Quickfix: VMWare Server WinXP Pro Guest: STOP c000021a 0xc000026 after Windows Update

leave a comment »

Problem: After installing a bunch of Windows updates (from “scratch” WinXP SP2 CD, on a VMWare Server 1.06 w/Ubuntu Hardy host), can’t boot Windows XP, even in safe mode, with following blue screen of death:

STOP: c000021a {Fatal System Error}
The Session Manager Initialization system process terminated unexpectedly with a
status of 0xc000026c (0x00000000 0x00000000).
The system has shut down.

Workaround: I have no explanation for this (but google kb925902 bsod and let me know what you find) — reversing/uninstalling KB925902 got me past the BSOD. Use WinXP recovery console from the CD, and do:

cd C:\winnt\system32\$NtUninstallKB925902$\spuninst
batch spuninst.txt

The fact that this reverses a security is update is a little unnerving. See http://support.microsoft.com/kb/925902, GDI fixes tend to be important (a recent vulnerability used specially crafted .jpg files). Do not leave your system unpatched.

In my case, I was able to successfully install WindowsXP-KB925902-x86-ENU.exe and reboot without a blue screen.

I should note I installed Internet Explorer 7 along with 70 updates without a reboot in between (I was not asked to reboot). This could have something to do with it.

Quickfix: VMWare Server WinXP Pro Guest: install hangs at “installing devices”

leave a comment »

Problem:When installing Windows XP Pro as a guest on VMWare Server 1.06 (host Ubuntu, not that it matters), Windows XP setup hangs at “Installing devices”.

Cause: Windows XP needs a driver for the “virtual LSI Logic SCSI adapter”, which is the default in VMWare Server. Previous versions of VMWare did not use this device, so an F6 driver wasn’t needed.


Download vmscsi- (1.4 MB), and mount it as a floppy image in your VM. Hit F6 when Setup asks, hit S, select “VMWare SCSI Controller” and hit ENTER.
