• ADUC Exchange tabs - Windows 7 & Exchange 2003

  - by John Gardeniers

  I have the admin tools install on a Win 7 64 bit machine but would like to see the Exchange tabs in ADUC. Googling shows this is a popular request and the most common solution (and the only one which appears to work to all) is to install Exchange Server Management for Vista using esmvista.msi /q. That may well have worked on beta versions of Win 7 but is definitely not working with my OEM copy of Win 7. Can this perhaps be made to work by installing from an Exchange 2007 CD (which I don't have at this time), bearing in mind that we have Exchange 2003 only? Can someone please offer a solution that works? I figure some of you must have solved this by now. Edit: I don't know if this is relevant or not but the Win 7 machine is also running Office 2010 Pro. About the bounty I had intended to award the bounty to gWaldo for having taken the extra steps to try to help me with this issue. However, as I was about to do so my screen started scrolling and I actually clicked on the answer posted by natxo asenjo, who's answer offended me, without realising it. Perhaps if I wasn't rushing I might have noticed but that's now history.

• Overscan in Catalyst Control Center

  - by alex

  I've connected my PC to my TV via HDMI (I've also tried using DVI). Whatever the resolution (anything from 800 x 600 to 1080p), the image displayed on the TV does not fill the entire screen surface; there's a black border on the edge of the image. This happens in both Vista and Windows 7. After a bit of searching I came to the conclusion it's got something to do with overscan done by the graphics card (ATI 3200HD). It's definitely not the TV because on my old PC there were no such problems. I've searched for the option in Catalyst Control Center 9.9 but it's not available for the TV; if I connect a normal LCD display, the option is there, but only for the LCD screen. If I choose Configure for my TV, where the overscan option should be, it takes me to the Welcome tab in CCC. How can I make the image fill the entire screen? How can I enable/disable overscan for my TV?

• Dell XPS 1530 DVD-RW firmware problem

  - by josecortesp

  Hello everyone. I have this XPS laptop since a year and a half ago. About 2 months ago, with the waranty expired, i tried to run the optiarc slot load DVD-RW firmware update, and said everything was okay. Then I restarted it and the problem started: Now, every single time I turn on my computer, it get stuck at the BIOS POST until the drive sounds like "ready" and then the computer starts normally. And this happen EXACTLY the same when it's getting back from sleep. I'm pretty sure is not a software issue, because I tried with Vista Home Premiun 32 bits, Ubuntu (from 8.10+)32 & 64, and with W7 64. Already tried to run the firmware installer like a million time, in case it is a failing install with no luck. Also, google it to see if someone has the same problem, and again, no. The Drive performs pretty okay once the System is on, but waiting to the drive to be ready everytime is really annoying. The Firmware I updated was this, and the drive is: K937C Assembly, Dvd+/-rw, 8, SLOT, 1530 Sony Nec Optiarc Inc. I'll apreciate any help you can give me

• GUI interfaces to ATI card behave weirdly out of the box and after updates.

  - by jdk

  My Lenovo W500 came with an ATI Mobility FireGL V5700 and both the Catalyst control center software and Vista display manager display four monitors. What's really annoying is the behaviour. My two active displays (laptop display + my external monitor) are always #s 3 and 4 respectively which doesn't make sense. This is out of the box. Additionally dragging & dropping is jumpy and displays #1 and 2 (always inactive because they don't exist to the software) are often preventing me from dragging #3 and 4 to the rightmost side. They also auto-snap to weird positions and certain sensible positions like position one directly over top of the other are not possible. The exact same annoyances are present when using the Windows Display manager too. In other words the interface is crap and I'm looking for a fix that's not wishing I had gone with nVidia instead. I've updated drivers, and Catalyst control centre. Have latest Windows and AMD/ATI updates. Any thoughts?

