Domain Time II Manager
Version 5.2

Using the Manager Interface

The Domain Time II Manager window is divided into two main Panes:

  • The left-hand Pane Tree Pane (Tree) contains a selection tree showing the various machine and report lists.
  • The right-hand Pane Details Pane (Details) shows detailed information on the item selected in the Tree Pane.

Tree Pane Tree Pane
The Tree Pane consists of three machine lists (four if Audit Server is installed), and several additional informational sections:

    Domains and Workgroups Domains and Workgroups
    This is a list of known machines on the network, grouped by domain. This list is useful for identifying machines on which to install Domain Time for the first time. This list is semi-persistent.

      The list is derived primarily by enumeration from Active Directory (if available). You can also supplement this list by enumerating the Windows Networking Browse List. This list will also show any machines running Domain Time discovered by multicast/broadcast. See the Discovery page for details on how machines are enumerated and discovered.

      • Machines enumerated from Active Directory or the Browse List are cached and will persist as long as they continue to be present in those lists. Manager can be set to automatically remove or tombstone machines that are removed from Active Directory (see Computer List Enumeration for details.

      • Add Computer to Domains Machines not automatically enumerated or discovered can be manually added to individual domains this list. To manually add a machine, highlight the desired domain in the Tree and right-click to select Add Computer… from the context menu. Manually-added machines will persist until manually removed.

      • Machines may be manually removed from the list by expanding the tree list in the left-hand column (or in the right-hand column in recent versions), then right-clicking the the machine name and choosing Remove from cache from the context menu. However, if the machine is rediscovered/re-enumerated by any discovery method, it will reappear in the list.

      • Large numbers of machines may be added or removed from the cache using batch files (see the Batch Add section below)

      • Any machine marked as Audited (if Audit Server is installed) will persist, even if the machine is later removed from Active Directory or it disappears from the Browse list.

      • To rediscover/re-enumerate machines in a particular category, highlight the category in the Tree and choose Action -> Refresh from the menu or right-click and choose Refresh from the context menu. To rediscover/re-enumerate all machines, highlight the top-level Domains and Workgroups item and choose Refresh.

      Unknown, Uncategorized, and Hidden machines
      Machines will show up in this list as unknown (greyed-out) if it cannot be determined that Domain Time is present on the machine (such as if the Domain Time service is not installed, not started, not responding to multicast/broadcast discovery, etc.). If the machine is later determined to be running Domain Time, the details for this machine will be updated and the icon will change to show the running Domain Time machine type.

        Edit Domain Manager makes a best-guess at categorizing machines into their proper domain. If the domain cannot be identified, machines will be listed as Uncategorized. A machine can be moved manually to any domain category by highlighting it in the Tree, then double-click to edit the Domain field on its Details Pane.

        You may choose to hide machines on the list by right-clicking the computer name in the Tree and choosing Hide Computer from the context menu (or by double-clicking the Hidden editable field on the machine's Details pane).

        You can toggle whether to temporarily display all hidden machines by selecting the Show Hidden Computers item on the View menu. Hidden machines displayed this way will be shown with a strikethrough font in the Tree list.

        If you want to reset the hidden flag on all systems to the default setting, choose View -> Unhide all Hidden Computers from the menu.

    Domain Time Nodes Domain Time Nodes
    This list shows all machines discovered to be up and running Domain Time when the list was last refreshed. This list is useful for showing current variances, statistics, and other Domain Time-specific information.

      You cannot manually add machines to this list. The machines that appear in this list are discovered either by multicast or broadcast scans. See the Discovery page for details on how to configure Domain Time II machine discovery.

      Refresh Domain Time Nodes List This list is not persistent. It will be updated each time the program is started (if desired, see the Network Options page) or when the list is manually refreshed. To refresh the list, highlight the Domain Time Nodes category in the Tree and choose Action -> Refresh from the menu or right-click and choose Refresh from the context menu.

      If a new Domain Time II machine is found by multicast/broadcast, it will appear in this list and also be added automatically to the Domains and Workgroups list above. If a record already exists for the machine there, it will be updated with current information. Note, although you may mark a machine as Audited on the Details pane for a machine in this list (assuming you have Audit Server installed), the record for the machine will only persist in the Domains and Workgroups list.

      It's quite possible to get multiple entries on this list from a single machine, since there may be more than one IP address and more than one Domain Time Component installed on a machine. Each of these may send a reply to the discovery packets, resulting in duplicated entries. You can toggle whether to show all responses or hide the duplicated items by clicking the Show Duplicate DT2 Responses item on the View menu.

