Q: How to fix the error "Remote Assistance connection could not be
established because the remote host name could not be resolved"?
A: 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. So that you can't access the computer. To fix this
issue, 1) edit the invitation IP address. 2) Use Windows Messenger to
establish the Remote Assistance session.
