I'm getting bombarded with the below same System Event ID:
Log Name: System
Date: 26/09/2016 9:53:23 PM
Event ID: 3
Task Category: None
A Kerberos error message was received:
on logon session
Server Time: 11:44:25.0000 9/25/2016 Z
Error Code: 0x29 KRB_AP_ERR_MODIFIED
Server Realm: MyDomain.com
Server Name: WS-WIN72230S$
Error Data is in record data.
This is from the System Event log in the past 2 days.
What does that means ?
The server getting bombarded is just the normal IT management server not domain controllers.
