Well, there's a lot of "it depends" here. Like, is it a Domain Controller?
Do you have a Domain Controller? It the server a member of a Domain
(whether or not it itself is a DC)?
Anyway... the default mode is for all domain members (servers and
workstations) to sync to the Domain controller. For this you need to do
nothing. It is built in.
In any case, you can always do the following...
From the command line, go to the machine you want to configure to auto-sync,
and type in the following....
net time /setsntp:time.nist.gov
This particular setting will cause that machine to sync to time.nist.gov (a
public time server).
If you want it to sync to another internal machine, type the internal
machine's name instead.
Do this to each and every machine. Once set, this setting with hold through
reboots.
Having said all that, the "norm" is to configure your Domain Controller to
sync to the public time server using the above technique, and then let all
the other Domain members (including webservers) to auto-sync to the DC (for
that you need do nothing, it's default).
It will work either way.
