I see some strange logged report from SCOM 2012r2. When we ran the audit report and we see Privileged Logon report it shows the default administrator account domain\administrator account been used one of the sql server cluster nodes. When we checked there is no script or no where used this account. But the report logs in SCOM often where in the strange part is, when we checked the security logs for on the SQL node we couldn't see the 576. Any idea why does SCOM reports faking when there is no event logged on the SQL node. Please refer attachment.
But i found there are event logged with ID : 4634, 4672. I am confused why SCOM still shows 576 in the report instead of new event id's.
