673: Service Ticket Granted

On this page

This event varies depending on the OS.

Win2000

Whereas event ID 672 lets you track initial logons through the granting of TGTs, this lets you monitor the granting of service tickets. Service tickets are obtained whenever a user or computer accesses a server on the network. For example, when a user maps a drive to a file server, the resulting service ticket request generates event ID 673 on the DC.

User Name and User Domain identify the user.
Service Name corresponds the computer name of the server the user accessed.
Client Address specifies the IP address where the user resides.

Win2003

W3 uses this event ID for both successful and failed service ticket requests.
