Copied Roweland's DC ntp.conf file into my two DC's. Restarted (all)
ntp. Member still timing out! 

(I am starting to think that there is 'something' about the sernet
packages that "they" do differently.) 

Rowland, Could I ask you to copy the ntp.conf from your client (appears
to be your laptop) so I could review it's contents?

Not sure what you mean about removing "server 0.debian.pool.ntp.org iburst" lines. Those on the DC's. Aren't they necessary? Running 'ntpq -p' on DC's results in correct response. --- ------------------------- Bob Wooden of Donelson Trophy 615.885.2846 (main) www.donelsontrophy.com [1] [3 [1]] "Everyone deserves an award!!"

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.

You do not seem to have this line in your ntp.conf:

ntpsigndsocket /var/lib/samba/ntp_signd/

and what is the '*' doing in these lines ?

restrict 192.168.1*6.0 mask notrust
broadcast 192.168.1*6.255

This is my ntp.conf from a DC:

fudge stratum 10
server 0.pool.ntp.org iburst prefer
driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp
ntpsigndsocket /var/lib/samba/ntp_signd/
restrict default kod nomodify notrap nopeer mssntp
restrict ::1
restrict 0.pool.ntp.org mask nomodify notrap nopeer

and with this, I get this from a linux client:
