Information
This policy setting determines whether users can log on as Remote Desktop clients. After the baseline Member Server is joined to a domain environment, there is no need to use local accounts to access the server from the network. Domain accounts can access the server for administration and end-user processing. This user right supersedes the Allow log on through Remote Desktop Services user right if an account is subject to both policies.
The recommended state for this setting is to include: 'Guests'.
Note: In all versions of Windows Server prior to Server 2008 R2, Remote Desktop Services was known as Terminal Services, so you should substitute the older term if comparing against an older OS.
Rationale:
Any account with the right to log on through Remote Desktop Services could be used to log on to the remote console of the computer. If this user right is not restricted to legitimate users who need to log on to the console of the computer, unauthorized users might download and run malicious software that elevates their privileges.
Solution
To establish the recommended configuration via GP, set the following UI path to include 'Guests':
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Deny log on through Remote Desktop Services
Impact:
Accounts in the Guests group will not be able to log on to the computer using Remote Desktop Services.
