Why do you want to do this, Juan?  NTP will automatically adjust the 
interval between contacts to the server according to its own needs, and 
you don't normally need to set this.  If you /really/ need to do this, you 
could edit the ntp.conf file with notepad to have entries similar to this:

server    <lan-address>    maxpoll 8    iburst

server    <internet-address>    minpoll 10
server    <internet-address>    minpoll 10
server    <internet-address>    minpoll 10
server    <internet-address>    minpoll 10

This sets the LAN-server to poll not less than once every 256 (2^^8) 
seconds, and have backup Internet servers which are polled at not less 
than 1024 (2^^10) second intervals.
