Policy Change Event: 617

Event ID 617 – Kerberos Policy Changed

This event is logged whenever the Kerberos policy is changed. The "User Name" field of the 617 event log does not identify the actual user who changed the policy, as these policies are configured in a group policy object and applied to the computer.

This event is logged only when the modified policy is applied rather than when the group policy object is actually changed.

This log data provides the following information:

• User Name
• Domain Name
• Logon ID
• Changes Made

Why does event ID 617 need to be monitored?

This event should be monitored, as unauthorized and unplanned changes in Kerberos policy warrant further investigation.
