UPDATE:
Earlier I sat at my server, and sucessfully managed to connect to my own pc (the 1 with the Nvidia in it) and it worked perfectly, so the problem lies on my pc somewhere, typical really as this ASROCK motherboard has been nothing but bloody trouble since I got the thing!
So saving all my pennies for a nice new AM2 motherboard for myself
Then its a new router I need as this BT Home hub is complete pants!
