ISSUE -- Vista RTM + Cisco VPN + RDC = No RDC

Good Day.

I have Vista RTM running on an Tecra M5 and so far no issues until this one...

The Cisco VPN Client v4.8.01.0410 (Beta) is installed and am trying to
access a Terminal Server. I can connect via Cisco just fine however I cannot
get a Login Prompt on the TS. The TS background appears but after about 15
seconds I receive an error that my Remote Desktop Connection has ended.

I have connected using the RDC with other TS’s and had no issue however when
the Cisco is put in the middle my problem starts.

If I run the same test using XP and the Cisco VPN I have no issues. I also
had no issues with Vista RC2.

Any ideas?
