Saturday, May 05, 2012 4:43 AMLast night i ran latest Microsoft update for Win 2003 server, after the reboot none of the Workstations can connect or even ping the server which is also the active directory. From server i can ping each station. The firewall is turned off. Should i uninstall / install the TCP ?

Hi,
What you are trying to ping through client side? The signal-lab name, FQDN of the server or IP address? Please double check the Antivirus software and Windows firewall were temporarily on both server and client side.
