_PATH AUTOSSH_GATETIME AUTOSSH_PORT autossh -2 -fN -M 20000 -R 3307:localhost:3306 ${ID}@${HOST} I've tried putting this scrip in /etc/init.d/ and using a post-up command in /etc/network/interfaces as well as putting it in /etc/network/if-up.d/. In both situations the script starts on boot, but the tunnel doesn't appear to be correctly established. The script works when run manually.

• Windows XP mounting USB drive to same letter as previously mapped network drive

  - by GAThrawn

  Why does Windows always mount a USB drive as the next drive letter after the last physical drive, even when that letter is already taken by a mapped drive, and is there any way to improve this behaviour? What happens is I tend to use a few different flash drives on my PC, as well as having both a Blackberry and a personal phone that mount as USB drives when I plug them in to charge. Being on a corporate PC I also have a number of mapped network drives (some set by login script, some set as persistent mappings in my profile). When I first login I'll have drive letters like this: C: - Local Drive D: - DVD Drive G: - Login script mapped drive J: - Login script mapped drive When I plug the Blackberry in it'll mount two drives (one for onboard storage, one for the SD card) as E: and F:. If I then plug in another USB drive it will mount as G:, even though that's already taken by a network mapped drive. This leaves me with the following drives: C: - Local Drive D: - DVD Drive E: - USB drive (Blackberry) F: - USB drive (Blackberry) G: - Login script mapped drive [G: - USB drive - mounted but not visible in Explorer or command prompt] J: - Login script mapped drive I then have to go into Disk Management, find the new USB drive that's mounted to G: and re-assign it to another letter eg Z:, once this is done Auto-Play detects it and throws up its normal dialog, and its browseable in Explorer. While this is OK to do if you only use one or two USB drives and have admin access to your PC with your login account, its a total pain in the proverbial if you regularly use a whole load of different USB devices, and corporate policy means you have one account for your normal login (that only has User access to workstations), but have to use a different account for any privileged action. I realize that one possible reason for this is the difference between hardware which is mounted and assigned drive letters at the systen level, and mapped drives which are done at the user level. For USB devices that are already plugged in before login, then obviously they're mounted before Windows knows what network drives may be mapped. However if you plug the USB devices in after you're fully logged in and have drives mapped then Windows must know which letters are available?

• I need help choosing between two configurations of the Dell Studio 14

  - by Adnan

  There are two configurations of the Dell Studio 14 (1458) which I'm looking at: Config 1: Core i7-720QM @ 1.6 GHz; ATI Mobility Radeon HD 5450 1GB; 4gb DDR3 RAM @ 1066 MHz; 500 GB SATA HDD @ 7200 RPM; Price: $999 Config 2: Core i5-430M; ATI Mobility Radeon HD 4530 512MB; 4GB DDR3 RAM @ 1066 MHz; 500 GV SATA HDD @ 7200 RPM; Price: $874 What I want to know is, would config 1 still be able to do decent gaming (maybe some Starcraft II), and is there a great performance difference between the i5 and i7 processors? Is the $130 extra worth it for the i7 and better graphics card? I do more than just basic computing. I plan on getting into web design (specifically using Photoshop and Dreamweaver), and I wish to do gaming. I know Conifg 1 is the better value, but I want to be sure that the $130 more is truly worth it. I dont have too much money and want to spend wisely as possible, yet I am a computer geek and plan on doing a lot more than the average user.

• Windows 7 64bits installation via USB asks for drivers

  - by Shikiryu

  I just bought a new config ( ASUS p8z68-v lx, i5-2500k + ram and new graphic card ). Coming back and installing it in my old computer, I just saw that my DVD player was on IDE (yup…). So, I needed to install windows 7 64bits from my usb key. Fine, I made my usb key bootable and copy the official DVD on it (the same version that was on my old computer), set BIOS to boot on it first and started the computer up. It worked fine until it asks me for cd/dvd drivers (which is funny since, I do it via USB because I can't plug in my DVD player :D) I have 3 SATA HDD plugged in and that's it. I made a small google search and found that it could be SATA or RAID drivers. Fine, I took another USB KEY and put all my motherboard drivers on it (from the CD sold with the MB) and none of those drivers seemed to work. I tried downloading new drivers from ASUS website and same effect. Any idea but no "buy a new DVD player", I'm now broke for the month :) ?

