About this tag
The enforcemode tag on WindowsForum.com covers discussions about Microsoft's Kerberos CVE-2025-26647 protections, specifically the transition from audit to enforcement mode for certificate-based authentication on domain controllers. Content highlights the AllowNtAuthPolicyBypass setting introduced in April 2025, which allowed administrators to test stricter authentication policies before enforcing them.

The tag focuses on troubleshooting, rollout strategies, and operational challenges related to enforcing Kerberos security updates in enterprise Active Directory environments.
