I have an ATT aircard which ceases to function properly when the laptop is joined to the domain. It will acquire a dhcp address etc and the connection manager shows connected and is sending but I am receiving nothing. It seems as though it is being blocked but I've checked popup blocker, group policy, anti-virus, and firewall. That doesn't mean i haven't missed something on any of those. Any suggestions ou there?

Are the network settings you get from DHCP correct to work onthat network? Is it a DNS issue? How far can you ping/tracert to?

Can't ping anything. I've disabled onboard wireless, firewall and anti-virus. The aircard ceases to function after the laptop has been joined to the domain.

Thanks for replying.
No VPN is setup and the aircard acquires a DHCP lease ok from ATT but will not receive anything.

When installing the card, it is important how you install it. If the laptop has a built in wireless card, you may have to disable it when making the WAN/LAN connection. I work with a lot of Verizon cards, and in every case I have had to disable the wireless (FN F2 on a Dell)in order to use the Wireless Network setting. If you are using the card internally (inside your WAN) you may need to do that. Outside the WAN, you will need to also use your VPN client to log in. Sounds like you are not authenticating. Hope that helps.

The connection software only comes in one flavor. It only fails after joining to the domain.

Are you albe to log into the domain and are you being disconnected after you do? You may need to talk to your Network Admin to see if there are any other protections that could be kicking you off. Also, test the card in another laptop to eliminate the possibility that it could be the card. I have had more than one turn out to be a lemon. :)
If you could provide more detail on how you connect, where, and what happens at each step that could also be helpful. Check your event log for any security or application errors that may be recorded and share them with us. We might be able to pin point the issue for you. :)
