This section lists some NTP settings which can be used to configure / troubleshoot the Windows NTP Service.
Question #1 – How can I check what time source is being used by Windows?
Open an administrative command prompt and run “w32tm /query /source”. If you are synchronizing with a remote computer, the name from the computer should be listed. If you are using a hardware clock you should see “local CMOS Clock”
Question #2 – How can I let the computer sync its time with the the default time hierarchy?
Open an administrative command prompt and run:
w32tm /config /syncfromflags:domhier /update
net stop w32time
net start w32time
If the server is a DC you might wish to use the following instead
w32tm /config /syncfromflags:domhier /update /reliable:yes
net stop w32time
net start w32time
This command tells Microsoft Windows to go and look for the best time source in the domain hierarchy.
Question #3 – How to force the synchronization with the current configured NTP Source / timeserver?
via
w32tm /resync
Question #4 – How to show the NTP source which is currently used?
via:
w32tm /query /source
Question #5 – How can I get a list of peers which are currently used?
via:
W32tm /query /peers
