STATUS_DS_VERSION_CHECK_FAILURE
The server version is incompatible with the directory behavior level
Active Directory behavior versions control which DC versions and directory features are supported. This status means the Windows build or DC role path is incompatible with the current forest, domain or DC behavior version.
It usually appears during promotion, startup or compatibility checks. The useful evidence is the behavior level and server version, not the user object or LDAP attribute being accessed.
What to inspect
- Record the forest functional level, domain functional level and server OS build.
- Check whether the DC is being promoted into a domain that has dropped support for that version.
- Review upgrade, demotion and rollback paths before changing behavior levels.
