VNC not working the same way

[Richard Keating]

I have VNC v4 running on a server that is on the back side of a Linksys. 
Yes, it has forwarding on. 

I have VNC v4 installed at work, and at home.  From work, I put in the 
IP and the authentication screen opens, I put in the password and the 
screen opens, but remains black.  Hmm, must be something on the server I 
surmise.

I go home and point the same version VNC to it, and voila, it opens and 
I see the white logon screen (Win2K Server).

So, I figure it is something with screen turned off, or something like that.

So, I fixed home setup so I can reach home from work  I can reach home 
from work (all is well)  I try to reach the server in question from the 
VNC session at home and all works.  I try it from the VNC session at 
work, and black screen, no activity.

VNC is getting to my home computer from work, letting me start a session 
to the server and all works.

What should I be looking for to fix the VNC session from work to the server?

Session summary below

Work----------->Win2K server  (black screen - no response after 
authentication)
Home----------->Win2K server (good)
