Hotfix for Windows XP KB954550-v5

I have a Windows Server 2003 SBS.

Yesterday I installed, according to recommendation by Windows Updates:

a. Hotfix for Windows XP KB954550-v5**

b. .NET Framework 3.5 SP1 and .NET Framework 3.5 Family Update

for .... KB961847.

I didn't realize it's "for Windows XP". Anyway, the first one went

through**. The second one failed.

(**I am assuming this was the patch I installed by looking at Control

Panel Add/Remove Programs. I didn't notice it while installing.

However, Windows Update website history does not list this patch. In

other words Add/Remove Programs is different from Windows Update web

site.)

After rebooting, it looked ok. And then I retried the second patch

again today. It failed again. The logs say it is not installed. But

now, the server now is totally unstable. It may suddenly freeze after

some minutes or after some hours. No error message, no BSOD. It just

freezes.

What can I do? Is the Hotfix for Windows XP the problem? Why is an

XP patch appllied to my Server!!!?

Thanks