• Trouble with Russian pc's on my wifi

  - by hogni89

  I have created a WiFi hotspot for the local community. The problem is, some Russian PC's (Windows XP, Windows Vista and Windows 7) can't get internet connection (We have a lot of bypassing russian fishing vessels / cargo ships). The pc's obtain a valid IP address, and some of them can even manage to send some few packages - But none of them are usable on the network. They all say "Limited internet access" or "???????????? ?????? ? ????????". The thing these PC's have in common is, that they all run a Russian installation of Windows. No one else has problems with the WiFi hotspot - Danish and English Windows, Linux and OS X all work like a charm. Can it be, that there is a difference between the danish / english windows installation, compared to the Russian installation? EDIT START They can't ping the router (One PC got one response - ONCE), they can't access any sites and Windows newer asks "Is this network public, home or work?". EDIT END PS: The hotspot is a airMAX rocket M from Ubiquiti Networks, Inc (www.ubnt.com)

• Imac g5 with no OS nor CD drive

  - by sinekonata

  What I want: Ubuntu on a g5 Imac. What I have: An empty PC (Intel g5 17" Imac) with broken CD drive. Its model is A1173. This PC with Ubuntu 12.04 and an old Vista partition. a usb flash drive. Problems: No CD means the only boot Drive I could use is USB. There are no BIOS on Macs so I can't set boot settings or even see if it detects my USB drive. When I start the machine and press ALT the first and only thing I see is an old corrupted winXP partition and not a single option or additional information. So assuming blindly that the Mac hardware/firmware works normally, I don't have any Mac OS to use any of the tools that I found on different tutorials for building a bootable .img drive for macs. I can't find much software on Linux/Windows to substitute to those tools, for example among others converting an .iso file (win/linux) to .img (mac I guess). Which makes me think that the scenario where someone like me has Mac hardware but no Mac OS is extremely rare. So other than finding someone that has a Mac I have no solution. So I ask what would you do? the only thing is it should not involve any money (I know mac soft is rarely free) which also excludes getting any MacOS unless I can use a free macos.img for VM or restore the original Mac for free. Thank you

• Winamp has slow /skipping video playback on Windows 7

  - by Roy Rico

  Hello, I have Windows 7 x64 (7600 90-day trial version) and Winamp 5.6 installed. When I play a video in Windows Media Player, the video plays smooth, however when I play a video in winamp, the video is mostly ok when played back at the original size (but not completely), but if I play it back in fullscreen, the playback gets really slow. The video's audio track plays just fine. I have a DELL XPS 420 computer (8GB of RAM) with a Nvidia GeForce 8800 CTS 512 video card. I've updated to the latest drivers. I have the default Windows 7 codecs, and the CCCP codec pack which used to be all I needed under Windows XP to play all types of videos. Are the codecs needed for Windows Y the same? What's going on? UPDATE: As suggested, I turned off Aero and winamp ran just fine again. So I just have to wait for winamp to be rewritten to work with the way Vista/Windows 7 runs? UPDATE 2: Winamp has updated their player, and it works great with Windows 7 now.

• High memory utilization with firebird + windows server 2008 r2

  - by chesterman

  i have a Windows Server 2008 R2 (64bit) running a 64bit installation of Firebird 2.1.4.18393_0 in a 4GB phisical server. After a while, the task manager show that all memory is used, but the sum of the memory of all process does not stack to the half of the memory. Unfortunally, it's start swapping. Using RAMMAP, i can see that my entire database file is mapped into the memory. This only occours in windows server 2008 r2 and windows 7 64 bit. i can use firebird 32 or 64bit installations, doesn't matter. How can i prevent this? Why this only occours in w2k8r2 and w7? tks in advance ** UPDATE Aparently, this occours by the use of all memory by the file system cache. The microsoft documentations explain that this WAS a issue in windows xp, 2k3, vista and 2k8, but it was solved in 7 and 2k8r2. also adds that this issue is more common in 64bit hosts. (http://support.microsoft.com/kb/976618) there are some tools (DynCache, setcache and the Get/SetSystemFileCacheSize system calls from windows API) that allows me to fix a upper limit to the memory usage by the fscache, but the documentation argues that i should not do this in w2k8r2 because it will severely impact on the overall system performance. anyway, i tried, the performance remained the same shit and the use of the page file remained, although there is now more the 1gb of free memory.

