sounds like an xp home issue with netbios… i’m guessing the home machine is the wrong node type… peer to peer node is not correct, type ipconfig /all and see… peer to peer relies on netbios … try nbtstat -c for the remote cache names
i dont know… sounds like typical netbios crap, but if you can’t ping then something networking is jacked up… please tell me your pinging by ip right? otherwise it’s just because xphome relies on netbios for name translation and the wrong netwrok node type will not propagate names to a network.
