Keberos Key Distribution Center
It provides two services (TCPIP Port 88):
  • Authentication Service: Issues Ticket-Granting Tickets (TGTs) to allow connection to the "Ticket-Granting Service" in a trusted domain.
  • Ticket-Granting Service (TGS): Issues tickets for making connections to computers in the local domain for clients having a TGT.
 
License Logging Service
Is used to provide license tracking on a server or Domain Controller (DC).

It will post a warning in the Application Event Log with Event ID 221, if there are more users accessing the machine than there are licenses.

The licenses can be configured on the server by opening the Control Panel and double clicking the Licensing-applet.

Note if running an Exchange Server this service will conflict with the SBS License control, and will block out users eventhough enough Exchange Server Licenses. Disable this service to avoid the conflict or install the patch MS KB Q305138.

Logical Disk Manager Watchdog Service that detects the appearance/disappearance of hard drives and the partitions they contains.
 
Logical Disk Manager Administrative Service
