THIS PAGE REFERS TO AN OLDER VERSION OF DOMAIN TIME.
CLICK HERE FOR INFORMATION ON THE CURRENT VERSION.

 Documentation\Configuration\Clients\Windows\Ultra Thin Client\Registry Settings
    The information on this page refers to the Domain Time II Ultra Thin Client only. See the Full Client Registry Settings or the Thin Client Registry Settings pages for information on the registry entries for those products.

    The Domain Time II Ultra Thin Client does not have a control panel applet. Most settings can be changed remotely using Domain Time II Manager, but some can only be set by changing the registry. This section explains all of the registry entries used by Domain Time II Ultra Thin Client.

    Caution:
    Modifying Registry entries requires basic familiarity with the Windows Registry and its operations. Incorrect changes to the Registry can result in unpredictable, perhaps non-repairable, damage, up to and including a non-bootable system! Have a qualified technician make the changes for you if you are not comfortable with the process. We cannot be responsible for registry problems.

     
    Domain Time II Ultra Thin Client registry settings are located in:

       HKEY_LOCAL_MACHINE
          Software
             Greyware
                Domain Time Client
                   Parameters

    Notes:
    Set Processor Affinity
     
    REG_DWORD
     
    0
     
    00-FF (hex)
     
    If not present or set to zero, Domain Time will not attempt to restrict time-sensitive operations to any particular processor in a multi-processor system. In some systems, the majority of hardware interrupt handling occurs on only one processor (typically processor 0), so it may provide increased accuracy if Domain Time uses only other processors during time-sensitive operations. This value is a hex bitmap representing the processors in the system, with bit 0 representing the first processor, bit 1 representing the second processor, and so forth.
    Value Name:
     
    Value Type:
     
    Default Data:
     
    Range:
     
    Notes:
    Set Timer Resolution
     
    REG_DWORD
     
    0
     
    0-16
     
    If not present or set to zero, Domain Time will use the system-default best-available timer resolution. If set to any other value, Domain Time will use timeBeginPeriod(x) and timeEndPeriod(x) before and after any time-sensitive calculation. In general, this value should either be zero or 1.
    Value Name:
     
    Value Type:
     
    Default Data:
     
    Options:
     
    Notes:
    Windows Time Agent Startup Check [version]
     
    REG_SZ
     
    True
     
    True or False
     
    This value is created the first time a new or upgraded version runs. If not present or set to False, Domain Time will check the domtime.ini file for instructions about overriding the handling of the Windows Time Agent Control Panel applet. If set to True Domain Time will use the current settings. You may set this value to False to force a one-time re-read of the domtime.ini at next startup.
    Value Name:
     
    Value Type:
     
    Default Data:
     
    Options:
     
    Notes:
    Force Windows Time State
     
    REG_SZ
     
    varies
     
    May be blank, Not Touched, Disabled, NoSync, NTP, NT5DS, or AllSync
     
    Controls how Domain Time interacts with Windows Time when the Domain Time service starts.

    If set to Disabled, Domain Time will make sure the Windows Time service is disabled and not running.

    If blank or set to Not Touched, Domain Time will not check or change the operation of the Windows Time service.

    If set to any other value, Domain Time will make sure the Windows Time service is enabled and running, and that its sync type is set to the specified value.

    Value Name:
     
    Value Type:
     
    Default Data:
     
    Options:
     
    Notes:
    Force Windows Time Agent Disable
     
    REG_SZ
     
    Not present or False
     
    True or False
     
    If not present or False, the Windows Time Agent portion of the Windows Time Agent Control Panel applet will use the default or control-panel set options to determine if Agent should be running. If set to True, Domain Time will ensure that the Agent portion of Windows Time Agent Control Panel applet is not running.
    Value Name:
     
    Value Type:
     
    Default Data:
     
    Notes:
    Clock Adjustment Locked Rate
     
    REG_DWORD
     
    0
     
    If zero or not present, overall system slewing will analyze the clock drift and adjust the clock rate to minimize future corrections. If set to any other value between 80% and 120% of the default clock rate, overall system slewing will set the clock rate to the given value and not analyze the clock drift further. Values below the minimum or in excess of the maximum will be ignored. Useful chiefly if the clock rate (also called Phase Adjustment) regularly changes within a small range and you want to select the best rate manually.
    Value Name:
     
    Value Type:
     
    Default Data:
     
    Range:
     
    Notes:
    Clock Change Sensitivity
     
    REG_DWORD
     
    0
     
    0-255
     
    If not present or set to zero, Domain Time will use a value of 2 on NT-class systems, and a value of 10 on Win9x systems. This value represents the number of seconds the system clock must differ from the expected value in order for Clock Change Monitor to decide an unauthorized change has been made to the system clock.
