About this tag
The ntlm retirement tag covers Microsoft's ongoing efforts to phase out NTLM authentication in Windows. Recent discussions focus on new Kerberos capabilities in Windows 11 and Server Insider builds, including IAKerb and LocalKDC, which aim to eliminate scenarios that historically required NTLM fallback, such as blocked domain-controller access and local-account connections. This represents a strategic push to make NTLM retirement operationally feasible by removing architectural dependencies that kept the legacy protocol in use. The tag addresses enterprise IT and security concerns around authentication modernization, protocol deprecation, and the practical steps Microsoft is taking to reduce reliance on NTLM.
