Hi all,
I have configured my 1841 to pickup ntp service as below:
scheduler allocate 20000 1000
ntp clock-period 17178609
ntp update-calendar
ntp server 130.88.200.4
and my switch to set the time locally from the above router on its Fa0/0 port as below:
ntp clock-period 17179885
ntp server 192.168.2.1
end
All the above is working as should be...
But i cant get my windows 2008R2 server to pickup the time from the GW Router (above) on the 192.168.2.1 IP, is there anthing that i need to do on the router to enable this? i have tried setting ntp broadcast on the fa0/0 port on the router but again the sever couldnt pick any time details up. Im not sure if this is possible, as i haven't seen this setup in any production enviroments!
Thanks in advance,
Paul

I've remembered recently that this cannot be achieved as there's some "mis-communication" between Cisco IOS and Windows OS regarding NTP/SNTP.
In my humble opinion, if I may, nominate one (or two) servers to go across the internet to synchronize on an authorized stratum 1 or 2 server and let the rest of your severs synchronize with this.

Thanks for the reply Leo,
I thought as mutch! I have my servers set to sync with a stratum 1 at the moment.
Do you happen to know if Linux distros can NTP sync with Cisco devices?

I must say I haven't tried this out. I have a niggling suspicion it may work. Just ensure you have both NTP and SNTP settings turned on and get Linux ntpdaemon enabled.
