Don't know if this is right section of NetPro forum to bring up my problem.
I have 871 router configured as NTP master. It works as a gateway for a small windows network with a domain controller. I want DC to pull the time from the router and configured the router as follows:
ntp source Vlan1
ntp access-group peer 11
ntp access-group serve 1
access-list 1 permit 192.168.1.0 0.0.0.255
access-list 11 permit 126.96.36.199
access-list 11 permit 188.8.131.52
ntp server 184.108.40.206
ntp server 220.127.116.11 prefer
description Internal User's segment
ip address 192.168.1.1 255.255.255.0
ip access-group vl1-in in
no ip redirects
no ip unreachables
no ip proxy-arp
ip nat inside
ip inspect FW in
ip tcp adjust-mss 1452
ip access-list extended vl1-in
permit tcp host 192.168.1.10 any eq smtp
deny tcp 192.168.1.0 0.0.0.255 any eq smtp
permit ip any any
Domain Controller is configured according to Microsoft recommendations and I believe they are correct. This is what happens when DC starts synching with the router (I debugged NTP on the router)
174073: Aug 22 18:53:29.348: NTP message received from 192.168.1.10 on interface 'Vlan1' (192.168.1.1).
174074: Aug 22 18:53:29.348: NTP Core(DEBUG): ntp_receive: message received
174075: Aug 22 18:53:29.348: NTP Core(DEBUG): ntp_receive: peer is 0x00000000, next action is 5.
174076: Aug 22 18:53:29.348: NTP Core (NOTICE): ntp_receive: dropping message: AM_NEWPASS, auth error..
My question is what kind of authentication should I configure on the router?
Kindly and hopefully
