Hello, we have w7/w10 pc's and we are having issues with time sync. We changed our PDC to use NTP.

Now on a W7 workstation, i did a w32tm /query /source, and it came back with NTD5S, is that right ??

:\windows\system32>w32tm /query /configuration

That looks fine.

Another  useful command is W32TM /stripchart /computer:{DCname}

This will verify that the local machine is synchronised to the DC, and display any skew.
