Remote Desktop Connection isn’t exactly easy to set up when compared to services such as VNC, Team Viewer, or Join.Me, which also offer remote access to PCs. If all you want is to view files on your hard drive, or help out friends and relatives with remote support, then we’d definitely recommend these solutions as friendlier alternatives.

And with cloud storage being so affordable these days, not to mention cross platform, we’d also suggest that keeping your files on one of these services is an easier and more convenient way to embrace the online world in which we live. Remote Desktop Connection has some strong features, but in many cases we would be surprised if those mentioned above wouldn’t do the job and save you a few grey hairs in the process.

How to use Remote Desktop Connection in Windows 10: Find the IP address

Before you can connect to your target PC you’ll need to know its IP address so that it can be found on the network. To do this hold down the Windows key and press R. In the box that appears type cmd and press enter. In the terminal windows that appears type ipconfig and press enter. You’ll see a range of information appear, but the one you want is IPv4 Address.

The IPv4 address will allow you to access the PC on a local network, but if you want to access it from a WAN (ie if you’re at work and want to dial home) then open up a browser and in the address bar type in whatismyipaddress then make a note of the address.

How to use Remote Desktop Connection in Windows 10: Connect to a PC over the internet

Things are a little more complicated if you want to access your PC when you're not on a local network. First, you’ll need to make sure the Windows firewall isn't blocking Remote Desktop. You can check this by opening up the Windows Firewall section of the Control Panel and selecting Allow apps to communicate through Windows Firewall.

Next you’ll need to configure your router so that it knows the correct addresses for your  computers (do this using the Default Gateway and WAN settings you wrote down previously), and enable the Port Forward setting so that it points at Port 3389. As router settings are different on every router, you should read our guide on How to forward ports on your router to make sense of it all.

It’s worth bearing in mind that if you intend to use the internet to connect to your PC on a regular basis, the external (WAN) IP address is subject to change. To avoid having to rediscover the address every time this happens, subscribe to a dynamic DNS service such as no-ip.com, as this gives you a memorable domain name to which you can connect, and will keep track of any changes to your external IP address. Many routers have built-in support for dynamic DNS, so have a look in your manual and select one of the services supported by your router.

With all of this completed you should now be able to open the Windows Start Menu, search for Remote Desktop, select Remote Desktop Connection, then in the box that appear type the IP address and click Connect. Enter your username and password, then you should have full access to the target PC.
