Time Server

[Steven Platt]

I have a 2000 domain with XP workstations. I cannot locate Windows Time
Service under Computer Configuration\Administrative Templates\System\ I
think I have to update it somehow. I couldn't find any documentation to do
so. Anyone know how this is done?

NET TIME synchronizes the computer's clock with that of another computer
or domain, or displays the time for a computer or domain. When used without
options on a Windows Server domain, it displays the current
date and time at the computer designated as the time server for the domain.
This command allows setting the NTP timeserver for computername.

\\computername Is the name of the computer you want to check or
synchronize with.

/DOMAIN[:domainname] Specifies to synchronize the time from the Primary
Domain
Controller of domainname.

/RTSDOMAIN[:domainname] Specifies to synchronize with a Reliable Time
Server
from domainname.

/SET Synchronizes the computer's time with the time
on the specified computer or domain.
/QUERYSNTP Displays the currently configured NTP server for this
computer
/SETSNTP[:ntp server list]
Sets the NTP time servers to be used by this computer. This
may be a list of IP addresses or DNS names separated by
spaces.
If multiple timeservers are listed, the list must be
surrounded
by quotes.

Thanks, Charlie, but I found what I was looking for. I just added a GPO to
the OU in question and it appeared. I wanted to setup a common timeserver
for all my workstations via a GPO not from the command line. Thanks for you
help, though.

By default, all Windows XP, 2000 and 2003 Server computers that are
"members" of a Windows 2000 (or 2003) Domain will automatically synchronize
time with the Domain Controllers when they start and periodically
thereafter; you don't have to install or configure anything (unlike with
Windows NT 4).

Windows XP and Windows 2000 use the Internet standard Network Time Protocol
(NTP) or Simple NTP, not the old Windows NT 4 Time Service, which did NOT
use NTP. Unless you disable it, all Windows 2000 and 2003 servers run the
NTP service (daemon) and will respond appropriately to time synch requests
(NTP client requests) form other computers.

To get all of the domain computers to have accurate time, make sure you
configure the Domain Controller (or, if there are multiple Domain
Controllers, the one with the PDC Emulator role) to sync time from a
reliable external source.

See
http://www.microsoft.com/technet/pr...Kit/ef81ebc8-4803-42d7-b72a-be7e9f16d183.mspx
and
http://www.microsoft.com/technet/pr...ons/8990703a-a197-4717-b6e5-b7406d9f91f0.mspx.
For example, to specify an external time source (e.g. on the Domain
Controller at the root of your time sync hierarchy):

w32tm /config /syncfromflags:manual /maualpeerlist:time-a.nist.com
w32tm /config /update

For an explation of the various optons availble use the command:\

w32tm /?

You don't need to and, except in quite exceptional circumstance shouldn't,
configure the time service on domain member computers.

See http://www.eecis.udel.edu/~mills/ntp/index.html for some "reliable"
time sources.

Hi Bruce,

Is there a way to Prevent the DC time service from trying to sync to
an external source? I set the w32time parameter to "NoSync" but it
still tries to sync externally?

My network depends very heavily on the time on the computers and the
servers. Unfortunately the "Required time" has to be about 5 minutes
behind the "regular time". This is so it is in sync with the
building’s clocks which are 5 minutes off for some weird reason.

I have a DC that is the time server and also use net time as well as a
batch file just to make sure. However, the DC keeps changing time
after trying to sync to an external time server.

Thanks
