I joined some computers to Windows domain, but the clock was so wrong (one day ahead).... Here is a simple how to set time on ad domain controller, but this also works with Windows servers overall.
w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /manualpeerlist:ntp ip address-or-dns /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time
then check the results
w32tm /query /source
w32tm /query /configuration
