XP Pro Remote Desktop
• The host computer must be part of a network in which Remote Desktop
connections are permitted.
• The remote computer must be running a compatible version of Microsoft
Windows and must be connected to the Internet or on a local area
network.
• The remote computer must have the Remote Desktop Connection client
software installed. The remote computer is called the client.
• Both computers must be connected to the Internet through a Virtual
Private Network (VPN).
• Appropriate user accounts and permissions configured on the remote
Windows XP Professional host to allow remote access.
If your client computer is not connected to the host computer through a
VPN, you need to use the actual IP address of the host computer instead of
the computer name.
Installing Remote Desktop Client Software
The Remote Desktop Client software is installed by default on computers
running Windows XP.
Calling From a Remote Location
1 Use the public IP address, as assigned by the ISP, or fully qualified domain
name of the computer or router/NAT/firewall.
If the firewall/NAT/router is configured correctly, the call will be
successfully passed to the appropriate computer.
2 If the ISP assigns a dynamic IP address, then another solution is to set up
an account with one of the dynamic naming services that map a fully
qualified domain name to the IP.
