Remote Desktop / VNC problems

[t0rek]

I can't access my PC via Remote Desktop or VNC. Remote desktop doesn't give any error at all, the logon page doesn't come and when I psush the "Connect" button nothing happens. VNC in the other hand gives me a timeout error. However I can access other computers using both programs.
Regarding Remote Desktop, I enabled all the stuff in the Remote tab in the Sytem properties window and is allowed in the firewall. What coudl be wrong?

Are you using a router? If so, did you forward the appropriate port? I believe the default port is 3389

Yes, I even included my computer IP into the DMZ
