dynamic Bind9 and multiboot OSes computers

[olidel olidel]

Hello,
    I have configured a DNS server (bind v 9.0) on a Mandrake 10.1 computer and I've got a problem with the updates of my DNS with my computers which are doing multiboot  (windows xp, windows vista beta, win nt4, different linux version kubuntu...). The update of the A record and also the reversed zone (although in this case it is not so important) is not done correctly when I'm booting from linux to win xp. So, in fact I would like to know if it is possible to keep the same computer name and to have the DNS server updated correctly and dynamically with DHCP (I didn't find any clear answer on this on the internet). If it is possible I would like to know what are the different steps to achieve this goal. You will find below my dhcpd.conf and named.conf files and also the error message that I receive when I'm booting from linux to win xp.

Thank you

O.D.

the error messages :
 
 update unsuccessful: ordi02.nowhere.com: 'name not in use' prerequisite not satisfied (YXDOMAIN)
 update unsuccessful: ordi02.nowhere.com/TXT: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET)
