Multiple choices here

1) make the windows system the master of time or a unix system. The latter
is easier. I would go for something like

A Unix system as master, 2 slave ntp unix servers looking at the master and
all the other systems looking at the 2 slave ntp servers. Windows 2000 has
standard the option to sync on a ntp server. Windows NT has not. You can
find ntp software for windows NT on the internet. It is not so difficult to
install. But you can also make 2 Windows 2000 servers sync on unix and let
all other windows systems sync on those to Windows systems.

With less as 25 unix systems I won't bother about the slave setup.

2) Windows as a master of time. Syncing unix on windows takes more work. You
can install ntp software on the windows system to make it a ntp server or
you can make some scripts to get the time from the windows system and
addjust the unix system time with it.
At the moment I just use date -a <delta time> by hand at work to keep the
time more or less in sync. It is a long term project to integrate the unix
and windows time in my company. We even have an Unix and a Windows master
DNS server serving the same domain hich gives all kind of interesting side
effects.

I think it is convinient to make the DNS slave servers also the NTP slave
servers.
