New sysprep.exe ( for Server 2003 SP2

Here’s the file that you need for Server 2003 SP2 (kb926028): x86 / x64

Personally I couldn’t get the download to run properly on my Vista box (didn’t actually try very hard) so I ran it from an admin console with the /x switch.
It extracts some rubbish into a folder along with the that you want.
