Windows 2003 server not responding to ctrl + alt + del, hanging, locking up clients trying to connect to shares.

Note (not sure if this is coincidental or related to the problems): I just loaded symantec endpoint protection across my firm.

Our windows 2003 server has recently begun not responding.  All clients attempting to connect to its shares become completely locked up.  The server is also completely inaccessible at this point (ctrl + alt + del does nothing, the screen is blue [not a blue screen of death], and I connect to it via VNC, RDP, or even check what's going on via connecting to it via another computer's computer management.  If anyone has any ideas, please let me know!  THanks

With Symantec Endpoint, there was a known issue where it locks up the server.  I called SYmantec tech support and they offered a patch that resolved the problem.

Well the first thing, as the server does not respond to anything, is to power it off (unfortunately). After a restart, does it come back ok?
Any errors on the event log prior to the time you shut it down? Check for clues there.
Also check if there is any service that gets stuck or fails to load once you reboot the box.

After a restart it ACTS normally but won't let me ctrl+alt+del to get into it.  It's not responding to VNC or remote desktop, but it IS allowing users to connect to its shares without locking up now.

Sounds like a firewall is on.

Can you get physical access and see what shows on the Main monitor.

Can you use pSEXEC or similar tools to take a look at processes?

try safe mode and see if you can log on that way.

While it is acting normally for a bit, disable endpoint protection, reboot, and watch the system for a couple of days.  You can turn it back on later but if you get the issue again you know what is causing it.
