Method for Synchronizing Domain Controller with Other Network Servers

      Disclosed is a method for synchronizing the clocks of all the
network servers in a domain with that of the domain controller.

      In IBM's OS/2* LAN Server, synchronizing the clock of a domain
controller with the clocks of other network servers in the domain is
a very important feature.  This synchronization feature enables
timely replication of database files from the domain controller to
the other network servers.  Currently, the date and time are
synchronized only when the clock at the domain controller is set
using the NET TIME command of LAN Server.  If the clock at the domain
controller is updated by using the operating system commands or the
application programming interfaces provided by the operating system,
the
update will not be propagated to the other network servers in the
domain.

     A new LAN Server service - timesync - was developed to solve
this problem.  The timesync service is installed only on the domain
controller and it is started automatically when the server service is
started.  It can also be started separately by issuing the "NET START
timesync" command.  It can be stopped by the NET STOP command, but it
cannot be paused or continued.  The service periodically synchronizes
the clock of the domain controller with that of the other network
servers in the domain.  This solution solves the server to server
replication problems associated with drifting clo...
