SSH Tunnelling with WinVNC?

[drkestrel]

I have the following set up

VNC Server:
-Runningg Windows 2000 Professional SP4
-Open SSH (as a Windows Service)
-RealVNC run as a Windows Service (password set whilst user Myadmin is logged on)

User set up:
-Myadmin -Administrator group
-Mylocal -restricted user

Following regiistry key set and VNC service restarted:

HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3\AllowLoopback=1
HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3\LoopbackOnly=1

VNC Client:
-Real VNC Client
-Open SSH client
-Windows XP Professional SP2

The following works:
Setting 1:
1) Myadmin logs on to Win2K machine
2) client issue sshh -C -L:5901:127.0.0.1:5900 mylocal@Server'sIP
3) enter mylocal's Windows password on SSH
4) Enter WinVNC's password when prompted
5) connected but slow connection

The following does not quite work:
Setting 2:
1) Mylocal logs on to Win2K machine
2) client issue sshh -C -L:5901:127.0.0.1:5900 mylocal@Server'sIP
3) enter mylocal's Windows password on SSH
4) Have to enter an OLD WinVNC password!! (no WinVNC password was set whilst
logged on as mylocal), have to use the first WinVNC password set whilst logged on as myadmin
5) after successful authentication, all I get is a blank black screen on the viewer, connection info indicate a line speed of 0kbit/s, Depth level=8 (network monitor indicate no network activity), but SSH appears to be
working, on the terminal I couldd CD into different directories and do dir, etc.

How could I get VNC/SSH working together on setting 2 above?
