VNC NTServer VPN

I am trying to use VNC to access a Windows NT Server (Backup Domain
Controller, BDC). I am accessing the BDC via an all Microsoft VPN. I have RAS
on the Server and use the PPTP protocol to connect. I can connect to the
server (and have been doing this for some time now).

Here is my setup.
Corporate- NT Server, BDC running behind a Linksys BEFSR41 nat router. Public
IP on the Wan side of the Linksys router. Forwarding ports 80, 25, 110, and
1723 (for Linksys to work with VPN) to the 192.168.xxx.xxx NT BDC.

Remote- NT Workstation, running behind a Linksys BEFSR41 nat router, dynamic
public IP (which has not changed in months).

The Problem:
I have loaded WinVNC onto that server and can use the Win 98 client viewer
while on the local LAN. However, when on the remote NT Workstation I can
successfully connect to Corporate, but I cannot successfully run the WinNT VNC
client. I can enter the IP address of the remote machine, I get prompted for a
password and the remote screen initiates, then turns all black, and then shuts
down.

Question:
Has anyone successfully connected VNC via a VPN tunnel of any type, and
specifically the type described above.

Thank you in advance.
