What ERROR_NOLOGON_SERVER_TRUST_ACCOUNT means

ERROR_NOLOGON_SERVER_TRUST_ACCOUNT means the credential supplied for a user-style logon is a server trust account. Windows is rejecting the account type for this access path; the result is not a generic indication that the workstation-to-domain secure channel is broken.

Diagnostic boundary

Preserve the account name, domain, logon type, target server, and the API or service that performed the logon. Confirm whether the supplied principal is a normal user/local account or an account carrying server-trust semantics. This distinction matters because changing passwords or repairing a machine trust relationship does not correct the use of the wrong account class.

  • If an application or script supplied the credential, inspect how the principal is selected and whether a computer/domain-controller account was substituted for a user account.
  • If the failure appears only on one target, compare the exact credential source and logon type before changing domain membership or trust configuration.
  • Keep any later authentication status separate; it may identify a second problem after the account-type error is corrected.

Recovery

Use the intended global user account or local user account for the access operation. Modify trust or secure-channel state only when independent evidence shows that the trust itself is unhealthy.
