Domain Time II components communicate with each other using UDP port 9909 regardless of what time protocols are used for time synchronization. You should ensure that UDP port 9909 traffic (including UDP broadcasts on port 9909) can pass freely between all subnets.

All components will benefit from a properly configured WINS and DNS environment. This setup allows quick and efficient resolution of individual machine names to IP addresses. There are, however, workarounds for situations where WINS, DNS, or both are not available. IP address resolution uses the standard Berkeley/Winsock gethostbyname() call. To test your network's capabilities, use PING against a NetBIOS name.

For details on the discovery process and NetBIOS to IP name resolution, please see The Discovery Process.

  Domain Time II Server

x86 (32-bit) - Windows NT4/2K/XP/2003/Vista/2008, with TCP/IP installed.   x64 (64-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed. IA64 (Itanium) not currently supported.   Alpha - Windows NT4, with TCP/IP installed. (Domain Time II version 3.2. only). Notes: 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. NT 3.51 can run version 2.1 of Domain Time II Server. If you need this older version, please write to Greyware Tech Support.

  Domain Time II Clients

Windows Clients Full Client, Thin Client, Ultra-Thin Client, and DTSet Command-line Client x86 (32-bit) - Win95/98/ME/Windows NT4/2K/XP/2003/Vista/2008, with TCP/IP installed. x64 (64-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed. IA64 (Itanium) not currently supported. Alpha - Windows NT4, with TCP/IP installed. (Domain Time II version 3.2. only). Notes: DTTray System Tray applet is not accessible when running on Windows Server Core. NT 3.51 can run the Thin, Ultra-Thin, or DTset Clients but not any other components. Win95 requires Winsock2 and either (a) MSIE 4.0 or greater, or (b) version 4.72 or greater of comctl32.dll. These patches are free downloads from Microsoft. NOTE: Only Win95 needs these patches. Win98, ME, Windows NT4/2K/XP/2003/Vista/2008 are ready for Domain Time II already. You may download the Winsock2 upgrade directly from Microsoft, or you may get it from Greyware (provided as a convenience only; see Microsoft's site for support, licensing, and instructions). If you don't already have MSIE 4.0 or greater, you may download it from Microsoft. If you don't want to install MSIE, you may upgrade your common control library (comctl32.dll) instead. You can get the upgrade directly from Microsoft, or you can download 401comupd.exe from us (provided as a convenience only; see Microsoft's site for support, licensing, and instructions). Windows for Workgroups Client (domtimew) Windows for Workgroups 3.11, with NetBEUI, IPX/SPX, and/or TCP/IP installed Intel platform only. The client must share at least one network protocol with its server, and the server must be providing the Domain Time I time protocol.   'NIX daemons Linux Intel x86 Architecture, Kernel 2.2 or later Solaris Version 7 and later on Intel x86 Architecture

  Domain Time II Management Tools

The Management Tools consist of Domain Time II Manager, the Monitor and Update Server system services, plus a number of special-use utilities. They have the following requirements unless otherwise indicated on the Other Tools page:   x86 (32-bit) - Windows NT4/2K/XP/2003/Vista/2008, with TCP/IP installed.   x64 (64-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed. IA64 (Itanium) not currently supported.   Alpha - Windows NT4, with TCP/IP installed. (Domain Time II version 3.2. only). Note: Some functions require file access through administrative file shares and Remote Registry access using Windows Networking.

  Domain Time II Audit Server

x86 (32-bit) - Windows NT4/2K/XP/2003/Vista/2008, with TCP/IP installed.   x64 (64-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed. IA64 (Itanium) not currently supported. Notes: Domain Time II Server must be installed on the same system where Audit Server is installed. The Audit Server machine must have sufficient disk space to hold all audit records and sync logs collected. You may use the Audit 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.

  Domain Time II Windows Time Agent

The Windows Time Agent is a special-use Control Panel applet included with Domain Time II Server and Client services. It is also available as a stand-alone utility.   x86 (32-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed.   x64 (64-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed. IA64 (Itanium) not currently supported. Note: Will run on Windows 2000 but with limited functionality.

  Domain Time LMCheck Utility

LMCheck is a utility included with the Domain Time II Management Tools. It is also available as a stand-alone utility.   x86 (32-bit) - Windows NT4/2K/XP/2003/Vista/2008, with TCP/IP installed.   x64 (64-bit) - Windows XP/2003/Vista/2008, with TCP/IP installed.
