Thanks for the help, the websites are helping a lot.
The server computer is in a completely different time zone so I have to wait for a good time before I can initiate anything. However I did get some specs from the server setup.
The machine is running windows 7 32 bit and is behind a linksys wrt160n v2. I have just done some searching and have seen problems with that router, so hopefully I'll be able to resolve it soon.
The Client computer is also running Windows 7 32 bit and is behind a very old I/O Data NP B8RL router.
I'll keep you informed.
