Windows Time And The W32TM Service

Nathan Winters, a MS infrastructure pro, has an article on the TechNet blogs site that goes into great detail on how time works and is synchronised in a Microsoft Active Directory network.  It’s a good read and goes into all sorts of detail.  I doubt you’ll have any questions after reading it.

Windows Time is critical for the correct functioning of the Kerberos protocol which is the primary authentication and authorisation method used in an Active Directory environment.  Many of these problems I’ve encountered have been a result of time not being syncronised.  Speaking of which, I’m usually surprised by how few people realise that there already is a synchronisation mechanism running in an AD environment.  So stop shopping for a third party clock synch product and read this article an you will understand how time synch in AD works, how to configure it and how to troubleshoot it.
