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 BSODâ€™s with ndis.sys.
Iâ€™d just like to say that Iâ€™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 APâ€™s where the WPA2-PSK authentication takes a little bit of time and the tunnel would drop during the roam.
In a nutshellâ€¦..Cisco VPN client just works in Windows 7, just like it should do.
