I am onsite trying resolve an issue. I have two new XP boxes; on one there is a small switch with a WAP plugged into that. The other PC is wireless. I installed a workgroup, shared the PC's. Everything was fine. I then installed a Verizon Broadband Aircard. Went in fine, connects to the internet; turned on ICS. Now my network is slightly hosed. I can ping each machine from the other, but all I get back is the IP address, then the Ping's time out. The other PC actually detects the broadband card and it's state, whether connected or disconnected, but if I open a browser on that machine, I get nothing.
I have disables firewall monitoring on both PCs, even in the advanced tab. I'm thinking the conflict may be between the WAP and the Aircard assigning IP's, but I'm not sure.
Urgent Help is an understatement.
