During Domain Controller (DC) patching or maintenance cycles, the Change Auditor Coordinator may generate SQL authentication errors similar to:
Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication.
SSPI handshake failed with error code 0x80090311, state 14 – No authority could be contacted for authentication.
These errors may trigger alerts, cause temporary data processing interruptions, or create concern regarding SQL connectivity or domain trust issues.
This behavior is a predictable and known condition, not an isolated issue.
It occurs due to a combination of:
During rolling DC patching:
This results in SSPI failures when attempting to authenticate using Integrated Windows Authentication.
Recent Windows updates introduced:
These changes reduce tolerance to even short authentication interruptions.
Version 7.6.2 introduced improvements including:
While beneficial, this results in:
This is by design behavior under the described conditions and does not indicate a persistent fault.
No product fix is required.
To avoid unnecessary alerts and interruptions, implement the following procedure during DC maintenance:
If no action is taken:
