When you receive an invitation from an Internet user whose computer is behind a router or firewall, the IP sent to you is the private IP behind the router or firewall. To fix this issue, 1) use notepad to open the invitation to change the private ip to the public ip which may be the router or firewall's ip. 2) Use Windows Messenger to establish the Remote Assistance session.

Have you done remote assistance on this machine before? I'm guessing they are probably behind a router and NAT-ted out. Remote assistance requires any firewall to allow outbound TCP port 3398.

Here's a good article on Inform-IT for Remote Assistance troubleshooting and general requirements (Make sure you read the comments, it deals with your exact issue):

Here's another article from Windows XP expert zone that sums up how to port forward the remote assistance from the public IP through the router to the workstation in need.
