A number of users reported seeing the 0x104 error on the remote desktop connection under Windows 10. This can be an extremely frustrating problem because many people around the world need to remotely access their work servers and use this feature to collect or access data from the company they work for.

Remote Desktop is a program or feature of the operating system that allows a user to connect to a computer in another location, see the desktop of that computer and interact with it as if it were local. It is particularly useful in the workplace, both at home and in the office. You can access your computer when you are at home, at work or traveling.

One of the most common errors with Remote Desktop is Remote Desktop Error 0x104. The message is as follows: “We couldn’t connect to the remote PC because the PC can’t be found. Please provide the fully-qualified name or the IP address of the remote PC, and then try again.”

There are several reasons for the Remote Desktop 0x104 error. One of them is if you have a custom DNS setting. These can prevent connection, so it is recommended to delete these custom settings. Your port may also be blocked by the firewall. If this is the case, be sure to allow the port via the Windows firewall to avoid the error code. In some cases, network discovery is disabled, so try to enable it again.

The good news is that there are methods you can use to correct the error code. Take a look at the following suggestions to see which ones are right for you.
