I've set up Remote Desktop web connection and it works well when I use it
using a local ip address within the network. However when I connect from
outside the network, I get to the main screen where the Active X loads. when
I click connect though, after some time I get an error message saying that
maybe remote desktop connection is not enabled on the machine or there is
some network problem and I should try again later. I use an Aztech DSL turbo
900 router which has NAT enabled and I've tried opening up all the ports in
the posts. I suspect the problem lies with the router configuration. Can
anyone help?
 
You need both TCP Port 80 (IIS) and TCP Port 3389 (Remote Desktop) forwarded through the router to
the static LAN IP of the IIS server and PC your trying to connect to. Call using the public IP of
the router, ie. the IP assigned by your ISP.

Thanks, but I've already done that. I noticed a strange thing though, (after
I posted) if I leave the server name blank and click on connect, a black
screen opens with the external ip of my router on the title. when I login on
the next screen using an account on the machine where IIS is running, I can
use it normally. But I cant connect to any other machine on my network even
though remote desktop is enabled on them. Do I need to set up all the sytems
as hosts using different port numbers for IIS for each one of them? That
would be a big task.
 
The web based method, using IIS, still requires you to port forward the RDP protocol to each PC
through the router. You simply can not get around that. You then need to use Jeffrey Randow's
(MS-MVP) modified default.htm file on the IIS server so you can dynamically change the port your
calling with...

Make a backup of the original default.htm file first just to be safe...

As you can see, using the web based method adds complexity to the process. It may be easier for you
to simply access the PCs via either a VPN or SSH tunnel. Personally I use the SSH tunnel method to
access one or more XP Pro/Home boxes using either XP Pro Remote Desktop or UltraVNC for XP Home
machines...

Thanks Sooner, I'll try that out & get back.

make sure the DNS servers on the TSServer are set to the correct address,
and not just pointing to the router.
