Windows Event Id 675 Rather look at the User Name and Supplied Realm Name fields, which identify the user who logged on and the user account's DNS suffix. This event, which is similar to Kerberos's event ID 673, not only specifies which user account logged on but also identifies the client system from which the user initiated the logon. All Kerberos events, including failed logon attempts, include Client Address.

I have a Single Site and a single DC.  Why is it using the email address on the username?  We do not host our exchange email. You can distinguish between logons that failed because of bad usernames as opposed to bad passwords. As I explained in my February 2001 article, Windows 2000 supports both Kerberos and Windows NT LAN Manager (NTLM). This provision is a tremendous advance over NT's failed-logon tracking, which only logs the username and domain name.

Be sure you understand event ID 672's relationship to event ID 673. I showed you what Windows logs when a user enters a bad password but what about all the other reasons a logon can fail such as an expired password or disabled If the username and password are correct and the user account passes status and restriction checks, the DC grants the TGT and logs event ID 672 (authentication ticket granted). To capture these events, open the Microsoft Management Console (MMC) Domain Controller Security Policy snap-in from the DC.

The User field for this event (and all other events in the Audit account logon event category) doesn't help you determine who the user was; the field always reads SYSTEM. The User field for this event (and all other events in the Audit account logon event category) doesn't help you determine who the user was; the field always reads SYSTEM. Pre-authentication types, ticket options, encryption types and result codes are defined in RFC 4120. If the ticket request fails Windows will either log this event, 4768 or 4771 with failure as the type.

The only relevant information not present in the other audit events is the Kerberos result code that indicates the reason why the authentication was not granted.

Client Address identifies the IP address of the workstation from which the user logged on. When a user employs a domain account to log on at a workstation, the workstation contacts the DC to verify that the user is authentic and to determine account status and This event records that a Kerberos TGT was granted, actual access will not occur until a service ticket is granted, which is audited by Event 673.
