OK, I understand. So looks like I have it setup correctly now. When i ran
the command mentioned in the article you mentioned below, there appears to
be a 00:04 to 00:06 lag between my desktop and the PDC emulator.

I find the article you reference is (KB 816042), unnecessarily complicated
(not wrong, just more complicated than necesary). Try instead
http://technet.microsoft.com/en-us/library/cc786897.aspx.
The member computers should be automatically set up to sync time correctly
when they are joined to the domain and normally they should be within a
few seconds of the time on the DC configured as the root of the time
hierarchy.
With Vista or 2008, you can check the settings on the members computers
easily:
w32tm /query /configuration
Windows XP and 2003 w32tm command doesn't have the query option, but you
can use this command:
w32tm /dumpreg /subkey:Parameters, to some of the same information.
Among other things, the should tell you that the "Type:" is NT5DS, meaning
that the computer is configured to use the domain time synchronization
hierarchy.
The corresponding registry entry is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
which should be "NT5DS".
The article at
http://blogs.msdn.com/w32time/archive/2007/09/04/keeping-the-domain-on-time.aspx
explains how time synchronization in a domain works.
Depending on the number of domain controllers, domains and sites, it may
take some time for all the domain controllers to re-synch with the root of
the time hierachy (the PDC Emulator) if it's time is changed.
If I understand correctly, the Windows time service automatically adjusts
how often it does a time sync with the time source depending on how much
time difference it finds when the synchronization happens.

It's perfectly useless to know the right answer to the wrong question.

OK, so I followed the instructions at
http://support.microsoft.com/kb/816042 to enable my PDC Emulator to sync
with pool.ntp.org. I synced it up and the date/time on it is correct.
I then went to my workstation and issued a "w32tm /resync /rediscover"
command and nothing happened. It is still a minute or so behind the
domain controller.
TIA!

Can the DC be setup to sync its time with an external time server?

Hi
-By default in domain environment all workstations sync their time with
their local site DC. All DCs sync their time with the PDCe for their
domain. All PDCes sync their time with the PDCe at the Root Domain.
-To answer your question; assuming that the DCs are in the same site as
the DCs, they should be able to sync their time with the DCs in that
site. You only need to mess with ISA server if internal connections
(between workstations and DCs) are locked.

I hope that the information above helps you.
Have a Nice day.
