Domain Time II Server
Version 5.2

Domain Time II Server is a Windows system service that can be configured to obtain time from various time sources (such as GPS clocks and Internet time servers) and match the system clock to it with extreme accuracy and precision. Server then provides the correct time reliably and securely to other systems on the network.

Configuring the Server

Once installed, the Domain Time II Server service will start automatically when the system boots. All settings used by the service are read from the Windows registry.

    There are several ways to configure the Server's settings:
    1. Use the Domain Time II Server Control Panel applet on the Server machine itself.
    2. Remotely from another machine:
    3. Import settings from a saved configuration file.
    4. Use Active Directory policies.

    The following instructions describe the settings found on the Domain Time II Server Control Panel applet. Follow the links above for instructions on the other configuration methods. The applet can be configured whether the Domain Time II Server service is running or not.

    Launch the applet
    There are several ways to launch the Domain Time applet:

    • From the System Tray (Notification Area) Icon: Double-click the Domain Time icon to launch the Domain Time II Server applet. You may also right-click the tray icon to launch the applet, as well as many other installed Domain Time II components and utilities from the context menu.

    • From the Windows Control Panel: Click the Domain Time Server icon (it may be located in the Clock, Language, and Region section).

      Note: On systems with User Account Control (UAC) enabled, you may need to Shift+Right Click the icon and choose Run As... or Run As Administrator from the context menu to launch the Control Panel applet.

    • From the the command-prompt: Launch the applet by typing domtimes.cpl in the Windows Start --> Run dialog or at a command prompt (the file itself is located in the \System32 folder).

The Control Panel Applet

The Domain Time applet has two panels. On the left is the navigation tree, which lets you pick a configuration property page to view by left-clicking an item in the tree. Right-clicking in the navigation tree will bring up a context menu with shortcuts to various functions, such as Connect to another computer..., the text and drift logs, online help, etc. On the right-hand side of the applet is the currently-selected configuration page.

    Click the Domain Time Server (local) item on the navigation tree to display information about the installed service, including version information, Serial Number, stats, and Start/Stop control.

    The Status and Statistics display gives you a quick overview of the state of the Domain Time service. This section will be blank if the service is not started, and may take a few moments to display after a service restart. Click the Refresh button to update the display.

    Use the Service Control section to stop and restart the Domain Time service. Most changes you make using the Control Panel applet are dynamic and should not require you to restart the service.

    Connect to another machine running Domain Time

    You can also use the Domain Time Control Panel applet to connect to and configure other machines running Domain Time version 5.1 or later. This is particularly useful for quick configuration changes to a few machines, or for configuring Domain Time on Windows Server Core systems. If you need to configure many machines, you will want to use Domain Time Manager and/or use Active Directory policies instead.

    You must be able to log on to the remote machine with an account that has administrative rights to the remote system. Your machine must also have sufficient network connectivity to authenticate with the remote system using Microsoft networking (see the Planning page for complete network information).

      Right-click any item on the navigation tree and select Connect to another computer... from the context menu. If necessary, you'll be prompted to enter an administrative account and password to the remote machine.

        Connect to...

      When connected, the Domain Time Server (local) item in the navigation tree will change to display the name of the remote computer (you'll also see the name in the title bar and the background color of the menu tree will change). Now, any changes you make to the applet will be made directly on the remote system. All of the functions of the Control Panel applet, such as the log viewers, stats display, etc. also behave as if you were directly using the applet on the remote machine.

      Remote Control...

      To disconnect from the remote system, you can either right-click -> Connect to another computer... again and choose Local computer, or simply close the applet.
