How do I fix RDP error “The requested session access is denied”?

“Hi. I have a Windows Server 2012 R2 Terminal Server into which users can RDP. But yesterday I got the RDP error “The requested session access is denied”. I don’t know what can I do to fix the problem. Any suggestions?”

The Requested Session Access is Denied

Why RDP “the requested session access is denied” error occurs?

Meeting with RDP errors when accessing a remote PC is not strange actually. And it is said that the issue may be because one of the PCs lacks administrator privilege when using the RDP or a security option enabled preventing non-admins from connections.

3 ways to fix the RDP error “ The requested session access is denied” 

Here we sort out 3 solutions for you to get you out of the RDP error “The requested session access is denied”. Follow me to operate.

Way 1. Add user to the RDP Users Group

As we mentioned in the above text, if the host PC is non-admin, then the connection won’t be achieved. Therefore, we can add user to the Remote Desktop Users Group.

Step 1. Press Win + R and then enter “gpmc.msc”, and then press the “Enter” key.


Step 2. In the Group Policy Management Editor interface, Navigate to:

Computer Configuration\Policies\Windows Settings\Security Settings\Restricted Groups

Restricted Groups

Step 3. Right-click on the “Restricted Groups”, and then click on “Add Group...”.

Add Group

Step 4. Enter the group’s name like “0SI Admin”, and then click on “OK”.

Step 5. In the Properties interface. Locate “Members of this group”, click Add > Browse, and then add members. Click on “OK”.

Step 6. Now you can see the members of this group. Click on “OK”.

Way 2. Use Administrator Account

If the problem remains after you've tried the preceding solutions and you're still getting the RDP "The requested session access is denied error," you can see if your account is missing administrator rights. You can switch users and then log back into the administrator account if it's not an admin. Run RDP after that to see whether the problem has gone away.
