How Computers talk to each other.

is the fact that I have Norton 2010 complete with Firewall, anti-virus etc likely to be a problem?

Richard --

Haven't used Norton for a long time, so am not familiar with its firewall constraints. The only potential issue there could be with Remote Desktop. Usually the firewalls are already configured to allow Remote Desktop both ways, but, if not, that is a change you may need to make. Rather than speculate now, let's wait and see. If you have a problem with Remote Desktop, just ask.

Good luck, and do let us know how it goes.

Take care,
Russ
