Yes. That's the way it's often done. There's usually little need for all
the systems on a LAN to sync to a stratum 2 server. The loss of accuracy
is insignificant, and you still get to have all the Unix/Linux systems on
each LAN sync'ed to the same time with much less than 1 second's
difference.

Samba needs to be running if you want to use the 'net time /set ....'
approach. This method also only sets the time on each system to the
current hh.mm.ss value, where NTP can synchronize times to less than one
second.
There are other WinXX programs available that use methods not requiring
Samba. One called "atomtime" is the only name I remember right now. As
far as I recall it's shareware. You may be able to find others at TUCOWS
or similar shareware/freeware collections.
