Well, I'm not sure what problem you're having, but you can try: ssh -L
5901:localhost:5900 <win2k host>.  It will probably give you the same
results, but it will rule out any host naming issues.

Try turning debugging on for the encrypted tunnel, as follows: ssh -v -v
-L 5901:localhost:5900 <win2k host>

You'll see a whole lot of debugging info when you first sign in with
SSH, and that can all be ignored.  When you attempt to create a
connection over the tunnel, however, you will be given quite a bit of
additional debugging information pertinent to the tunnel.  It can help
in cases such as this.


Hope this helps!
