About this tag
The local KDC (Key Distribution Center) is a core component of Kerberos authentication in Windows domains, responsible for issuing ticket-granting tickets (TGTs) and service tickets. Discussions on this tag focus on configuring and troubleshooting the local KDC, especially during migrations from NTLM to Kerberos-first authentication. Topics include ensuring the local KDC is properly registered in DNS, handling time synchronization between clients and the KDC, and resolving common errors like KDC_ERR_PREAUTH_FAILED. Enterprise IT administrators often seek guidance on deploying read-only domain controllers (RODCs) with local KDC functionality for branch offices, as well as securing the KDC against attacks such as Kerberoasting. The tag also covers scenarios where the local KDC is used in isolated or high-security environments.
