  This had already happened with another server (also W2003 DC), but the hardware was completely different; Unfortunately, I wasn't able to solve this year here.

  Any help or advice would be appreciated, thanks in advance

  Thank you for all your help

  I finally found the guilty service.

  It was pcmonitor monitor/remote control software. Once I stopped it is service vmware converter could get the capacity of the physical drives.

  It is rather curious because I made several servers P2V conversions using this software (so far the last one two weeks ago - the difference between that server and this one was that the first was not a domain controller).

  Hopefully this thread will help others in the future.

• Computer laptop Compaq could not start

  My laptop model is Compaq Presario CQ40-502AU. I used it for over 2.5 years.

  Recently, the laptop could not start from time to time. The LED flashes to keep, but the laptop does not start.

  Referring to this article:

  http://support.HP.com/us-en/document/c01732674

  I preformed hard reset and manged to get the laptop starts. However, the problem after several days reappered and perform a hard reset is not enough to start the laptop. Sometimes, I need to do the hard reset many times to start the laptop.

  I recorded a video on the State of Flash of the LED.

  https://SkyDrive.live.com/redir.aspx?CID=4aa65a2248b908f1 & RESID = 4AA65A2248B908F1% 21412 & parid = 4AA65A2...

  I don't know if it qualifies as keeps flashing indicating the problem on my adapter?

  Someone please help me on this. Thank you!

  Greetings,

  Disconnect the power adapter and remove the battery from the laptop. Once this is done, press in and hold the power button on the PC for a minute. Only reconnect the AC adapter and try to turn the unit back on. If this problem persists, turn off the device by pressing the power button for 8 seconds. Disconnect the power adapter and the battery. Try to start the PC again.

  If the PC starts, during the Compaq logo, press the ESC key to enter the boot menu. While in the boot menu press the diagnostic mode (should be F10) and run a diagnostics of complete systems. That should tell you which device is a failure. I hope it's nothing serious, maybe a defective battery.

  If your system seems to be stable during the startup and shutdown not randomly on its own, I would try to update the BIOS once started in Windows by downloading on:

• Reformatting laptop computer with Windows pre-installed 8

  Hi all!

  Recently I bought Lenovo Y500 with pre-installed Windows 8. I've never used Windows before 8 and this is my first time ever affected by it. I understand that Microsoft no longer use the activation key of conventional product with Windows 8 pre installed devices. Correct me if I'm wrong, but the activation key is now encrypted and incorporated in the BIOS itself. I also understand that there is a feature of system recovery and even a Clean-Install feature in Windows 8 and Windows 8 would automatically read the activation key in the BIOS while being reinstalled.
  I have read all those who want to reinstall Windows 8 and that the clean install would often suggested, but what happens if I want to reformat the laptop in all, completely destroy everything, delete existing partitions and reinstall Windows 8 after that? From a technical point of view, reformatting and repartitioning shouldn't affect the BIOS, and so I guess that if I had to reinstall Windows 8 after reformatting and repartitioning, installing Windows 8 should read the key of Activation of the BIOS always automatically and activate at the first internet connection. Or am I wrong?
  On a side note, when I bought my laptop, it did not come with the disk Installation of Windows 8, so if I had to reformat and reinstall, where I'd get the file of Installation of Windows 8? Am I supposed to download from the Microsoft Web page (if there is even a link to download it) and burn the image to a blank disc and use it to install?
  Best regards & thanks!
  Patrick

• HP pavilion laptop computer does not start

  When I turn on my laptop it does not start. It goes to a blue screen that indicates it should be repaired. Help please

  Hello

  Error code 24 characters long drive Self Test (DST) would indicate that hard is defective and must be replaced.  This is also consistent with the startup problem you describe.

  If your laptop is still under warranty, contact HP and arrange for the disk replaced - you can check the status of your warranty here.

  If you live in the United States, contact HP here.

  If you are in another part of the world, begin here.

  If you are out of warranty and would like a guide to replacing the hard drive yourself, let me know.

• Portege R100 laptop computer does not start after a while without food

  Hello

  Well there is some time, I bought a beautiful used R100 - a laptop Toshiba in passing - but now, she has developed an annoying problem. Whenever it disconnect the laptop from the power supply for more than 2 hours about (don't know if this is not longer) I can't begin the R100, even if the battery indicator is green. After pressing the powerbutton the power led lights in green, and nothing happens. The "solution" to this problem is to give the R100 some time in this 'turned on' - State and after 15 minutes, I am able to start the computer (turn market again).

  I think that this could be a problem with a battery on the motherboard that is at its limits and needs time to gather enough power to start the computer.

  I hope you can help me identify the problem with my beloved laptop :)

  Yours,

  Tobias

  p.s. I have more or less need to identify the problem and some tips how to solve - the pleasure with the surgery will be from me :)

  p.p.s. Unlike the problem of the M400 further down, I've won if the beginning focused on the hard disk to Flash. In my case the R100 does not give a glance if it does not start. - And as a reference to the other post: "Hmm, I don't remember of the R100 fan not have it at all" * huggs its r100 * "."
  And I tried unplugging all the bits of the laptop and removed the battery, waited 15 minutes and tried to turn it on. the only way to obtain the departure of r100 is the method described above.

  You have an additional RAM installed?

  Maybe you need to re-seat, or it has a intermittent or heat associated with problem.
