617: Kerberos Policy Changed

On this page

W2k logs this event each time the DC applies group policy. W3 corrects this problem and only logs the event when it detects an actual change to the policy. Kerberos policy is defined in GPOs linked to the root of the domain under Computer Configuration\Windows Settings\Security Settings\Account Policy\Kerberos Policy.

Unfortunately the Change By fields don't identify who actually changed the policy because audit policy isn't directly configured by administrators. Instead it is edited in a group policy object which then gets applied to the computer. Therefore this event always shows the local computer as the one who changed the policy since the computer is the security principal under which gpupdate runs. The time is when the policy was applied rather than the time the group policy object was changed.
