server disconnect means what?

Check to make sure that vnc is running on a specific port one winnt.  By
default it is set to first available wich is 0 not 1 like linux.

I just setup this same scenerio last week.

Here is how I set it up:

lcli -> fw -> ... -> mfw -> w2k

    lcli is a linux machine using 'ssh -lroot -L40000:w2k:5901
mfw.blah.blah.com'
        also run 'vncviewer -encodings "copyrect hextile" localhost:40000'

        This also works with win2k as a client using terraterm and ttssh.


    fw is a linux firewall/gateway that is very restrictive

    mfw is a linux masquerading firewall with sshd running on it

    w2k is a windows 2000 machine with vnc running on port 5901
        (note: w2k is lookedup by mfw not fw, so it uses the 10.0.0.1
address)
