You are a little off. This setting is only an alternate setting. If it is unable to use the primary Windows XP will attempt to use these alternate settings. This does not in any way allow you to set multiple IPs on one NIC. Umm i dont think that is true, I am doing my cert 4 in network management, as I said, I built a win2k server at tafe, which was on a different IP range and subnet range to the rest of the tafe network, so I assigned a secondary IP address to the one nic that was in the pc so it could communicate with the tafe network and the proxy, and I was able to get net access working using this configuration...and also see shares and stuff on the tafe network as well as the network we were building... You guys are incredibly right .... I will give this a try .... Thanks for the feedback ... UI - PS: checked in windows 2000, and you can add aditional Ip numbers.