    NTP Nodes NTP Nodes
    This list shows all machines that respond to standard NTP time requests that have been discovered by multicast/broadcast or that were manually-added to Manager. This includes machines running ntpd or chrony on Linux, or other NTP daemons on other platforms. Even Domain Time Servers that have NTP enabled will appear on this list.

    This list is useful for displaying the current variance of your NTP machines, and to select which NTP machines to audit (if you have Audit Server installed).

      Machines newly discovered by multicast/broadcast will be added each time the program is started (if desired, see the Network Options page) or when the list is manually refreshed. To trigger a new discovery scan, highlight the category in the Tree and choose Action -> Refresh from the menu or right-click and choose Refresh from the context menu.

      This list is always persistent. No machines will be removed unless you manually delete them.

      To manually add single NTP machines to the list, highlight the NTP Nodes category in the Tree pane, then right-click to select Add NTP Node… from the context menu. Enter the DNS Name or IP address of the NTP Node on the Add Machine dialog.

      Large numbers of machines may be added or removed from the cache using batch files (see the Batch Add section below)

    PTP Nodes PTP Nodes
    As of version 5.2.b.20170101, this category will appear when Audit Server is installed. If PTP Monitor is enabled (it is off by default), this list shows all PTP nodes discovered by Audit Server's powerful PTP Monitor process. Using PTP Monitor, you may discover, audit, and track the availability of virtually any PTP device on your network, regardless of platform or manufacturer. Read more about PTP Monitor.

      This list is useful for displaying the current node identifying information, time deltas, up state, and to select which nodes to audit. Right-click the column titles to customize which information is displayed in the list.

      Newly discovered nodes will be added each time Manager is started, when the list is manually refreshed., or when an audit runs. Discovery sweeps may also be set to run on a regular basis if desired, see the PTP Monitor Configuration page.

      This list is persistent. Machines will not be removed unless you manually delete them, or if you have enabled auto-removal of non-responding nodes on the Configuration page.

    System Information System Information
    Click this category in the Tree to show important information about the system running Domain Time II Manager (this is also the same information shown when you select Help -> About Domain Time II Manager... from the menu).

    There are two other items contained in the System Information category:

      Info Item Reference Time shows the current status of the reference clocks selected on the Options -> Reference Time page. Click here for more information on configuring Manager's Reference Time.

      Info Item License Report shows the license status of all known Domain Time components.

        The remaining time on any evaluation versions will be displayed, otherwise machines will be shown as registered, along with their current version information and install dates.

        Summary information displaying the totals of each type of license appears on the status bar on the bottom of the Manager window.

        You may export this report using the File -> Export List... command on the menu.

    Conflict and Problems Conflicts and Problems
    Items will appear in this category if a problem is detected by Manager.

      For example, a conflict will be flagged if Domain Time machines are detected running with the same Domain Time serial number. Domain Time serial numbers must be unique.

      In most cases, you can resolve the conflict by highlighting the conflict item Duplicate Serial Numbers in the Tree and double-clicking the Repair link on the Details Pane. This will bring up the Reset Duplicated Serial Numbers dialog which lets you select which machines to renumber.

      Domain Time II Manager - Reset Duplicated Serial Numbers dialog
      Domain Time II Manager - Reset Duplicated Serial Numbers dialog   [Click for larger size]

      If you are unable to correct the conflict using this utility, you will need to manually correct the serial number on the machines:

      • On Windows machines, run the following command as administrator from the command-prompt on one of the affected machines:

          dtcheck /resetserial

      • On Linux and UNIX machines running domtimed, the serial number is derived from the HOSTID variable. Each flavor of 'nix sets this value in its own way; you will need to research how to change the HOSTID value for your particular system.

    Real-Time Alerts Real-Time Alerts
    This category shows you any Real-Time Alerts reported from Servers and Clients. Real-Time Alerts are configured and collected by Audit Server.

    Audit Server Audit Server
    If you have installed Audit Server, this category will appear and show you summary information about the service.

    There are two other items contained in the Audit Server category:

      Info Item Synchronization logs shows you all machines for which you have collected Synchronization (Drift) Logs. You can double-click on the machine's name in the Details Pane to display its Drift Graph.

        You can also see this information from the Audit Server -> Synchronization Logs menu item. You can also Right-click to choose Open Containing Folder from the context menu if you want to browse the actual log files using Windows Explorer.

      Info Item Audit Results shows a list of the most recent audit runs. Double-click the name of the audit in the Details Pane to display the complete Audit Record.

        The number of results shown is configurable using the Options -> Appearance and Interface -> Interface Options menu item. You can also Right-click to choose Open Containing Folder from the context menu if you want to browse all of the audit results files using Windows Explorer.


Tree Pane Details Pane
The Details Pane will change to display information on the item selected on the Tree Pane.

