OK, I think I may have found out why the problem exists.

Seems the PC's that were on the D-Link at one client were
all on SP1 for all ports 3390 and up, and 3389 was on a pc
with SP2. I'll get to the point in a min. Can connect to
ALL PC's OK.

The other clients are all running SP2 (at other locations),
and the only ones I have success getting into are port 3389
as 3390 and up, cannot connect.

All port forwarding is configured correctly on all routers.

The problem is even though the registry has been modified
on the PCs requiring an optional port, the windows firewall
is on on the SP2 PC's. If you go into the firewall
settings, Remote Desktop and Remote Assistance are all
checked, but they refer to Port 3389. There is no way to
delete the entry or modify the port from there (firewall),
just enable or disable. Sure, I tried adding RDP-Port
3390, but it won't allow connects. Sure, I can turn off
the firewall, but I don't want to.

What I need to do is modify the firewall settings for RDP
to allow Port 3390, not 3389. Can this be done? Or do I
forward in the router (UPnP Port Forwarding), and if so, is
it 3390 --> 3389 or 3389 -->3390?

Be aware that the router had 'normal' port forwarding
(APP-port port tcp or udp ip add (nat) enable or disable
(check), and then there is the UPnP port forwarding.

Which configuration to use, or do I modify the firewall
port, and if so how?
