My OEM is stop working and I noticed that the Oracle Management Server is not running. I am on 817 on NT. I start the service and it's not working for some reason and I start the services by issuing the command:

OEMCTRL START OMS and I got the error:

C:\>oemctrl start oms

The OracleOraHome817ManagementServer service could not be started.

The service did not report an error.
