The cause of the requested session access is denied error
The requested session access is denied error usually happens when you access a server remotely over RDP. It does not only occur to Windows Server 2012 R2 but also to Windows Server 2016/2019/2022, Windows 10/11, Azure VM, Hyper V, etc. The causes of requested session access denied are various, including appropriate Windows Group Policy, network issues, and lacking administrative privileges.
How do I fix the requested session access denied?
First of all, make sure that you are not attempting to make an administration RDP connection to the remote server. If the requested session access is denied error still exists, try more solutions.
Solution 1. Add the user to the Remote Desktop Users group
If the user that you are attempting to log in over RDP isn't added to the Remote Desktop Users group, you can get the error - the requested session access is denied in Windows 10/8/7/11 and Windows Server 2012 R2/2016/2019. At this point, you can go to Group Policy Management Editor to change the setting.
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
Step 3. Right-click on the “Restricted Groups”, and then click on “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”.
Step 7. Now the user is been added successfully.
Way 2. Use administrator account
If the error happens when you try to access a server from a Mac computer over RDP, you can see if your account is missing administrator rights. If not, just log out of the current account and then log into the administrator account. After that, you can run the Remote Desktop client app on Mac to access the server again.
