SNTP is client-only.  It's just NTP without the server-side of things.  So, if
the Windows server is running SNTP, it can't serve time to anyone.

Linux and OS/X can run SNTP clients just fine (and, in fact, ntpdate is
effectively such a client).

Simple test:

What does ntpdate -q your.time.server tell you?  If ntpdate can't talk to it,
then it's either not running an NTP server, or it's filtering out NTP requests
from you.
