The remote desktop in licensing protocol error is one that occasionally pops up for some users who utilize the Remote Desktop Connection tool in Windows 10.

The full error message states:

The remote computer disconnected the session because of an error in the licensing protocol. Please try connecting to the remote computer again or contact your server administrator. 

Consequently, users can’t connect with Remote Desktop Connection. These are a few fixes for that RDC error.

  2. Run Remote Desktop in the built-in admin Account
  3. Delete the MSLicensing Registry Key
  4. Scan the Registry

  3. Now your Remove Desktop Connection should open with administrator rights.

Some users have confirmed they’ve fixed the remote desktop mslicensing issue by running Remote Desktop Connection as an administrator.

Running RDC as administrator ensures that the app has the required permissions to modify the registry.

2. Run Remote Desktop in the built-in admin account

  2. Right-click on the Command Prompt and select Run as administrator.
  3. Type in the following command and press Enter: net user administrator /active:yes

Alternatively, try running RDC within an admin account. You can activate a built-in admin account with the Command Prompt.

  10. Restart your desktop or laptop, and run Remote Desktop Connection as an administrator.

Users have also confirmed that deleting the MSLicensing key in the registry fixes the RDC licensing protocol error.

4. Scan the Registry
