RDP Connection Error: No Remote Desktop Client Access Licenses Available

So, as of recent I have had several occurrences of this wonderful RDP error as of late, so I figured I'd share what I've found to be helpful. It pops up upon connection and goes like this: "Remote session was disconnected because there are no Remote Desktop client access licenses available for this computer. Please contact the server administrator." And it looks something like this:

Oddly enough this type of error has noting to do with licensing, it's typically the cause of a bad Registry Key. But before we go Registry diving, I suggest attempting to rebuild the default RDP profile. This may work in some cases, but more than likely, you will be following the later steps. To remove the "Default.rdp" file:

1. Open File Explorer
2. Navigate to Documents
3. Locate "Default.rdp" and Delete it

Attempt to launch an RDP session. If that fixes your error than you'r done. If not, follow these next steps to remove the Registry Key that's causing the issue.

1. Click the Start button and in the search bar type Regedit.exe
2. Navigate to the following registry key:
1. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing
3. Delete the key
4. Attempt to reconnect to the remote PC

If it doesn't work than you will get the following error message: “The remote computer disconnected the session because of an error in the licensing protocol“;

Then all you need to do is Right-Click on the Remote Desktop Connection icon and select "Run as Administrator".
