I don't understand if the network looks like this:

Your PC ----->  Netsceen -----> Internet ------> Terminal Server

Or do you mean the terminal server is behind the netscreen?

Internet -----> Netsceen ----> Terminal Server

Anyway, you need make sure that port 3389 is unblocked the whole way and forwarded to the server at the server end.

The problem is My PC ----->Internet------>Netscreen-------->W2K Terminal server.
I'll try again, but there is something I'm missing in the Netscreen config. I can TS just fine behind the a 192.x.x.x space.

Okay, this is all about punching a hole in the Netscreen in NAT mode.....I hope I never run into one of these things again....

If you are sharing an IP address (nat mode), you need to configure the netscreen for port forwarding, from the external address (ie. the one from your isp) on port 3389 to the private ip of your server (eg on port 3389.

You might need to connect up the the com port of the netscreen to get to the CLI.
