InformationThis policy setting determines whether users can log on as Remote Desktop clients. 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 prior to Windows 7, Remote Desktop Services was known as Terminal Services, so you should substitute the older term if comparing against an older OS.
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.
If you assign the Deny log on through Remote Desktop Services user right to other groups, you could limit the abilities of users who are assigned to specific administrative roles in your environment. Accounts that have this user right will be unable to connect to the computer through either Remote Desktop Services or Remote Assistance. You should confirm that delegated tasks will not be negatively impacted.
