I've got a peer to peer network. DHCP assigned IP addresses thru a router. (also have 3 hubs) Operating systems range from Win98 to WinXP Pro. Two work groups. (a and b for simplicity) if I change my workgroup to b I can browse that workgroup and a few pc's in workgroup a (but not all of them on workgroup a) if I change my workgroup to a I can not browse anything. However, if I type in the address or use one of the shortcuts to the shared location, it works just fine. Why can't I browse while under the group a?? I've tried removing TCP/IP and resinstalling it. Tried restarting the Router. Tried assigning a static IP. Didn't work. Not sure what else to try.
