We had the conficker virus in March due to a WSUS server having stopped working largely. we cleaned up and patched. All PC's are ok, however this week I rebboted one of our citrix servers and got missing NTDLR message - I repaired it successfully on Monday and has been ok since. A sneaking suspicion came to me that other servers might be similarly not ok so I rebooted two more - one repaired ok. The other appeared to repair ok but will no not log onto the domain, only locally. It is a citrix server and is allowing people to us it as part of farm. So we are ok in a temporary kind of way
We still need to solve why this server won't let you log onto domain - it refuses credentials as if your name and/or password is wrong - got onw of my engineers to try just in case it was me.
So, an odd one, any ideas anyone?