• TortoiseSVN client slows Explorer to a crawl in Windows XP running in Parallels

  - by Cory Larson

  I thought I'd make my first SuperUser question relatively simple, though it's the kind of question that may not get many responses as I'm not directly involved with the issue. A colleague does his development in Windows XP running in Parallels on his Mac. We've just migrated our VSS repository to SVN, and we've gone with TortoiseSVN as our client of choice with the Ankhsvn plugin for Visual Studio. On his XP instance, after installing TortoiseSVN, browsing through folders using Explorer is extremely slow; about 15 - 30 seconds before the contents of the next folder displays. It's the slowest when opening My Computer. Once he reaches a folder that contains the working content of an SVN project, Explorer behaves quickly again as expected. It seems that TortoiseSVN may be spending a bunch of time searching subfolders for stuff so it can do its icon-overlay thing, but that's just a guess. I've used TortoiseSVN for years on both XP and Vista on far less powerful machines without any issues with Explorer, so I'm attributing the slowness to it being run in a VM, though that may not be the actual issue. So has anyone encountered similar performance issues, and/or know of a fix? Keep in mind that any requests to make changes to his configuration will need to be communicated and thus my response time might be slow. Thanks everyone!

• Storing Windows Updates for reuse

  - by Saiyine

  At work we update lots of computers using Windows Update. Windows XP and 7 all day long, rarely some Vista. We do it through a corporate proxy, as connecting them to a domain to build a Wsus server is out of the question, so we download about two gigabytes a day of the very same updates everyday. I've tried WSUS Offline. It's pretty complete but when it finishes it's common to be still missing hundreds of megabytes of updates, because its intention is not to fully update a system but to install the critical updates, as the developers explain in the forums. Now I'm trying with Autoupdater. It's far worse, with poor capabilities for non-English Windows XP, but at least it gives the option to install non critical updates in Windows 7. It still misses hundres of megabytes of updates after fully updating the system. And finally, both doesn't install the driver related updates of Windows 7, so they at most save us a couple of hundreds of megabytes and a reboot (with the associated login to the computer and to the proxy) out of three or four. So, is it possible to somewhat extract the installed updates in a Windows 7 system and not having to download the same updates again and again at least with machines with the same hardware? Or even better, a generic package with all the updates?

• HP dv6910 laptop no longer recognizes wireless adapter, dvd drive, and one usb port. What can I do about this?

  - by Joan H.

  In the last 3 weeks, my not even 3 year old HP laptop (vista) just seems to be failing. First, one of the usb ports stopped working. Next, the dvd drive all of a sudden was not recognized as even existing, so it is now useless. And as of today, I no longer seem to have a wireless adapter on my laptop. It doesn't show up in device manager, same as the dvd drive. I can connect to the internet by ethernet cable, but not wirelessly. It worked fine last night; now it doesn't even exist! I have tried a 'hard reset' I read about on HP's forum- no help. I am not sure what else to try. I read about the USB wifi dongle in another response, but I already have maxed our my usb ports even though I have bought a USB hub since the one port failed. Plus, I'd like my laptop to just work like it's supposed to instead of being jerry rigged with usb hubs, external dvd drives, and wifi dongles etc. Any ideas?

• How to access XAMPP virtual hosts from iPad on local network?

  - by martin's

  Using XAMPP on one machine. Multiple virtual hosts defined. One per project. Format is .local For example: apple.local microsoft.local client-site.local our-own-internal-site.local All works perfectly from that one machine. I now want to have other systems within the network access the various sites. The main reason for wanting to do this is to be able to test site functionality and layout from mobile devices without having to upload partial work to public servers. I can access the main XAMPP default site by simply entering the IP address of the XAMPP machine in, say, Safari on an iPad. However, there is no way to reach .local that I can see. Would this entail setting up a DNS server within the network? We have a mixture of Windows and Mac machines. No Linux. The XAMPP machine is Vista 64. I don't want real external internet access to be affected in any way, just ".local" pointed to the XAMPP machine if that makes sense.

• Permanent fix for unicode characters not displaying correctly (as boxes)

  - by Chase

  Please read this entire message before replying. First I know how to fix the issue on a temporary basis. I am looking for a permanent fix. I work with foreign language files a lot. Unfortunately sometimes all the unicode characters in windows explorer, notepad, and other places (as rendered by windows, probably GDI) do not display correctly. That is they display as square blocks, where as they had just been displaying correctly. There are countless methods to temporarily correct the issue. But again, I want a way to permanently resolve the issue. What I have tried: The silly "Hide fonts based on language settings". This setting only applies to what fonts you see in the fonts folder and font dropdowns. It doesn't disable foreign fonts (doesn't work, or if it does, it is temporary). Deleting the font cache file and rebooting (works.. usually, temporary solution). Changing my locale and then back (sometimes works, temporary solution). Rebooting my PC and getting lucky (50-50 chance, temporary solution). Changing my keyboard input/adding foreign keyboard (temporary solution that only seems to work once). Reinstalling windows (temporary solution, sometimes lasts a few months though, I have done this 7 times across 3 computers) What I have not tried: Buying Windows Ultimate and installing the interface packs. This is not a solution. I can't read Japanese/Chinese and I do not want my interface in those languages. What I will not do: Switch to a different brand operating system (unix, linux, mac os x) Switch to an older version of windows (Windows Vista, XP, 2000, etc). So can anyone recommend a permanent fix for the problem?

