I have a X Series 346 server with windows server 2003 enterprise edition installed. I tried to install quick heal antivirus server edition. While installing the antivirus, all of a sudden, the server got hanged. I tried to reboot, but after rebooting i was successfully able to login, the server was stable for 2 mins, then it got stuck again. No response from the server. I can ping the server. Please let me know what is the problem.
