I get the message: 'Remote Assistance connection could not be established because the remote host name could not be resolved.' - What does that mean?

One common problem connecting with Remote Assistance typically involves a router 'getting in the way'.

Essentially it just means that remote assistance didn't get a response from the target computer. The most likely cause in home scenarios is that there's a router in the way at the remote site. For Remote assistance to work, port 3389 must be forwarded on that router to the target computer's internal IP address.

The accepting computer has to allow remote access, under control panel, system, remote. Hope this helps. Also, if using vista, you can access an xp installed computer, but not the other way around.
