[Samba] ntpq -p ***Request timed out

I have two DC's running Version 4.1.16-SerNet-Debian-9.wheezy and a
member server running Version 4.1.11-Debian. 

When I 'ntpq -p' from the member server I get: 

localhost: timed out, nothing received
***Request timed out 

Member server ntp.conf file: 

cat /etc/ntp.conf
# Local clock (this is not the localhost address!)
fudge stratum 10

# The source, where we are receiving the time from (PDC)
server dc02.dts***m.lan. iburst prefer
server dc01.dts***m.lan. iburst prefer

driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp

# Access control
# Default restriction
restrict default ignore

# Allow everything from localhost

# Allow that our time source can only provide time and do nothing else
restrict dc02.dts***m.lan. mask nomodify notrap nopeer
restrict dc01.dts***m.lan. mask nomodify notrap nopeer

The ntp.conf from one of the DC's: 

cat /etc/ntp.conf
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /var/lib/ntp/ntp.drift

# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable

# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example

# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server
# pick a different set every time it starts up. Please consider joining
# pool: <http://www.pool.ntp.org/join.html>
server 0.debian.pool.ntp.org iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst

# Access control configuration; see
/usr/share/doc/ntp-doc/html/accopt.html for
# details. The web page
# might also be helpful.
# Note that "restrict" applies to both servers and clients, so a
# that might be intended to block requests from certain clients could
also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery

# Local users may interrogate the ntp server more closely.
restrict ::1

# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
restrict 192.168.1*6.0 mask notrust

# If you want to provide time to your local subnet, change the next
# (Again, the address is an example only.)
broadcast 192.168.1*6.255

# If you want to listen to time broadcasts on your local subnet,
de-comment the
# next lines. Please do this only if you trust everybody on the network!
disable auth

Went to ntp.org to see if I could troubleshoot. Did as they suggested
and got same result. Their troubleshooting page indicated that most
issues are connected to DNS issues between machines. Did some 'nslookup'
from each DC to the member and vise versa. DNS returns correct results. 

Looked to confirm I do NOT have a firewall running on any device. Not at
this time. 

Member server time keeps drifting and I need to correct this. Any ideas?
