Service Account for AAD Connect Changed after reboot

My customer rebooted his server and the Sync Service won't start, we discovered that service account is showing as Local Admin instead of the expected AAD_mmmmm. Has anyone seen this before, now why ...
Azure Active Directory (AAD)

Thanks, after troubleshooting for a few hours without being able to figure out what happened we decided to uninstall and reinstall and that fixed the problem.

Hello Dean,

 

Your course of action would have been my recommendation. The AAD_xxxxx account is a local account created by the AAD Connect Wizard. The password is complex and never known. Very strange that it was changed. I usually recommend my customers to create a service account to avoid these scenarios. Then, use the Custom install method and supply your new domain service account. You can also use it to read and/or write to your AD.

    I had a very similar scenario after an update of AD Connect was installed.
