WN25-MS-000120 - The Windows Server 2025 'Deny log on through Remote Desktop Services' user right on domain-joined member servers must be configured to prevent access from highly privileged domain accounts and all local accounts and from unauthenticated access on all systems.

Information

Inappropriately granting user rights provides system, administrative, and other high-level capabilities.

The 'Deny log on through Remote Desktop Services' user right defines the accounts that are prevented from logging on using Remote Desktop Services.

In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower-trust systems helps mitigate the risk of privilege escalation from credential theft attacks, which could lead to the compromise of an entire domain.

Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks.

The Guests group must be assigned this right to prevent unauthenticated access.

Solution

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment >> Deny log on through Remote Desktop Services to include the following:

Domain Systems Only:
- Enterprise Admins group.
- Domain Admins group.
- Local account (see Note below).

All Systems:
- Guests group.

Note: 'Local account' refers to the Windows built-in security group.
