I'm not an administrator but software developer so pardon me if this question sound silly.
We have a client that having massive network problems that causes XP machines to timeout and break network connections and other problems with authentication (we have some LDAP based authentication services runnig on those XP machines). So few people ran all kinds of different network diagnostics and could not find anything wrong with hardware. The time problem started was correlated with the latest bunch of updates rolled on the primary domain controller (Windows Server 2008). Here's a list of updates:

People are desperate and want to rebuild that domain controller. I suggested to uninstall this last update (KB948465) that looks like SP2 for Windows Server. Is it that simple as going to "Installed Updates" and clicking Uninstall button on that KB948465? What could be possible bad consequences?
