WinXP crash with bad lsasrv.dll after KB924270 & KB885835

A client bought a Mac (don't ask) and wanted to run WinXP using bootcamp as
part of an SBS network. I got everything working OK, but when Windows Update
installed a couple of security updates (924270 & 885835), the system crashed
on reboot. The error stated that lsasrv.dll was not a valid Windows file
image. Clicking OK just leaves you at an empty blue screen.

The system won't boot in safe mode either.

The only way around it is to boot with the XP CD into the Recovery Console
and then expand that file (lsasrv.dl_) from the CD to replace the one on the
HD. However, Windows Update sees that there's an old lsasrv.dll file
installed and wants to install the same updates again. If you go ahead...
crash on boot. I tried a full Windows repair, but same issue.

Any ideas on how to get out of this vicious cycle?

Thanks.

Don't install the update, Henri. Seriously. Just Hide it.
I do not know if MS will support XP running on a Mac, but you can always
try since it is a Security update:

That's from the Security Bulletin:

Microsoft Security Bulletin MS08-002 – Important
Vulnerability in LSASS Could Allow Local Elevation of Privilege (943485)
http://www.microsoft.com/technet/sec.../MS08-002.mspx

There is no workaround for the Vulnerability on the above page.
