Since Cisco Systems VPN Client does not work properly with mobile broadband on Windows 7, we've been successfully using Citrix's DNE Update to fix this for about 6 months. All of a sudden, machines with the DNE Update stopped working properly over VPN (whether using mobile broadband or not). The only fix is to unbind the DNE Lightweight driver from your network adapters, uninstall the DNE Update and reinstall the VPN Client. However, then you cannot use an aircard with VPN as the DNE Update was the fix.
Symptoms of the VPN issues with DNE Update:
-web pages displaying garbled
-internal web pages not rendering at all
-remote connectivity not working (VNC)
-RDP connects then crashes with data encryption errors
The only change that I can identify on our machines and in our environment would be Windows updates, but I've been unable to identify which one might have caused the problem.
Has anyone encountered this issue and found a fix? Does anyone know of another reliable fix for VPN Client to work with Windows 7 and aircards?
We're looking at moving to another VPN solution but that will take time and we need a more immediate solution.
Thanks in advance for your help.
Tony
