I have a problem with a server (Server 2008R2 x64) where RDP stopped working after windows updates were installed.
I've done due diligence and googled to find that this is a pretty common issue with update KB2621440 having been installed prior to installing the SP1 update later. Basically the proposed fix I've seen in multiple places is to reinstall that update.
Unfortunately every time I try to install that update, it fails. If i do it through windows update, i just get "an unknown error occured" (how helpful!).
I've also tried downloading the update manually from microsoft, and it also fails.
I also ran the "windows update preparation tool" from microsoft, which happily completed.
Anybody have any insight in to this?
