Ask for Remote Assistance /host name issue

[Guest]

I cannot receive (ask) "remote assistance" but have no trouble
receiving a request for remote assistance and logging onto computers.
I have xp home & trying to connect to xp professional (also tried xp
home with same results). I have dial up and the xp professional has
cable. Both have firewalls and both have been disabled.
We are trying to connect through windows messenger. (email has also
failed).
I get no messages saying it cannot connect but the xp prof states
that "cannot resolve host name" I cannot find anything about the
message in microsofts knowlege base. Any help would be appreciated.
Thanks in advance

If the requesting PC is behind a NAT router, then Remote Assistance requests
will fail unless the router has UPnP support enabled, and the requesting PC
has an Exception enabled in Windows Firewall for "UPnP framework".
