I have a local network with some PCs using internal IPs of type 192.168.0.x and some PCs with real IPs running XP. The problem is that I can't access the PCs with the internal IPs from the XPs. If I change XPs IP to internal IP it then works, but I want to have the XPs using real IPs. It is not because Netbui is not installed. It is already. The problem is with the different network segmentations.
