First make sure that the Windows Time Service has been disabled.

You didn't say where you got your version of ntp or what version it is.
Is this the one that Meinberg has made available?

Please post your ntp.conf file.

When you say that the time source of this box is the local clock do you
mean that you do not have any external sources? If so it will take time
before it decides to use the local clock and make it available. That's
by design. If this is your configuration is there a reason why you are
NOT using external ntp servers as time sources?
