I'm almost 100% positive that this is an easy 5 minute fix and I'm just overlooking something minor but so far I'm stumped. I manage about 100 PCs throughout my current location and recently I upgraded the WinXP PCs that have the WUSB54G v4s to the 220.127.116.11 driver. After doing this I wanted to go into the advanced settings on the TCP/IP properties and check a few things, Enable NetBIOS over TCP/IP since they are all using static IP addresses now, etc. It was business as usual on every PC until I started working on the one PC (out of the 6 updated at this time) that can not reach anything on the network when it establishes the wireless connection. It will connect .... but "the internet cannot be found". It will never obtain an IP address from the DHCP server if I have it set to auto assign the IP/DNS. If I assign one it will show that it's connected but nothing on the network is reachable at all. The strangest thing is that there is no advanced button on the TCP/IP properties page. It just has the second tab at the top to setup an alternate IP address (as if you were using a laptop and went between locations but didn't want to manually switch the IP every time) I know I've seen this somewhere before but I can not remember why it is like that or what is causing it. I almost remember the advanced button missing because a PC is lacking some update but this computer is all up to date. I can't find another PC in our network that has the same TCP/IP settings page. I've tried searching all around but have come up empty handed. Is the key to solving this in one of the "net" commands for XP? I'm heading in that direction as soon as this is posted. Any help would be greatly appreciated. I know one of you has seen this or knows what I'm talking about. I'm surprised it's not an issue found on google more often.
