Remote Desktop will not work on internal network

Thanks to George for the suggestion. That's good port probing test. Just a minor add. You will get nothing if port is open. Though if you'll connect to http service port and sent Return, you'll receive a code 400 on your screen. If port is closed you'll receive message that connect was failed. For cases when you have firewall installed between your LAN and outside network there is a trick how to manage to get service working on one server within a LAN seen from the outside. You can setup a port forwarding service. For example we use desktop management solution from Scriptlogic that we use not only for managing desktop clients throughout LAN but also for remote management. [url=http://www.scriptlogic.com]Desktop Authority[/url] has a very nice remote management feature and it had to be a shame if we would not use it. So we managed to build port-forwarding and redirected port on a firewall to a port on our server where sits our management service. That's was very helpful for us because now we can watch for the state and manage environment even during the vacations with notebook and browser. The best feature is that it has group policy and active directory management, so the process of user management is that as simple as it is normally within ADU&C and GMPC snap-ins.

2 Computers, and a Linksys router, all firewalls are turned off, all antivirus is turned off, port 3389 is forwarded on the router to the desktop pc

I'm just trying to remote to another computer within the home network

DO you have a page that says that oin Microsoft's site by chance? Thanks
