STATUS_NO_TRUST_SAM_ACCOUNT

STATUS_NO_TRUST_SAM_ACCOUNT is NTSTATUS 0xC000018B. Microsoft defines it for a workstation trust relationship when the applicable server's SAM database does not contain a computer account for that workstation. The failure is about the machine identity used for domain trust, not the interactive user's password.

Verify the computer account before repairing the secure channel

Check whether the computer object exists in the intended Active Directory domain, whether the workstation is joined to that same domain, and which domain controller returned the status. A deleted computer object, an incorrectly recreated account, or a machine contacting the wrong domain can leave the server unable to locate the account that anchors the workstation trust.

This code is more specific than STATUS_TRUSTED_RELATIONSHIP_FAILURE. The latter reports that the workstation-to-domain trust failed; STATUS_NO_TRUST_SAM_ACCOUNT explicitly says the computer account is absent from the server-side account database used for the trust. Confirm account existence and replication visibility before resetting a machine password. If the object is present on one domain controller but absent on another, repair directory replication or account consistency rather than repeatedly disjoining and rejoining the client.
