NTP server not working on Windows Server 2003

I am trying to get the NTP server working on windows server 2003 SP2. I have
followed the instructions in KB 816042 "How to configure an authoritative
time server in Windows Server 2003".
Running "netstat -an" returns
UDP 10.9.200.1:123 *:*
UDP 127.0.0.1:123 *:*
so NTP is listening on port 123.

Running "w32tm /monitor" from anywhere on the domain returns
vbiserver_01.corp.vitalbasics.com *** PDC *** [10.9.200.1]:
ICMP: 0ms delay.
NTP: error ERROR_TIMEOUT - no response from server in 1000ms

I turned logging on in the w32time registry settings and I am getting the
following lines in the log when I run "w32tm /monitor"
148660 17:40:31.0396834s - ListeningThread -- DataAvailEvent set for socket
0 (10.9.200.1:123)
148660 17:40:31.0396834s - ListeningThread -- response heard from
10.9.200.89:123
148660 17:40:31.0396834s - Ignoring packet invalid mode combination (in:3
out:0).

I have the registry setting AllowNonstandardModeCombinations set to 1.

Anything between client/server that could be blocking udp port 123? (e.g.
firewalls, acls on routers, .etc)

No. Windows firewall is not enabled. I have also used Network Monitor to
verify the UDP message on port 123 is received by the server. Also I get the
same behavior if I run "w32tm /monitor" on the server itself.

Hmm... if vbiserver_01 is the PDC, is it configured to get time from an
external source?

Found the problem. There was a domain group policy rule that disabled NTP
servers for the domain.
