I have several pcs connected to my lan at home. I often share files/printers between them. I am running XP pro on all machines. Since I have installed a 3Com 3CR858-91 Cable/DSL router I have problems with sharing files and printers. No problems with internet access to any of the computers, just not able to share files or even view computers in my work group. If I remove the router, connect directly to the Westel modem and reset for the modem to provide DHCP all works fine. I have not had much luck finding help with this issue. Any hints will be most appreciated. Thanks
