As well as a Remote Desktop connection users can also use a feature called Remote Assistance. Remote Assistance provides a way for users to get helpdesk assistance easier and at less cost. The user can request assistance by either saving a request to a file, using e-mail or Windows Messenger. Remote Assistance runs on top of Terminal Services which means it will use the same port as Terminal Services. In order to use Terminal Services you must open port 3389. Instant Messenger which can be used with Remote Assistance requires port 1863 to be open. Remote Assistance may also have some problems working with NAT (Network Address Translation) and Internet Connection Sharing. Remote Assistance uses Universal Plug and Play (UPnP) to traverse NAT devices. N.B. Windows 2000 ICS does not support UPnP.
