Only your central server need have an Internet (or radio-clock or GPS/PPS) 
connection.  You specify, say, five servers and NTP will pick the best 
every 20 minutes or so.  Possibly, the router you are using may provide an 
NTP server.  The rest of the PCs simply need a network connection to your 
central server.  There is something called "Orphan mode" in development 
for just such a situation as you describe - no Internet connections - but 
I don't think that is in the Meinberg Windows port right now.  There may 
be a more recent beta available, though.

It's better if you can get some sort of hardware clock available for the 
central server - a GPS18x LVC which has serial output could be affordable 
(less then $100/£100), and near a window with a south view might "see" 
enough satellites.  Then your network is talking UTC (and displaying 
whatever wall-clock time you want).
