We have upgraded the server from windows 2000 to Windows 2003 SP2. Upgrade was fine but now the server is not listening on port 3389 and hence RDP to this server is not working.

Hi, If you go to start -> right click My Computer, select properties -> Remote tab, is the box labeled "Allow users to connect remotely to this computer" checked? If you go to start -> control panel -> Windows firewall, on the Exceptions tab, does Remote Desktop appear and is it checked? -- Mike Burr

Hi, As you mentioned “RDP to this server is not working”, so I would like to ask whether you can remote desktop to other computers from this problematic computer. By the way, please navigate to Event Viewer to see whether there are any errors. Best Regards, Vincent Hu
