[c-nsp] OT: NTP windows servers

[Chuck Church]

What was the TTL of the DNS entry?  I'm assuming windows DNS respects TTLs
and re-polls when it expires?

we ended up changing the NTP FQDN to the IP and restarted services and it
fixed it.  It's like the FQDN only gets resolved once and never again.  So
after changing it to the IP I'm guessing I could change back to the FQDN.
 we were just hoping that changing the DNS was going to fix it.
