    Version 5.2 Basic Requirements
    These are the system requirements for the current version of Domain Time II (except where noted). System requirements for older versions are here.

    • Windows XP, 2003 (&R2), Vista, 2008 (&R2), Win7, Win8.x, 2012 (&R2), Win10, 2016
      32-bit (x86) and 64-bit (x64) versions available. ARM is not supported. TCP/IP Port Usage

      Specific Application Notes:
        .  Domain Time II Server

        • DTTray System Tray applet not accessible when running on Windows Server Core.
        • Using Domain Time II Server to serve time while running on a virtual machine is not supported. 1
        • Nano Server may require MS SNMP trap support (wsnmp32.dll) be manually copied to the /system32 folder before Domain Time installation.

        .  Domain Time II Client (includes DT-Set command-line client)

        • Domain Time II Client may be used on virtual machines.
        • DTTray System Tray applet not accessible when running on Windows Server Core.
        • Nano Server may require MS SNMP trap support (wsnmp32.dll) be manually copied to the /system32 folder before Domain Time installation.

        .  Domain Time II Management Tools

        • The Management Tools consist of Domain Time II Manager plus a number of special-use utilities and services.
        • Any tools that calculate comparative time variances (such as Domain Time II Manager, Domain Time II Monitor Service, DTCheck utility, etc.) cannot be relied upon to provide accurate results when executed from a virtual OS. These should be run on physical machines. 1
        • Some functions require file access through administrative file shares and Remote Registry access using Windows Networking.
        • Manager and many of the Management Tools will not run on Nano Server.

          .  Domain Time II Manager

          • Manager requires that Domain Time II Server be installed first. Server and Manager must be installed on the same machine and be the same version.

          .  Domain Time II Monitor Service

          • Monitor can be installed and run from the Manager machine or installed independently on any other physical machine.

          .  Domain Time II Update Server

          • Update Server must be installed on a machine running Domain Time II Manager v5.1 or later.

        .  Domain Time II Audit Server

        • Audit Server requires both Domain Time II Server and Manager. All three components must installed on the same physical machine and be the same version.
        • Audit Server acts as a plug-in to Domain Time Manager and shares its view of the network.
        • Domain Time II Audit Server is not supported on virtual machines. 1
        • The Audit Server machine must have sufficient disk space to hold all audit records and sync logs collected. You may use the Audit Disk Space Estimator to calculate disk usage for Audit Records. Sync log sizes can be estimated based on ~20 bytes of log space per synchronization.
        • Some functions require file access through administrative file shares using Windows Networking.
        • Collected Sync Log files, Daily Audit Summaries, and Audit records cannot be viewed from Audit Server running on Windows Server Core.
        • Audit Server will not run on Nano Server.

        .  Domain Time II Windows Time Agent

          The Windows Time Agent (WTA) is a special-use Control Panel applet for configuring and monitoring the Windows Time Service (W32Time).

        • WTA will act as a snap-in to Domain Time II Server or Client, or will run as a stand-alone utility.
        • Will run on Windows 2000 but with limited functionality.
        • Windows Time Agent will not run on Nano Server.
        • As of v5.1, WTA is no longer included by default in Server and Client installations, but it remains available in the distribution setup files

        .  Domain Time LMCheck Utility

          LMCheck uses Windows Networking LanMan protocols to give a rough variance report of the local subnet.

        • NetBIOS (Windows Networking Browse List) must be enabled on each machine being sampled.
        • Included with the Domain Time II Management Tools. It is also available as a stand-alone freeware utility.
        • LMCheck will not run on Nano Server.

      1 As of Windows Server 2012, Microsoft has made significant improvements in Hyper-V guest clock handling, such that on sufficient hardware, Hyper-V guests may be suitable for running time services such as Domain Time Server, Audit Server, Manager, tools, etc. for general purpose use. Highly time critical environments should (such as those requiring sub-millisecond timing) should continue to use physical machines for these systems. Older Hyper-V environments (i.e. Server 2008) are not suitable for serving time.
