    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.

    Hello Tim,

    If you have one or more dc's just follow this document:
    http://support.microsoft.com/kb/816042

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

    Best regards
