SUMMARY

This article describes the process by which a client computer attempts to synchronize with a time source server and how it locates that server.

MORE INFORMATION

A Time Source server actually advertises itself through the browser function. You can obtain of list of the services running on a computer using the BROWSTAT utility from the Windows NT and Windows 2000 Resource Kits. To obtain this information, perform the following steps:

  1. Obtain a list of all active transports by typing the following command:

    BROWSTAT STATUS [-v] [Domain]

    This will return a list similar to the below:

       Status for domain DOMAIN_NAME on transport \Device\NwlnkIpx
       Browsing is active on domain.
         Master browser is running build 1057
       1 backup servers retrieved from master DOMAIN_NAME
                            


    NOTE: You will have a listing like the above for each transport available.

  2. List servers participating in browsing and show services available.

    BROWSTAT VIEW <transport>

    In Windows NT 4.0, for example, BROWSTAT VIEW \Device\Netbt_TCP/IP

    In Windows 2000, for example, Browstat View 1 (There are numbers that correspond to the device\transport.)

    This will return a list similar to the below:

       Remoting NetServerEnum to \\FLAXON on transport
       \device\Netbt_TCP/IP with flags ffffffff
       7 entries returned.  7 total. 20 milliseconds
    
       \\ADMHAYN        NT   03.51 (W,S,NT,TS,PBR)
       \\AMINGRAH       WFW  04.00 (W,S,WFW,PBR)
       \\AGROBER        NT   03.51 (W,S,NT,PBR,MBR)
       \\ASTROLL        NT   04.00 (W,S,NT,TS,PBR,BBR,MBR)
       \\BATCAVE        NT   04.00 (W,S,NT,PBR,MBR)
       \\BTSHEET        NT   03.51 (W,S,NT,PBR,MBR)
       \\BTWAY          NT   04.00 (W,S,NT,PBR)
                        

NOTE: See the Rktools.hlp file for details on all of the BROWSTAT flags. The "TS" entry shown above for the 1st and 4th entries is for the Time Source service.
