Well, problem is fixed... read on for more information.

No, I understand the principle behind the VPN tunnel.  I know there are
basically 2 nic adapters, one real and one virtual.
The problem lies in the implementation of VNC in NT 4.0 vs NT 5.1 (XP).

On one laptop (XP), I run a VNC server when I am connected to my Cisco VPN
client.  A mouseover of the VNC Server systray icon displays both my
private IP (VPN) and my public IP.
On the other laptop (NT), in the same scenario... I am running a VNC
server after I connect via my Cisco VPN client.  The mouseover of the VNC
Server icon in the systray only displays my public IP, no private IP.
We use Remote Assistance for our XP clients and pcAnywhere for our NT
clients.  This guy had NT but for some reason the baseload he got didn't
have pcAnywhere so I was looking for an alternative.  We use the Blackice
firewall client on all our laptops for protection but have ports enabled
for both pcAnywhere and Remote Assistance to work when connected with our
VPN client.  I had quite simply forgotten that fact since I never have to
disable the firewall when our users are connected to VPN.
Long story short, disable blackice and VNC works like a charm.  Made no
difference that the private IP wasn't being displayed on mouseover...
still detected and advertised on all IPs.
To just make a quick u-turn.  Is there some type of barebones VNC setup
that we (I) could use here at work when we run into problems with
pcAnywhere/Remote Assistance?  I know that I can make a setup answer file
to deploy with the package but I'm really looking for some type of
barebones install that installs the server only (not as a service, client,
icons, and even some default port changes, etc).
Thanks again for all your thoughts.
