Remote Desktop not connecting on Windows 11: how to fix it

Remote Desktop says it can’t connect to the remote computer? Here’s how to fix it: Windows edition, turning it on, user permissions, port 3389, the firewall and credentials.

When you try to reach another computer with Remote Desktop Connection, you get a message that it can’t connect? The steps below are done on the target computer (the one you want to reach), unless the step says otherwise.

The most common causes: Remote Desktop turned off on the target PC (1) or the PC not reachable on the network (2).

Step 1: check the Windows edition on the target

The target computer must run Windows 11 Pro, Enterprise or Education. Windows 11 Home doesn’t accept Remote Desktop connections — it can only connect to others. Check the edition under Settings › System › About.

Step 2: turn on Remote Desktop

  1. On the target, open Settings › System › Remote Desktop and turn on the toggle.
  2. Keep Network Level Authentication checked.
  3. Note the PC name — that’s what you type in the connection.
  4. Under Remote Desktop users, add whoever needs access (administrators already have permission).
Remote Desktop settings with the toggle on, the PC name and Remote Desktop users highlighted
On the target PC: turn on Remote Desktop (1), note the PC name (2) and check who has permission (3).

Step 3: test the network and port 3389

On the computer you’re connecting from, in PowerShell:

Command
Test-NetConnection -ComputerName RECEPCAO-PC -Port 3389

If it works by IP but not by name, the network isn’t resolving the name — the steps in how to fix error 0x80070035 (private network and network discovery) fix both problems.

Step 4: firewall

When you turn on Remote Desktop, Windows opens the firewall automatically. If another antivirus/firewall is installed, or the network is set to public, the connection may be blocked. In Windows Security › Firewall & network protection › Allow an app through firewall, make sure Remote Desktop is checked for Private networks.

Step 5: credentials

  • Use a user account from the target computer. If it signs in with a Microsoft account, enter the account’s email and password (a PIN doesn’t work over Remote Desktop).
  • On company domains, use DOMAIN\user.

FAQ

I get “Your credentials did not work”.

Check the username and password for the target computer. With a Microsoft account that only signs in with a PIN, sign in once on the target using the account password, then try again.

The screen goes black after connecting.

Update the target’s graphics driver and, in the connection, under Show Options › Display, lower the resolution.

Can I use it on Windows 11 Home?

Not as the target. Alternatives are third-party remote access tools or upgrading the edition to Pro.
