Time Synchronization with AD

I had weird issue with Active Directory service where there were no Windows Time service at all. w32time.dll and w32tm.exe files were in place. So I just registered w32time.dll by:

w32tm /register

After that Windows Time service appeared under ‘services’. Start service by:

net start w32time

Then to check that time service work on DC run from any client:

w32tm /stripchart /computer:dc_ip /samples:5 /dataonly

To synchronize with DC right away on client run:

w32tm /resync

In case client synchronizes with outside NTP instead of DC edit HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ W32Time\ Parameters. If it has ‘NTP’ in ‘Type’ parameter then change it to ‘NT5DS’ and run:

w32tm /config /update
