Configure Windows Time on Win Server 2003 Root Domain Controller

Hi All

I have reviewed all the documentation that I have located on the Windows
Time Service in Windows Server 2003. However, I still feel somewhat shaky
about this topic, so I would appreciate your help to make sure that I have
configured both the server and the clients correctly.

GENERAL INFORMATION
1) We have a small client/server network. The Root Domain Controller has THE
WinDOWS Server 2003 SP1 Op Sys, & there are 5 clients using either Win XP Pro
SP2 or Win2000 Pro. Just to confirm, there is only 1 DC in this network.

2) The Root Domain Controller is the network's reliable time server so the
following entries are in its registry:

-HKEY_LOCAL-MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config has
AnnounceFlags set to (5).

-In W32Time\Parameters Type is set to NTP.

-In W32Time\TimeProviders\NtpServer has Enabled set to (1)

3) In W32Time\Parameters,the entry in NtpServer is:

0.north-america.pool.ntp.org,0x1 1.north-america.pool.ntp.org,0x1
2.north-america.pool.ntp.org,0x1 time-a.nist.gov,0x1


QUESTIONS:
(a) In point 3) above, how is the manualpeerlist entry used?

-Does Windows Time Service try to connect to the first entry in the list,
0.north-america.pool.ntp.org,0x1, and then if that fails does it then try the
second location in the list?

-Or does it contact each address in the list, and then average the times
before synching the DC's time?

-Or does it rotate sequentially through each address in the list as each
new time check is made?

(b) In W32time\Paramters, I appended the 0x1 switch to the end of each
address entry. Please note that I did not place a space between the end of
the address name (time-a.nist.gov,0x1) and the comma before the 0x1 switch.
Is the lack of a space correct?

(c) In W32Time\Parameters, I think that appending the 0x1 switch to an
address means that Windows Time Service in the Root Domain Controller will
connect to the internet-based time server(s) every ??-seconds where
(??-seconds) is the number entered in the W32Time\TimeProviders\NtpClient
entry for SpecialPollInterval. I have 3600 entered here, so I believe that
means that the RDC tries to contact 0.north-america.pool.ntp.org0x1 every 1
hour. Is this correct? If it is not, then how does one control how frequently
the RDC contacts the time server(s)?

(d) All of the client computers were joined to the network and then were set
to their default w32time settings using the following procedure from the
command line:

-w32tm /unregister <Enter Key>
-w32tm /register <Enter Key>
-net start w32time <Enter Key>
-w32tm /resync <Enter Key>

Will this procedure set the clients to automatically use the RDC as their
time source? Please advise Which setting controls how frequently that they
will automatically connect to the RDC to synchronize their time?

Thanks for your help!!

RE: Configure Windows Time on Win Server 2003 Root Domain Controller

Have you been able to resolve your questions? Can you post and answer your
topic if so? I am curious about this exact topic, and if your configuration
is working, i would like to apply it too, to my Root DC.

RE: Configure Windows Time on Win Server 2003 Root Domain Controll

Hi Tim

I haven't received any response to this question so I don't know for sure
the answers to my original questions. That said, it does appear that this
configuration is, at the least, okay. I am NOT receiving any error messages
except when one of the NTP servers, for example:
2.north-america.pool.ntp.org, can not be reached. When this happens, I
usually see that a connection is made on the second or third attempt.

At this point, I feel confident enough to say that you can give my
configuration a try, and I don't think that you will hurt yourself with it if
your system topology is the same as or very similar to ours.

RE: Configure Windows Time on Win Server 2003 Root Domain Controller

Hello Tim,

If you have one or more dc's just follow this document:

Even better is a new posting with your situation and event viewer errors.
