COMADMIN_E_NOUSER

COMADMIN_E_NOUSER is the failure HRESULT 0x8011040F (signed decimal -2146368497, unsigned decimal 2148598799). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x040F.

COM+ identity, role, and administration security: exact meaning of COMADMIN_E_NOUSER

At least one user supplied to a COM+ administration operation cannot be resolved as a valid account. User or role membership processing validates security principals against the target machine or domain.

AllStat records this condition as “One or more users are not valid”.

Evidence to collect before repair

The COMADMIN_E_NOUSER investigation needs the original account string and target computer so the exact failing boundary remains reconstructable.
For COMADMIN_E_NOUSER, preserve SID lookup result and domain/trust status; it anchors the failure to the real administration object.
Evidence for COMADMIN_E_NOUSER should include whether the account is local, domain, managed service, or built-in, captured before a repair changes state.
Collect the role or application identity property receiving the user when diagnosing COMADMIN_E_NOUSER; without it the symbolic HRESULT is underdetermined.

Where COMADMIN_E_NOUSER occurs

This result concerns a concrete COM+ identity, role, credential, or call-authentication contract; successful interactive access does not prove that the COMAdmin or application identity can perform the operation. In the specific case of COMADMIN_E_NOUSER, log the original account string, resolved SID if any, domain reachability, trust context, and whether the account was renamed or deleted.

Diagnostic sequence for COMADMIN_E_NOUSER

To isolate COMADMIN_E_NOUSER, resolve the account under the target server security context.
For COMADMIN_E_NOUSER, verify that the SID still identifies the intended principal.
At the COMADMIN_E_NOUSER boundary, replace source-machine local accounts with target-appropriate identities.
The next COMADMIN_E_NOUSER diagnostic action is to apply only the failed role or identity change.
To isolate COMADMIN_E_NOUSER, repopulate the affected collection and confirm the stored SID-backed user.

Retry and recovery

Use a resolvable SID-backed principal and rerun only the failed membership change.

Practical administration scenario

A role-membership script references an account removed from Active Directory, and COM+ cannot add it.

Difference from nearby COMADMIN results

COMADMIN_E_INVALIDUSERIDS is tied to user entries carried in an application file, whereas this result can arise during direct administration.
