Service Log on Error 1069 for Managed Service Account: Service Does not Start Automatically After Server Reboot

We were facing an issue with one of our applications which was using a Microsoft Managed Service Account to run two of its services. The issue was that each time the servers were rebooted (usually after monthly patching) those services could not be started, and we get a ticket from users. Also, while trying to restart the services manually, it won’t start.

So, the temp resolution was to set those services to use localsystem instead first and then configure again to use the desired managed service account.

sc.exe config “ServiceName” obj=”localsystem”

We checked on local group policy that log on as a Service was enabled for the said managed account. After some research we wanted to make sure that this also has been configured on our Domain Controller as Default Server Policy. We checked and found that this particular account was missing from the list of accounts that have been given the permission to logon as a service.
