Remote assistance

[Guest]

I'm trying to use remote assistance between my home pc and my networked
office pc. I've opened port 3389 on the firewall at each end. When
accepting the invitation using Outlook, I get a messeage: Remote Assistance
connection could not be established because the remote host name could not be
resolved. Please try again.

All help appreciated.

that means that the name of the remote machine is not known to the machine
you are trying to connect from. you must either fully qualify the machine
name if it has a valid domain name or connect using the ip address.

Forgive my ignorance but does this mean I would need to set up a VPN
connection first?

not if your routers are smart enough to forward the incoming connection to
the remote machine. though a vpn would make it easier since that would make
the two machines think they are on the same network.
