[ntp:questions] Severe time drift for Undisciplined Local Clock

[deon at nulan.co.za]

Hi All

Thanks for the tremendous response I have received. I have bowed to  
the collective wisdom and have located a  Windows XP machine at each  
of our 200+ sites which we have configured to serve as a Time server.  
It is using the onboard RTC as the source.

I still have a problem though.

I can ping the server and Linux sees it but the time is not synched. I  
have run ntpq and the rv command indicates that the server is  
rejected. Why I cannot establish. The complete log files are attached.  
Anyone else which can offer a reason? BTW, have tried from 2 different  
servers and get the same results so either I am doing something wrong  
or XP has a problem. (The only problem I am aware of on XP is when it  
is used to synch to External Clock Sources).


I am calling ntpd like this:

ntpd -A -l /var/log/ntp/main.log

My /etc/ntp.conf file has one line:

server 192.168.222.100

Any help appreciated!

Deon
