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, Win11, 2016, 2019, 2022
32-bit (x86) and 64-bit (x64) versions available. ARM is not supported. TCP/IP Port Usage
- Linux x86_64 distro running in 64-bit mode. Kernel version 2.6.30 (minimum), version 3.0 or later (preferred),
with systemd init service controller (not the older inet.d "SysV" type)
- Hardware: Typically, any Intel-architecture machine capable of running Windows (32 or 64-bit) or Linux (64-bit) may run Domain Time.
Machines running Server require sufficient memory for packet buffering and maintaining the
number of TCP/UDP connections used (varies by the number of client machines contacted). See Choose the right machine(s) for more info.
Machines running Manager/Audit Server also require sufficient disk space for holding collected audit records (see the Application Notes below).
Specific Application Notes:
Domain Time II Client for Windows (includes DT-Set command-line client)
- Domain Time II Client may be used on virtual machines. Please see How to configure Domain Time on a virtual machine.
- 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.
- Installed disk usage (not including log files): ~ 6.0 Meg
Domain Time II Client for Linux (DTlinux)
Domain Time II Server
- Domain Time II Server may be used with caution on a virtual machine. Please see How to configure Domain Time on a virtual machine.
- 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.
- Installed disk usage (not including log files): ~ 6.4 Meg
Domain Time II Management Tools
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.
- Audit Server is not supported on Windows 2003/2003R2/XP or earlier versions.
- Audit Server will not run on Nano Server.
- Domain Time II Audit Server will provide less accurate results when executed from a virtual OS.
It should be run on a physical machine, if possible. Please see How to configure Domain Time on a virtual machine.
- Audit Server makes numerous UDP and TCP connections to remote machines. You must have sufficient system resources (memory and processing bandwith) to handle the number
of network connections, which increase proportionally to the number of machines being audited. If you use the new PTP Monitor, these requirements can significantly
increase due to the "chatty" nature of the additional PTP protocol and management message traffic.
- 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.
- Installed disk usage (not including log files): ~ 3.6 Meg
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
