VPN client kills WinXP when using wirelss EAp-TLS

I've run in to a problem since upgrading to SP 1 for WinXP. I use EAP-TLS to authenticate to an IAS radius server when using the Aironet 350 card. I am NOT using the Aironet utility, using the native XP utility. After installing SP1 anytime that I insert the wireless card, I get an BSOD on the XP system. Without the card inserted no problem. Anyone have any ideas?

Probably should have posted this question to the wireless-mobility forum.

Otherwise, I suggest you open a case, there may be incompatibility with the aironet drivers and sp1.

Forgot to mention. This only happens when the Cisco VPN client is installed on the system. I will also post to the Wireless-Mobility, but it doesn't happen when the VPN client is removed.

Re: VPN client kills WinXP when using wirelss EAp-TLS

Similar problem is discussed before, see the link provided below. Our experience is worst, we have to re-install the entire XP system !! This is happen on an IBM notebook with a pre-installed WinXP and Cisco Wireless. Seems like Cisco Aironet driver and Cisco VPN client driver are not able to be installed in the same system which the OS is Windows XP. Hope that Cisco would address this problem.

See the link below for a workaround provided by John Gudmann:

Engel,

Thanks for the information. I am glad to see that I am not alone. I don't have a MAC-bridge in the network connections, but the systems I am having problems with are IBM T30s using the Aironet driver. Since the Cisco VPN client is essentially a shim in the TCP/IP stack, I think there is a problem with some DLL that changed with XP SP1. Anyway, I am still looking for an alternative because my customers don't want to buy ACS to do authentication.

Thanks,

Tony...
