I am trying to connect to a PC in another state via Remote Desktop. Heres what I've done so far: 1)Set up to allow RDP connection to the computer I want to connect to. 2)Disabled Firewall and Network Security software. 3)Setup IP address forwarders on the router. To forward port 3389 to the IP address of the computer I want to connect to, on both TCP and UDP. I couldn't do single port forwarding with that router so I had to use port range, and i just did start = 3389 and end is 3389. 4) Acquired the external IP address of the computer I want to connect to via whatismyip.com Now after doing all of that. I go to RDP and type in that external IP address, and it still tells me unable to connect. Any help would be greatly appreciated.

Are your trying to connect to that PC from within the same local network over the internet back into the same local network. This mostly woun't work.

No I'm trying to connect from one network, to a separate unrelated network over the internet. If this doesn't work is there a way to set it up with a different program? Maybe TightVNC or something of the sort?

Did you enable Remote Desktop connections and the Terminal Server Service and added your account login to the Remote Users Group on the Remote machine? Is the remote machine behind a firewall that requires VPN. Life's more painless for the brainless.

I did not add any users to the Remote Users Group, I will be logging in as the only user setup on that computer, which will by default be the local admin account, I think. I didn't do anything with terminal server services. I'm not sure Terminal Server Services are available on a windows xp home PC. Lastly no, it isn't behind a firewall that requires VPN. It's not behind a firewall at all.

Have your checked, whether the port is reachable from the internet? Check this on the PC, you'd like to connect to and check for the port 3389. http://www.auditmypc.com
