  3. At the command prompt, type W32TM /query /status, and then press ENTER.
    This command displays the status of the Windows Time service synchronization. The Last Successful Sync Time line of the output displays the date and time that you ran the W32TM /resync command in the previous step. Also, check the computer name that is shown as the Source. This should be the name of a domain controller (or an administrator-configured time server) in the same Active Directory domain as the local computer.
To verify that the Windows Time service synchronized successfully with its time source, confirm that Event IDs 35 and 37 appear in Event Viewer. If there was a recovery from a previous failure to synchronize with the time source, you also see Event ID 138, which indicates that the Windows Time service is synchronized correctly.
