Cisco VPN Client and Windows 7

So I was searching today for something specific to the Cisco IP Communicator software phone version of the Cisco IP 7941 to see if there is a way to make it work nice with Windows 7, but in the process I found a lot of threads and blog entries about problems with the Cisco VPN client causing BSOD’s with ndis.sys.

I’d just like to say that I’ve got the Cisco VPN client installed on my Windows 7 Build 7000 machine without any issues. I can connect and disconnect as many times as I like without issue.

This is actually better than the experience in Windows Vista where the Cisco Virtual Network Adapter for the tunnel kept failing meaning after every connect/disconnect cycle I would have to reboot to get the adapter going again before being able to connect again.

This hit me worst at home if I roamed between my two Wireless AP’s where the WPA2-PSK authentication takes a little bit of time and the tunnel would drop during the roam.

In a nutshell…..Cisco VPN client just works in Windows 7, just like it should do.