• Why do I have 55 local area connections in ipconfig?

  - by RMorrisey

  Windows Vista Home Premium. I should mention that I am having no problem whatever getting an internet connection. When I type "ipconfig" in the console, I get (55!) messages of 3 lines each, listing a ton of disconnected network connections. My PC only has one network card. Each message looks like this: Tunnel adapter Local Area Connection* 55: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : These don't cause a major problem; they make it a pain, though, to fish upward and find my IP address. How can I get rid of them? Edit: Actually, a few connection numbers are randomly missing from the sequence; so, it's really more like 30 or 40 connection messages, rather than all 55. Not sure why that is, either.

• Computer causing WiFi interference?

  - by Mannimarco

  I came back from college and brought my desktop computer. Family recently switched to Verizon FIOS and got a new router because of it. Unfortunately, my connection to the new wifi network is awful, with the download speeds (tested through speedtest.net) fluctuating wildly and often dropping below 1.5 Mbps. A laptop in the same room gets 20 Mbps. I've tried a new wireless card, thinking that mine got damaged in the move home but no luck. Here's where it gets weird: if I place the laptop near the computer, the laptop's download speeds often suffer greatly. Pulling the laptop away always fixes this. So now I'm under the impression that there's something in the computer (which I built a year ago and has had 0 issues up to this point) is causing an insane amount of wireless interference. Also bizarre: the upload speeds seem unaffected by this problem. On the laptop and desktop, upload speeds are generally around 5 Mpbs. Any ideas as to what could be causing this and how to test said theories would be fantastic.

• Hyper-V Virtual Machine Networking issues related to Max Ethernet Frame Size

  - by Goatmale

  I fixed an issue today earlier today but i'm interested in learning WHY it worked. We set up a new Hyper-V virtual machine only to discover that HTTP traffic wasn't working. HTTPS, pings, everything else was working fine. After months of prodding around I took a shot in the dark. On the Hyper-V host server, the physical NIC card had an advanced setting of "Max Ethernet Frame Size" set to 1500. After setting this setting to 1514 the issue was fixed. Alternatively, setting this to 1512 did not solve the issue; 1514 is the magic number. My best guess it that when this setting was set to 1500 it was allowing incoming pings because the data payload was a lot smaller of say, HTTP traffic. As far as HTTPS traffic, I read about something called "Path MTU discovery" which i'm going to assume why is HTTPs traffic was getting through fine, albeit slower. Looking at this post, people agree that 1518 is the max total frame size. Why didn't I need to change this to 1518 instead of 1514 bytes? Why is the default frame size 1500 if that's the max size of the Ethernet payload and not the max size.

• COMPAQ Tower No Signal to monitor

  - by Lancelot

  Hi there, I have had some troubles with this: I received a compaq tower: Compaq Presario SR1224NX Onboard VGA Windows XP SP2 from a friend. It was given to me on condition i give her the files back. My plan was to turn this into an Ubuntu Server. It booted up no problems even with the ubuntu live disc. After a normal shutdown(not unpluggin the power cord and not doing a hard shutdown with the power button), it would not restart even after SEVERAL attempts. I realized the light next to the power supply would flash very rapidly. I researched and found out it was one of two things: a dead power supply or the cables to the motherboard and to the disks etc. Thus i checked to ensure the cables were fine(and they were). I purchased a Power Supply (this one has 400 watts, the initial had 250) and installed it. The tower now boots. It booted into the live disk and everything. After a normal shutdown, it now restarts but is not sending signal to my monitor. I have tried several monitors in which i assure work perfectly but not with this tower(i recall it did show display after replacing the power supply). The monitors are ACER. This is different than most "no Signal" problems since i am not using an external Video Card, this is onboard VGA. Thanks!

• How do I know what hardware to buy to meet my needs?

  - by Darth Android

  While Stack Exchange does not permit shopping recommendations, it doesn't provide any general advice to consider when buying hardware. So, instead of just telling those that ask what to buy that it's not allowed, let's tell them how to figure out what they need. When looking forward to build a computer, how do I know what to buy? How do I find out if a given CPU will be enough for a certain game or application that I want to run? How do I find out if a given graphics card will be enough for a certain game or application? What is important when looking at motherboards? How much memory do I need? How do I know how much wattage I need for a power supply? What size case do I need? What relevant standards do I need to read up on and be aware of? PCI, PCIe, SATA, USB 2.0, USB 3.0, etc... What "gotchas" do I need to be on the lookout for? Please keep responses generation-agnostic to ensure they will be helpful to our future users. :)

• Can a hardware firewall block a server accessing its OWN UNC shares?

