For my Windows Storage Server 2003, the keyboard works before Windows loads, but at the logon screen, neither the keyboard or the mouse works. I can press f8 and go to safe mode, but the keyboard and mouse still won't work.
Three days ago, I installed Symantec Endpoint Protection on the server, but there were no signs of any problems. Yesterday, I installed Windows updates, changed my network administrator's password, then I restarted the server. I also turned-on Windows firewall (I did not install Symantec with a firewall). Since then, I haven't been able to get past the logon screen. I cannot even ping the server on my network. The server is a 64bit machine, and there are no PS2 ports on it.
