I have just installed a new PC on my home network and am unable to see the rest of the network. I have a router serving as a DHCP server and used for internet access. I had 2 PC on the network before adding the new unit and they function perfectly. The first two units are running Windows XP Pro and the new unit is running XP Home. When setting up the new PC I used the network wizard, as I have done since switching to XP. The new PC can ping the other computers but when attempting to ping the new PC from on ot the other units it will time out. When checking workgroup PC's on one of the old units they recognize the new unit but can not access the new unit. When checking for workgroup PC's from the new unit I get an error network is not available. There is no firewall running on the new PC, and the new PC can access the internet through the router. All indications are that operating is not allowing the new system to access the workgroup but I have gone through the settings several times and reran the network wizard several times with no help. I have also manually set the IP addresses in an attempt to get the unit to talk to the others with no help. I am looking for ideas on what I am missing or other areas to check to solve this problem.
