This Hotfix didn't work on my 2008 Server std. (SP2) working as PDC.
After installation and boot, server restarted over and over again by itself.
I had to replace the "system"- file from "system32 - config" from a backup to boot the server correctly.
Eventlog told me "This hotfix doesn't fit the system!" ==> WHAT THE F**KING HELL...???
Now DNS and some other instances dind't work anymore, so I deinstalled the hotfix, now everything's fine again.
So think twice before you install this on a server...!
