According the Routers LAN>DCHP clientlist only Computer B and the XBox are allocated IP Addresses (192.168.2.3 and 192.168.2.4). Computer A can see the files on Computer B; However, when Computer B tries to access the network, it cannot see Computer A and simply gets the "access to MSHOME not permitted, see network administrator, etc".
I know Computer A is allocated 192.168.2.2, so why does this not show on the clientlist and, is this the reason that Computer B can't see it's files?
Both computers can access the internet. The only problem is Comp B being able to access Comp A's files and directories.
I hope I've explained this thoroughtly enough for someone to be able to help?
