samba - Jan 2003 - Policies with Samba as PDC for a Win 2k-XP client

hi,
first of all i use samba 2.2.5
My Samba is a PDC for 20 box under win2k/winXP
I created a ntconfig.pol with poledit and i put it in the netlogon
directory
The policies of my windows client changed.
Some of the policies was not good so i decided to recreate my ntconfig.pol
and to replace it in the netlogon dir. but the policies didn't change on my
client !
I verified that there was no other .pol on the serveur.

PS :I turned on the automatique update of my policies.(I am not sure this
is that...) and now my client could not find my new ntconfig.pol

help me !! :)