• Scenario - NTFS Symbolic Link or Junction?

  - by Unsigned

  Differences Absolute Relative File Directory UNC Symbolic link ? ? ? ? ? Junction ? x x ? x Scenario Let's assume we're creating a reparse point to create the redirect C:\SomeDir => D:\SomeDir Since this scenario only requires local, absolute paths, either a junction or symlink would work. In this situation, is there any advantage to using one or the other? Assume Windows 7 for the OS, disregarding backward-compatibility (prior to Vista, symlinks are not supported). Update I have found another difference. Symbolic Link - Link's permissions only affect delete/rename operations on the link itself, read/write access (to the target) is governed by the target's permissions Junction - Junction's permissions affect enumeration, revoking permissions on the junction will deny file listing through that junction, even if the target folder has more permissive ACLs The permissions make it interesting, as symlinks can allow legacy applications to access configuration files in UAC-restricted areas (such as %ProgramFiles%) without changing existing access permissions, by storing the files in a non-restricted location and creating symlinks in the restricted directory.

• Work from home on an iPad?

  - by Alex Basson

  The situation: My wife has a 13" MacBook Pro that she uses for email, Facebook, web surfing, and working from home. I'm about to buy us our first iPad. My wife's brother's computer just went belly-up, and she's contemplating giving him her MacBook and just using the iPad. The question is whether or not this is possible or realistic. Obviously, the iPad is well-suited for the email/web/Facebook tasks, but the working-from-home thing is an absolute must -- if the iPad can't handle that, it's a deal-breaker. For my wife, working from home means two things: Accessing her workplace computer's Windows Vista desktop, which she currently does via Remote Desktop. Editing Office documents locally, which she currently syncs via Dropbox. Being able to edit documents locally is important, because sometimes she will download documents and edit them when she doesn't have network access (e.g. on the subway). I'm more than happy to get a keyboard dock for her, so typing won't be an issue. Are there any iPad apps she can use to access her work computer and edit her work files? Thanks for any suggestions!

• Windows VPN always disconnects after < 3 minutes, only from my network

  - by hemp

  First, this problem has existed for almost two years. Until serverfault was born, I pretty much gave up on solving it - but now, hope is reborn! I've set up a Windows 2003 server as a domain controller and VPN server at a remote office. I am able to connect to and work over the VPN from every windows client I've tried, including XP, Vista, and Windows 7 without issue, from at least five different networks (corporate and home, domain and non.) It works fine from all of them. However, whenever I connect from clients on my home network, the connection drops (silently) after 3 minutes or less. After a short while, it will eventually tell me the connection has dropped and attempt to redial/reconnect (if I've configured the client that way.) If I reconnect, the connection will re-establish and appear to work correctly, but again will silently drop, this time after a seemingly shorter time period. These are not intermittent drops. It happens every single time, in exactly the same way. The only variable is how long the connection survives. It doesn't matter what type of traffic I send. I can sit idle, send continuous pings, RDP, transfer files, all of that at once - it makes no difference. The result is always the same. Connected for a few minutes, then silent death. Since I doubt anyone has experienced this exact situation, what steps can I take to troubleshoot my evanescing VPN?

• Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

  - by Maxim Zaslavsky

  I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

• DVD-burner disappears when using grub

  - by drblah

  This is a rather annoying problem I have with Linux on my laptop. Whenever I install any Linux distro that relies on grub (which is about 99 % apparently) it will mess up my DVD-drive and the drive will not be recognized after booting, no matter the OS (Ubunntu, Arch, Windows Vista or 7). I know the problem has nothing to do the DVD-drive itself, because I bought a new one a few months ago. I am also sure that grub is messing the drive up, because I have tried to use LILO, which worked fine (except for horrible boot times.) This problem have persisted through about 3-4 years and it is a pretty bad show stopper whenever I want to work with Linux. I had hoped it would get fixed over time, but no one seems to have the exact problem I have. The drive is connected with an IDE connection. Update: The old drive was a Toshiba Samsung SN-S082. I don't know the model number of the new one, but it is HP (I think). Things I have tried to fix it: Mess about with some BIOS settings like enabling AHCI and change some IDE settings. Installing a different boot loader DOES fix the problem but I would like to use grub.

• Drowning in documents - recommend doc management solutions?

  - by Martin Day

  I've been researching document management lately. I want to organise my docs at home and also at the office. Finding affordable solutions one can actually test drive is quite hard. Some that I've downloaded just don't seem to work (testing on brand new Vista PC). I've seen some software on Amazon like Paperport but not really sure what they're like. For home I'd like something to organise files, full text search, good scanner integration, nice interface etc. But for the office it seems harder. I need something that does proper workflow and keeps versions. It will have an audit trail. Documents can be approved, checked in/out etc. I know a few clients who would like something similar. It would be great just to import thousands of documents from a shared drive and get them indexed with dupes killed. I'd like to be super clear about how/where the documents are being stored so that maintenance and backups are clear. My Google/twitter searches lead back to the same tired and vague webpages pushing what look like expensive and custom made solutions. Some might be very good I suppose but it's darn hard to tell. I don't mind a hosted package but all in all I don't think something like Google Docs, as good as it is now, will work. There are too many quirks and missing features (as compared to Office). Being able to work directly with the common Office file formats is important. I've noted a similar sounding question asked here back in August but it didn't seem to turn up too many solutions that I could easily and quickly apply. Also there could have been some changes since then so I feel it's worth asking.

• Why does a document in Word 2007 stop recognizing the mouse after the document loses focus?

  - by alt234

  When I open a document in Word 2007, everything works fine, I can edit, highlight text, etc. However, the instant Word loses focus, when I focus back the document doesn't recognize anything the mouse does. The tabbed menu at the top seems to recognize the mouse but the document itself does not. I can scroll through via the scroll-wheel and I can type. However, typing just shows up where the mouse cursor last was before focus was taken away. I've tried clearing some word data registry keys. I've also found that some Word Add-ins can cause problems. LaserFiche is one I see mentioned a lot. As far as I can tell I have no add-ons though. Any ideas? It's crazy-annoying. UPDATE- - Word is the only program that has this problem - Typically I have Toad (Oracle DB management app), an XP virtual machine with various apps running on it, Skype, Google Talk, and maybe a handful of other programs at any given time open... Windows Media player, Outlook. - Yes, this happens even if nothing else is running. From a fresh restart as well. - I'm running Vista 64 with SP1 - According to Windows Update, I have the latest of everything. This has been happening for a couple of months now. Just never took the time to look into because I usually never have to use word.

• program to track recent saved files or downloads?

  - by DiegoDD

  Back to windows XP times, i used a program named Ava Find that can find any file in the system, but a really nice feature it had, called "scout bot" that automatically finds new files, that is, recently created. More info here: AvaFind For example, if i saved or downloaded a file (in any program), but i cant remember its name or where i put it, i just simply looked at the scoutbot list, and it showed me the most recent files, and then i could just open them from there, or jump to their path. Since i changed to windows 7 (passing through vista), the program no longer works. It simply keeps indexing forever and never finds anything. I don't know if it is not compatible with win 7 itself, or because the fact that my windows 7 is 64 bit. I already tried to contact the Avafind creators, but they never answered, and the program seems to be no longer supported (although the site still works). Now, is there a similar program that finds RECENT files? e.g. listing the most recently saved files, system-wide (or even limiting it to some folders, discs)? And that of course, that is confirmed to work with win 7 64 bit. I know that there are many programs that can find any file, like everything, but what i want is to find recent files and their paths, without knowing their name or e. "everything" also can sort results by date, which is almost what i need, simply to look for part of the file name or extension, and get the most recent one. but if i get to many results, it takes a while, plus, i STILL need to know the name or at least extension of the file. What i want is simply a "Most recently Saved files" tool. i.e., a replacement for Scout Bot in Ava Find. Do you know any alternative?

