Problems connecting to a Windows terminal server 2008 Remote Desktop

Error:
This computer cannot connect to the remote computer. Remote desktop disconnected.

1) Make sure the computer is connected to the Internet
2) Check you Firewall for any changes.

This is usually a Firewall issue - If your AntiVirus / Firewall Program needs updating and you cannot configure your Firewall, you will need to update your AV / Network Security program subscription in order to enable changing the settings, or install a different Antivirus / Network Security program.
