Production-minded guidance for endpoints, servers, updates, cloud services, administration, and supportable operations.
Metadata cleanup removes AD data that identifies a domain controller to the replication system. The cleanup applies when a controller cannot complete normal demotion because it is no longer reachable.

Large LDAP result sets impose significant server work, including conversion to LDAP wire formats. Windows Server manages paged-query cookies in a server-side pool that administrators can report on and monitor.

SAM client event logging records account lookups and domain enumeration that can contribute to domain-controller CPU pressure. The diagnostic events identify the processes, services, and executables generating SAM traffic.

ETW can trace LDAP communications between Windows clients and LDAP servers, including AD DS domain controllers. Microsoft documents how to start, stop, and scope the trace with trace flags.

AD replication can fail because of DNS, networking, or security problems. The troubleshooting workflow also checks intentional disconnections, hardware failures, and firewall configuration.

AD CS can issue and manage certificates using algorithms intended to resist quantum-capable attacks. The current documented AD CS post-quantum algorithm is ML-DSA, with platform and certificate-format requirements.

Certificate Enrollment Web Service accepts enrollment over HTTPS for users and computers. Together with the policy service, it supports policy-based enrollment for non-domain or temporarily disconnected domain clients.
Read the explainer
The policy web service supplies enrollment-policy information to non-domain or temporarily disconnected domain clients. It queries AD DS over LDAP or LDAPS and supports policy retrieval, enrollment, and renewal over HTTPS.

NDES acts as an AD CS registration authority for devices that lack domain credentials. It uses SCEP to support scalable certificate issuance to network devices in trusted closed networks.

The Microsoft Root Certificate Program distributes trusted and untrusted root information used by Windows trust decisions. Trusted and untrusted certificate-list functionality is designed for connected and disconnected environments.