• Why does my computer sometimes not identify my wireless network, or others, that it always connects to?

  - by Emile Erasmus

  I have a vista operating system. Sometimes my computer will not connect to the wireless network (internet) when I start up my laptop. This happens at different places on occasion, and it is very random. It tries to connect, but can not identify the network (it does recognize the wifi name). So at the end it connects, but with limited connectivity. It can not be the hardware because all other computers connect to it fine at the same time. And it happens at different places, mostly home, but sometimes at coffee shops, etc. And then in a day or two when I start up my laptop it is all of a sudden working again. (restart does not solve the problem). I have tried all the trouble shooting options windows offers, restarting the notebook, switch modem on and off, switch laptop wifi on and of, deleted the wifi memory from the laptop and reconnected with the password as if it was the first time, everything. If it does not work at one place it does not mean it won't work at another. Example it won't work at home, then I go to coffee shop and it works, then get back home and it don't. Anyone encountered this before?

• Can't mount hard drive. Ubuntu 12.04

  - by Sam

  I am trying to recover some pictures on my 320 GB Hard Disk, so I put in a Live Ubuntu CD and am in that right now. In the devices list, it shows my USB drive, but not my 320 GB Hard Disk. I can see the disk in Disk Utility (it says it's on /dev/sda), but it's not mounted, and it says it has a few bad sectors but it is OK. In Disk Usage Analyzer, it says my maximum capacity is 13.4 GB, so it's definitely not using the 320 GB Hard Disk. I tried the following: sudo mkdir /media/newhd (worked) sudo mount /dev/sda /media/newhd (didn't work. it says I must specify the filesystem type) I then tried: fsck.ext4 -f /dev/sda (didn't work. Said: Superblock invalid, trying to backup blocks. then: Bad magic number in super-block while trying to open /dev/sda. The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock) Does anyone have any ideas? The whole problem started when my Windows Vista said "Can't find operating system". Any ideas on how I can get on to my hard drive at /dev/sda?

• computer fails to boot during/after POST for five or six boots, then works

  - by N13

  For the last few days, my computer has had issues booting. I've seen two different behaviors: The screen displays the graphics card information, then begins to list the RAM, hard drives, etc. At different points in this process (after the graphics info), the computer shuts off. After five or six attempts, it then boots normally. In roughly the same time frame, the computer freezes, and fails to boot. I think it boots successfully on the next attempt. I've also noticed that in some instances, the computer freezes on shutdown. It gets right to the point where it should shut off, but doesn't. I recently combined the best parts of two different machines into this one. I'm booting to GRUB, with Ubuntu 12.04, Linux Mint 11 and Windows Vista (unfortunately) as my OS options. It has an Enermax Modu82+ 525W power supply, and I've used an online calculator to determine that my load shouldn't exceed 400W. I even unplugged a hard drive, but that didn't help. I found the latest BIOS, patched it and checked the settings, but that didn't fix it. I'm fairly certain this issue didn't exist at first, but might have started when the power at my new apartment dropped for a second. The machine is plugged into a surge protector strip, but it's old and I've heard they lose effectiveness with age. Is a power dip as damaging as a spike? If something were damaged, why would it boot successfully after five or six attempts? It's almost like the BIOS or PSU need to be primed. The trouble with debugging is that there seems to be a "grace period" after shutdown where the issue doesn't present itself again. What should I try next?

• Is there a clean way to obtain exclusive access to a physical partition under Windows?

  - by zneak

  Hey guys, I'm trying, under Windows 7, to run a virtual machine with VMWare Player from an OS installed on a physical partition. However, when I boot the virtual machine, VMWare Player says that it couldn't access the physical drive for writing. This seems to be a generally acknowledged problem in the VMWare community, as Windows Vista introduced a compelling new security feature that makes it impossible to write to a raw drive without obtaining exclusive access to it first. I have googled the issue and found a few workarounds. However, the clean ones seem to only work on whole physical disks, and not on partitions. So I would be left with the dirty solution. In short, it meddles with the MBR to erase any trace of the partitions to use, makes Windows forget about them, then restores the MBR so we can launch the VM. I'm not sure I want to do that. Is there a way to let VMWare acquire exclusive access to the partition without requiring me to nuke it away? What I'd be looking for, I suppose, is a way to put just partitions offline instead of whole physical drives.
