Whether pool servers are being configured or a dedicated USNO server, is a
question of policy, but should not make a difference for this problem.

However, having a look at the contents of the OP's ntp.conf file shows an

# Use specific NTP servers
server tick.usno.nav.mil iburst

If you look at the spelling then you see there's a typo:

tick.usno.nav.mil  can not be resolved, this should read:

So the name of the upstream server is simply invalid, and thus ntpd can not
sync to it. And, if you'd misspell the names of the pool servers, the pool
server would not work, either.

This also explains why "ntpq -p" prints "No association ID's returned" (as
reported by the OP in an earlier post), and I'm sure if the OP had done as
I earlier suggested and had had a look into the Windows application event
log he would have seen an appropriate error message which leads into the
right direction.
