HWGA with network probs.

[Goldminer]

Sorry if this has been asked hundreds of times before but I have had a look in old threads. Just got cable Broadband with set top modem and bought a 4 way DSL/Cable router to share the internet connection. Works a dream for the Broadband but I am not able to share files now. The 2 computers are running Windows XP home and Windows me. Ran the set up wizard on both and they both seem to go through the motions and the xp machine recognises there is another computer on the network(and gets its name right) but the me machine has no access to the network. When I run a diagnostic it says that I may have 2 computers with the same name. I then renamed them but with no success.:mad:
Any advice gratefully received!
