Hi,

We have an isolated IP WAN not connected to the internet, and each site does
connect via IP but is not part of the same domain.

There is a cluster at each location so there is DNS and Active Directory on
each cluster. I think because of the Active Directory we no long have the
"Internet Time" tab on the Date/Time control panel. Does anyone know if that
is true? How can I get the Internet Time back?

We want to set up a server at the main office as an NTP server, and each
remote location sync back to it so all sites and server are at the same time.

Any thoughts on why the Internet Time tab is gone, if it is not because
active directory is installed, and no matter how can we get it back, or how
can we use the MicroSoft NTP to sync if we don't have that tab.

Thanks. Steve.

Hi Steve,

You lose this tab once you join your computer to domain. Any domain client
will by default synchronize its time with domain controller holding PDC
master role. Make sure that your PDC master can synchronize with reliable
external time source. By default it will use UDP 123 port to access external
time source -- make sure that your firewall will this kind of traffic.

Domain logon in Windows 2000 or newer environment relies on Kerberos
protocol. This protocol relies on accurate time. If the time between the
client and DC is off by plus/minus 5 minutes (by default -- set by group
policy) logon to domain will fail.

Instead of tab you can use command line tools that come with Windows

net time and/or
w32tm
