Hi:
Problem solved - I worked out that it was likely a Vista - XP comms issue and it was. I booted my old P4 machine in my room and found my internet dongle (this machine runs XP family). I then booted the server which runs XP pro and as I had done all the drive sharing things before it worked automatically.
This really, really annoys me, I knew I had done everything right and was literally sweating over this problem earlier in the summer, doubting myself etc. However, it now works fine.
My next question is this - if I connect a non-network enabled printer to the server by standard USB and share this printer, should I be able to print from this remotely from the computer in my room or do I need to have a printer plugged by ethernet into the router directly.
My next project is to get my slingbox setup which is hopefully going to be very easy.
Thanks everyone for your help
Graham
