Note If you're running
Windows XP Service Pack 2 (SP2) and you enable Remote Desktop, Windows
Firewall will be automatically configured to allow Remote Desktop
connections to your computer. However, Remote Desktop will not work if you
have Windows Firewall configured to allow no exceptions. To allow
exceptions in Windows Firewall, in the control panel open the Security
Centre, click Windows Firewall and clear the check box next to Don't allow
exceptions. Typically, remote desktop is set to use port 3389, if you have
an external NAT enabled router or external firewall, you will need to
allow incoming port 3389. You will need to setup port mapping on your
router firewall if you are using NAT.
