Is this server a domain controller or a standalone server (not part of a
If the server is a domain controller, it is automatically the time server
for the clients that used it to logon to the domain with. All DCs in a
domain will look at the DC that holds the PDC Emulator role for time sync.
If there are child domains, the child PDC Emulator will look to the parent
domain's PDC Emulator for time sync. The is called the time service
hierarchy in aa AD domain. The top of the hierarch is the PDC Emulator at
the forest root, which should be configured to get time sync wtih a reliable
internet time source.
BUT, there is really nothing to configure with all the DCs and client
machines, other than configuring time source on the forest root's PDC
Emulator. It just works by DEFAULT, meaning out of the box.
Read my blog on how time works in an AD domain with Window 2000, 2003 and
Configuring the Windows Time Service for Windows Server http://msmvps.com/blogs/acefekay/arc...ws-server.aspx
Now if you have a simple stand alone server (not part of a domain), the
service works a litle differently. You would still set it up to sync with a
reliable external source. Then set the other standalone machines (NOT part
of a domain) as the time server so they can sync with this standalone
You can also opt to install a third party time server service for your
standalone server (non-domain member or domain controller), too. There are
many out there, some are free.