    If the selected Tree item is a single machine or topic, individual statistics and information about that machine will be shown.

    Information in the displayed Details Pane can be updated by clicking Action -> Refresh from the menu or by right- clicking and choosing Refresh from the context menu.

    If the Tree item is a category that contains multiple items, you’ll see either summary information or a table display showing the items.

    You can also control how Manager displays items, fields, and lists using the Options -> Appearance and Interface menu item.


    Table displays are highly customizable. You can control which columns are displayed, and in what order. You can also sort the table list by any column, making it very easy to see all the machines running a particular version, which machine has the worst variance, etc.

       [Click for larger size]
      To change which columns are displayed, right-click on any column header. You can pick from a list of all available columns.

      To re-arrange the order of displayed columns, grab the column header and drag it to the desired position. Manager will remember your selections.

      To sort a column, just click on its column header. Click again to change the sort order.

      You may reset any view to the default settings by selecting the View -> Reset Column Layout from the menu. You may reset individual views or reset all views.

    Editable Items

    The Details Pane will often contain fields that can be edited for selected machines, such as whether a machine is Audited (if Audit Server is installed), Hidden, etc. You may also change a machine's domain name, DNS name, location (if an NTP Node), etc. You can edit these fields by double-clicking them (this default behavior may be modified to be done via a single-click on the Options -> User Interface Settings menu page).

    Export List

    Most displays in the Details pane can be exported to a file using File -> Export List... from the main menu.

      For example, you could export the current list of NTP Nodes to a comma-delimited text file (.CSV extension) for later import into a database, or export the License Report to an XML file for use in Excel, etc.

      Exports can include only the visible columns in the Details pane, which allows you to easily select which data to include, or you may choose to include hidden columns as well (there is a checkbox for this on the Save As dialog).

      You may export to CSV (comma-separated value), XML, or HTML formatted files.

Backup/Restore Database

As of version 5.2, Manager can backup and restore its database using the File -> Backup Database and File -> Restore Database commands from the main menu.

    You may choose to save the backup files in any file location you want, however, any files you want to restore must be located in the \Program Files\Domain Time II\Backups folder on your system drive.

    Database backups are not intended as comprehensive disaster recovery files. Database backups only include information related to individual machines, such as whether particular machines are audited, machine type, etc. The backups do not include information that is kept in the registry, such as Manager's own settings, or Audit Server schedules, alert settings, email configuration, etc.

    Backups are primarily for making working copies of the database, such as when making large-scale changes or transporting audit lists to another Manager/Audit Server.

Batch Add
Manager also allows you to add/remove machines in a batch from a text file. This is done by entering the following command from the command-line:

    dtman import [full path]\filename.txt

    The %ERRORLEVEL% result is zero if the file was parsed without errors or warnings. If %ERRORLEVEL% is non-zero, you should examine the Manager logs (Options -> View Log File from the Manager menu, or open \Program Files\Domain Time II\Text Logs\Manager.log with a text editor) to see the errors or warning messages.

    The text file format is very simple:

    SYNTAX: [add|drop|delete] [dt2|ntp|all] [ipaddress|name]

    add all
    - sets any existing unaudited machine to audited
    add ntp identifier
    - adds NTP machine to database and sets it to audited
    add dt2 identifier
    - adds DT2 machine to database and sets it to audited

    drop all
    - sets any existing audited machine to unaudited
    drop ntp ipaddress
    - sets existing NTP machine to unaudited
    drop dt2 netbiosname
    - sets existing DT2 machine to unaudited

    del all
    - removes all records from the database
    del ntp ipaddress
    - removes existing NTP machine from the database
    del dt2 netbiosname
    - removes existing DT2 machine from the database

    Adding a machine (or setting an existing machine to audited) can use any kind of identifier that resolves to an IP address. You may use a plain NetBIOS name, an IP address, or a DNS name.

    Dropping or deleting machines, however, requires that you use the exact name by which the machine is known to the database. For NTP machines, this is the IP address (either IPv4 or IPv6). For DT2 machines, this is the NetBIOS name.

    Use the all options with great care, particularly the drop all command. Batch imports take effect immediately and cannot be undone.

    Comment lines are ignored. A comment line is any line whose first non-whitespace character is a pound sign (#), a glitch ('), a slash (/), or a semicolon (;). Blank lines are also ignored.

    The text file should be CRLF terminated. If you are importing from a *nix operating system, be sure to transform the line terminators to full CRLFs.

    Example import file:

    # this is an example
    add     ntp
    add     dt2    PDC01
    add     dt2
    drop    dt2    pdc03
    add     ntp
    delete  dt2    pdc04
    delete  ntp
    # end of list
