By default, all machines in the domain will sync time from the domain controller which is the internal time server – if you have more than one DC then time will sync from the DC that holds the PDC emulator FSMO role. I don't think net time lets you view last sync though however "net time ?" gives a set option, so it's like 1/2 of what your looking for. w32tm /unregister - removes the time service from the computer. w32tm /unregister w32tm /register net start w32time. If this does not work try again but this time for the resync command add /rediscover. The PDCe is the master time keeper, and all other devices in the domain should match the PDCe. Active Directory provides a time synchronization hierarchy that ensures that time dependent protocols such as Kerberos will work correctly. – Not Kyle stop stalking me May 16 '12 at 13:26 Event source: W32Time. Most system logs include a time stamp that you can use to determine when problems occur and in what order the events take place. Unfortunately the Source remains as Local CMOS Clock. Displays all configured peers you have configured. w32tm set time source
