Monitor Knowledgebase


An error occurred during an attempt to read the data that is stored in the AD FS configuration database during a regularly scheduled trust monitoring interval. This error will abort trust monitoring until the next trust monitoring cycle begins.

The default setting for the AD FS trust monitoring time interval is 1 day. This monitor will generate a Yellow state if Event ID 164 occurs at least four times within 5 days. If the same problem does not occur again within 1.5 days, the health state of this monitor will change back to a Green state and the alert that is generated by this monitor will be resolved automatically.


The following are possible causes for this event:

  • The AD FS configuration database is not reachable.

  • The database service was interrupted or taken offline while the Federation Service was accessing the AD FS configuration database.


Verify that the AD FS configuration database is reachable and that the identity of the AD FS service user account has the necessary permissions to write to the database. For more information, see "Verify that the Federation Service can connect to the AD FS configuration database" section in the AD FS troubleshooting guide.

Retry read access to the AD FS configuration database after you investigate the status of the database service. To set the trust monitoring interval, use the MonitoringInterval parameter on the Set-ADFSProperties cmdlet while using Windows PowerShell for AD FS.
