This is a very curious situation.
Last week we installed Trend Micro worry Free Business advanced version 7 on our windows SBS 2008 server. Out of the sudden the server stops downloading emails through our pop3 connectors. Also no one on the network can authenticate to the network.
Even the remote connection doesn't work at all. It hangs at "configuring remote session" and stays there forever.
As soon as we restart the server (by forcing it since we can't even log in at the console) everything seem to go back to normal. and then, at some point it closes any new connection.
I've been searching the event log for some clue without any chance (maybe I wasn't looking at the good place.
I need to mention that I've uninstalled MS Forefront that was already expired since couple of months.
Does any one has ever went through such problem with WFBS before ?
