After installing KB974571 the OCS server might stop working with events like this (se below)
The solution for now, is to remove KB974571 again and stop automatic install update if it’s turn on. just do the setting “download but let me choose when to install them” for now.
After removing KB974571 you need to restart the server.

Update Update :)
Update: client update, this is not the case (or at least not on my XP client)
But on my Windows 7 it’s a problem having kb974571 installed
User desktop that has the KB974571 installed will not be able to login.
Remove the KB974571 from the desktop PC and restart, this should fix the problem.
