Hi there A challenging question for you gurus out there. one of my windowXP Pro machines has a problem with its remote desktop service. I am sure it wasn't the firewall. Everytimes a machine (client) try to connect to it (server) with remote desktop, I saw from the Process Explorer that there were 2 new processes created (csrsss.exe & winlogon.exe) in the server machine but were dropped immediately. There was no error messages to both client and server sides. From the client side point of view, it feels like the server machine is not responding. any idea? thanks in advance!
