I've tried looking up an answer, but all the "tutorials" are non-specific in the one area I don't understand.
What I want to do is be able to use my Microsoft Surface tablet from anywhere I have internet, and use it to control my Windows 8 PC. That does seem to be the purpose of the Remote Desktop app, correct? Now, I have enabled Remote desktop connections in the system settings, and have the app installed on my surface, and they are both using the same Live ID, but the next step listed is just 'Type the computer's name or IP address' and none of those tutorials explain how I know exactly what either of those things is. I've tried entering the name I gave the computer, which was also listed on the window that I got to the Remote Connection settings from, but nothing happened, and to be honest I don't know why it would. There are a huge number of computers on the internet and I didn't see anything that would prevent me from sharing a name with some other device. On the other hand, rather than too many results the app can't find any.
I then figured I'd try an IP address, but for some reason whatismyip.com said it didn't know. This is probably something set on the router, and possibly the reason that the previous attempt didn't work, but I don't have control of the router so if that's the case then I'd need an alternate solution.
I'll also accept some other software that would make this easier, say by just logging in from both devices and selecting from a list, but I have to be able to control it from a Windows RT device (I don't need to go the other direction, and I don't think that's supported anyway). Feel free to just suggest something even if you don't know it'll get around the problem, it's not necessarily reproducible on your system so the only way to know is for me to try it out.
