Windows 2000 uses W32Time to synchrone date / time in a Windows 2000 network. In a Windows NT 4.0, Windows 2000 computers would record the following System event:
        Source: W32Time                                      Type: Warning                                      Event ID: 64                                      Description: Because of repeated network problems, the time service has not been able to find a domain                                      controller to synchronize with for a long time. To reduce network traffic, the time service will wait 960                                      minutes before trying again. No synchronization will take place during this interval, even if network                                      connectivity is restored. Accumulated time errors may cause certain network operations to fail. To tell                                      the time service that network connectivity has been restored and that it should resynchronize, execute                                      "w32tm /s" from the command line.
If you synchronize in your Windows NT 4.0 network, using W32Time, you can configure the Windows 2000 computer to participate:

1. Edit the %SystemRoot%\W32time.ini file on the PDC and set LocalNTP=yes.

2. At a CMD prompt on the PDC, type:

    net stop w32time                                  w32time -update                                  net start w32time
3. On the Windows 2000 computer, type:
    net time /setsntp:<PDC Computer Name>
NOTE: If you are using Timeserv, modify the above accordingly.

NOTE: If the Windows 2000 computer ever joins a Windows 2000 domain, you must reset it's W32Time service. Use Regedt32 to navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters. Delete the ntpserver value and change the type value to nt5DS, from ntp.
