Tried to help a friend using Remote Assistance Windows XP Pro, using windows messenger. Got as far as invitation had been accepted, actual connection failed with an error message saying something about'....host name cannot be resolved......'

My PC is behind a netgear rp614v2 router. Wonder if it is the router that is causing the proble. I also had opened port 3889, but still failed.

Has anyone got any suggestions?
