[ntp:questions] How long do I have to wait for sync?

Hi,

I have been trying to get several internal machines to sync with external 
servers. In my setup, I have one computer (let's call this master) 
connecting to the Internet to synchronize the time. The other computers 
(let's call these slaves) connect to the first computer for synchronization. 
All the computers in this setup are running Windows XP SP2. What I notice is 
that if I start the ntpd service on the slaves shortly (seconds to several 
minutes) after ntpd on the master is started, the slaves do not get 
synchronized right away. The time difference between the masters and the 
slaves before the service was started were within a minute.

ntpq -p on the slaves shows:
remote        refid        st t when poll reach    delay    offset    jitter
===============================================
master.name    .INIT.      16 u  -      64    0         0.000   0.000 
4000.00

ntpq -p on the master shows:
remote        refid                st t  when poll   reach    delay 
offset    jitter
===============================================
LOCAL(1)    LOCAL(1) 12 l  63    64      17       0.000   0.000    0.001
*srv1.netop.org  198.72.72.10 3 u  62  64  17      83.932  2.856   18.006

Config file for master:
########################################
driftfile C:\Docume~1\ntp\Locals~1\Temp\ntp.drift

server 127.127.1.1 iburst
fudge 127.127.1.1 stratum 12

server 0.north-america.pool.ntp.org iburst

########################################

Config file for slaves:
########################################
driftfile C:\Docume~1\ntp\Locals~1\Temp\ntp.drift

server 192.168.0.208 iburst
########################################

How can I get the slaves to sync immediately? Is there anything that I am 
doing wrong? Thank you very much in advance.

Thanks,
Keerati Inochanon
