update to this problem.

i formatted the "host computer" but now the problems are even stranger..
The computers can ping each other by name and number. The Host computer can view files on the "client" one, but not vice versa, there is an access denied error.
Client p.c can access the internet, but only certain sites and only by using firefox. Internet explorer just gives a "page cannot be displaye error"
I try to do net view \\computername but the client pc gives a system error 5 message, where as the host p.c can do it no problem.
I have run through all the access rights and cannot see any problems.

if i do ipconfig /all i get this



C:\Documents and Settings\lisa>ipconfig /all