  - by Simon

  I need to set up a UNC share for my hosted dedicated server to access a share on itself. Unfortunately TFS requires a UNC share. I am on a Windows Server 2008 Standard SP2 64bit dedicated server behind a PIX 501 firewall hosted with GoDaddy. I just cannot get the server to access itself and get this error: Windows cannot access \\SERVER\SHARE Check the spelling of the name.. etc. I've found numerous questions about this but no answer to my problem. Server 2008 Standard x64 SP2 Workgroup - not domain Windows Firewall is off Computer browser service is on I am trying to access \\MYMACHINE\TFS-BUILDS by typing in - or double clicking. Neither works. Machine has single network card Filesharing wizard says share was ok Share was showing under 'Computer management' Permissions are set to 'everyone' full control No obvious errors in eventlog Reboot didn't fix it Unfortunately I cannot try to access other shares in or out of this machine because it is a hosted dedicated server and the only machine behind a hardware firewall. The only thing left i can think of is that the hardware firewall needs to be configured. Is this possible? Does 'UNC traffic' go out of the machine and then back in again?

• Media Center - TV constantly pauses 1/2 second then plays 1 second

  - by Bob

  I have a problem watching TV in Media Center. The TV constantly pauses 1/2 second then plays 1 second, pauses 1/2 second, plays 1 second - it is constant and does not vary. I know the problem is Media Center because I can use Pinnacle's TVCenterPro and there is no skipping/pausing. I was using cable, and switched to DirecTV (satellite). Trying to do "Set up TV signal" in Media Center seems to be what broke it. I get an error "IR Hardware not detected." I can use the remote to "try again" - so the IR hardware works fine (Media Center's remote/sensor). I tried plugging the IR Blaster into both ports, and I tried a different USB port for the IR receiver. I can't complete the setup. Media Center was playing it okay before I tried to run setup. (I ran setup to try to do recording with Media Center.) Pinnacle PCTV 800i HD PCI card, ATI Radeon HD 3200 Graphics, Windows XP SP3 Media Center Edition, AMD Athlon Dual Core 2.5 GHz, 1.75 GB RAM.

• Why a 10 years old software still is so slow even today?

  - by Cawas

  I just noted this question due to a game (which happens to be Diablo 2), but the matter of fact is: why is my brand new mac book pro, made in 2009 with latest technology (tho it's the cheapest one) can't rival my computer which used to run this much faster back in 2000? Really, it was much faster on my AMD K6 450 back in those days, and I could even run two clients at same time with no slow down. I've always had the feeling this machine was slow, but this is a very odd way to attest it. Granted, the machine is smaller, runs on wifi and "boots" way faster thanks to sleep mode. But other than that, what have we evolved after all?! I'm pretty sure this shouldn't be graphical card's fault. Sure if I buy latest technology it will run fast, and probably most people here can confirm this and won't even understand my question. But the thing is, all the hardware is supposedly much faster and better than the stuff from 10 years ago. The software and operating system became more complex, but also more well refined. Now I'm trying a piece of software that is actually 10 years old and it's not getting any better results! Why?

• Windows 8: Clean Install Fails BEFORE country Screen

  - by Mark

  G'day, I've been trying to (clean) install Windows 8 on my PC now for over two weeks now, and it's really getting old. You can see here that I've outlined my issue to the Windows Technical Community, which has resulted in... absolutely no help at all. http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_install/windows-8-clean-install-fails-before-country/64229d0a-0220-45a9-bdc6-c41062df8a75 Tl;dr? Yeah, me too. Basically, I've shrunk the HDD, it's working (I'm on that PC on XP). I've put both the x64 and the x86 DVD's, AND an another HDD with W8 installed on it from my test machine, and they ALL Fail to load. (I get the slanty windows logo, and after about 10 seconds BOOM. Sad face error screen.) I really don't want to have to remove the video card, or the unevenly/not partnered DIMM in the 2nd Memory channel - because the case is .. stupid, and in an awkward spot, but I'm running out of ideas! PS. I tried turning on ACHI tonight. All that resulted in was XP wigging out about new drivers & explorer.exe crashing. Fun times! :(
