Thanks for that Robhogg - got into my Linux box real easy however *this* message popped up when I tried to access the PC:
Connecting to Server
Connecting to smb://blah blah
"The operation cannot be completed because one or more required items cannot be found (Error code -43)"
<Try again> <Cancel>
I have fossicked around in my PC and disconnected the firewall (not that it was doing much), made sure that all shared files are still shared (not changed) and added a user password just in case the mac could not handle a null.
So close, yet so far...
