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 Center,
click Windows Firewall and clear the check box next to "Don't allow
exceptions".
