Domain Time Client
Version 5.2

Please read the Installation Topics pages before installing.

In most cases, you'll want to use Domain Time Manager to install and configure Domain Time Servers and Clients remotely across your network from your management workstation. If that's what you'd like to do, you can skip these installation instructions and read the Network Rollout documentation instead.

It's also possible to use an existing installation of Server install to another machine remotely using the command-line. This option is for advanced users. See the Command-line Options page for details.

If you use cloned OS images to install machines, please read this article from our knowledgebase about configuring Domain Time properly on your clone image.

  • Windows Nano Server has special installation requirements. See the Nano Server FAQ for details.

  • If you will be installing Domain Time Client on a virtual machine, see this article from our knowledgebase for more information on proper use with virtualization systems.

  • If you are installing Domain Time Client onto a Windows Cluster, there are considerations regarding Cluster Service startup dependency on the Windows Time Service. Please see the NoSync section of the Advanced -> Windows Time Mode settings for more information.

  • Check your routers and firewalls to be sure the ports for the time protocols you'll be using are open. Port 9909 TCP & UDP should always be open bi-directionally between Domain Time Servers and Clients. Port 123 UDP should be allowed if you will be using the NTP protocol for time synchronization. Ports 319 UDP & 320 UDP should be open bi-directionally for PTP use.

    Domain Time version 5.2 and later includes a handy utility for adding the correct ports to the internal Windows firewall. Issue the following command from a command-prompt elevated with admnistrator privileges:

      dtcheck /firewall:open

  • If you will be installing Domain Time onto machines with AMD processors, we highly recommend you update your processor drivers (a.k.a. PowerNow!) to the current version for your operating system available from AMD's website to avoid known hardware timing issues. Please see this article from our knowledgebase for more info: KB2007.817.


  • To install or upgrade Domain Time Client directly to a single machine from the distribution setup files:

    1. Run the Setup program from the CD to install the program. (If you have an older version of Client installed, Setup will give you an upgrade option. Your original configuration settings will be preserved during the upgrade). See this page for details on using the Setup utility.

    2. Start the Domain Time Client applet from the icon in the Windows Control Panel to configure it.
      Note: On systems with User Account Control (UAC) enabled, you may need to Shift+Right Click and choose Run As... from the context menu to launch the Control Panel applet. On Windows Server Core, type in domtimec.cpl on the command line)

      1. Use the Obtain the Time property page to set Client to get the time:

        • from local GPS Network Time Servers, Domain Time Servers, or from other reliable network time sources, or

        • by auto-discovering a server (as configured by the Discovery Options on the Obtain the Time property page).

        • Using Active Directory policies.

      2. Test your installation

        • Click the Sync button on the Control Panel Applet.

        • Click View Log button to see the service activity log. You should see messages indicating that the Domain Time service set its time correctly from the time source(s) you selected.


  • Use Domain Time Manager to remove the program remotely.

  • Or, use the Programs and Features (Add/Remove Programs) utility from the Windows Control Panel to remove the program.

  • You may also use the original Setup program to remove the program. Run Setup and choose the Remove option.

  • The program can also be uninstalled from the command-line. See the Command-line Options page for details.
