I have 2 winxp pro computers hooked up together through a wireless router, but I am using my 10/100 connection. I have my cable modem also hooked up to the router, and have the router config w/dhcp. My router's ip is 192.168.0.1, my main computer has been given 192.168.0.100, and my second pc has been given 192.168.0.101. I have each computer assigned to the same workgroup name and fully rebooted. Each computer tcp/ip is config for auto. I am able to ping each other's ip address, but not name and can't find each other's folders on the network. Sounds like DNS and smells like DNS, but I have no DNS server. It's a simple workgroup. I do believe my Cable isp provides DNS service. Is that the problem?
