When the Windows VPN Client is running I am unable to start the Unified CallConnector. It appears that somehow the VPN client interferes with the UCC license check, so that the UCC is never able to verify its license. I can start the UCC with no trouble over a hardware VPN, or if the VPN Client is not running. This is on Windows Vista with the most recent versions of both the UCC and VPN Client. Am I missing something?
