Remote Desktop doesn't work

[Mona_LIsa]

I have the following problem: At home I have a RD connectection to a
computer (ip-adres starts with 85.203) which works. I can login on that
computer. When I try a remote desktop to a computer with a IP-adres
which starts with 192.168, I can't connect. I get the follwing message
"The client could not connect to the remote computer. Computer
connections might not be enabled....." What may be the problem?
When I am at the office I can connect to both computers. If I am at
home I can connect to the second computer through the first one. But I
want to know what the problem can be. I have a wireless speedtouch
modem. I have given my laptop a permentent IP-adress, in my
NAT-settings I have opened the ports 3389 en 3390. In windows firewall
exceptions settings I have checked the Remote desktop box. What else
could I do to make it work?

Thanks...

We need more details. Where do you try to connect to 192.168? In the same subnet or from the Internet?

I'm not sure what you mean? I'm connected to the internet. I think that
the computer with IIP-adres 85.203 is configured as a webserver. The
other one isn't. I think the webserver is in the same domain as the
computer with IP-adres 192.168.

192.168 is a private IP address and only accessible from within that private
subnet.

In other words - the reason you can remote into the server with the external
IP is because it has an *external IP*.
From that machine you can get to the machine with the private IP because the
server likely has an IP within the private subnet as well as the external
one (and/or hands them out even.)

If you want to get to the machine with the private only IP --> you will have
to properly configure your router/NAT device/Server handing out the IPs to
forward a port request to that machine. You will likely want to change the
remote desktop listening port on that machine so you do not intefere with
other machines on the network/confuse the situation more.

192.168.x.x is private IP address. No one from the Internet access it for your security.
