Yup, that's the problem. The network, not this particular hardware, goes
on the road for client demos and into random locations - even up the odd
mountain - so net connectivity is neither guaranteed nor necessarily
easy to get hold of.

It's quite a nice tool - for Windows ;-)
In any case, I've found NTP from these folks:
which has a specific option to failover to the system clock.
Funnily enough, this also glitches when the server is rebooted when off
the net, but either starting the monitoring software or restarting the
NTP service kicks it into life. Since the monitoring software can be
started during a login - which is always going to happen in this case -
that works around the problem - although I've emailed the company to see
whether they can provide a config fix, or whether it's a bug.
Sooo much easier with a Linux box, though :-)
