We are running in Hybrid mode using Azure AD Connect ver 126.96.36.199 Running on a Windows 2019 Server Version 1809
The service is running fine until I reboot and then my System event log fills up with 100's of messages over the course of 15 - 30 seconds with the following events:
Description: The Microsoft Azure AD Sync service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 0 milliseconds: Restart the service.
Description: The Microsoft Azure AD Sync service failed to start due to the following error:
The service did not start due to a logon failure.
Description: The ADSync service was unable to log on as SCIINC\AAD_0315e1ea987c with the currently configured password due to the following error:
The user name or password is incorrect.
I know the username and password work because when i restart the service it stops and restarts with no issues.
I have changed the services to Automatic (Delayed Start) - Same issue.
I have removed and reinstalled Azure AD Connect and still have the same issue.
We monitor these services because I want to know if there is an issue so I get 100s of messages each time the server is rebooted.
Any assistance would be greatly appreciated.
