[Samba] Windows client not accessible when changing ip address on samba PDC

Hi Everybody

 I installed a Samba 3.4.5-3.1 PDC with openldap2-2.4.12-5.3, samba-winbind-3.4.5-3.1,  bind-9.5.0P2-18.1 and dhcp-3.1.1-6.3 on a opensuse 11.1 based on Samba3-ByExample.pdf book.
 I manage a network that has around 60 windows client computers (from windows 2000 to win 7) and quite of them are windows notebooks with 2 NIC's (wireless and cable)
and I was assigning two diferent addresses for each NIC( let's say for wireless: and for LAN cable: through DHCP service.

Problems come when someone that always works well with wireless NIC uses the cable NIC (because poor or no wireless sign) and get back to the wireless NIC ;so change the  notebook ip address from to and back to

I can't access the notebook shared dirs anymore from other windows clients. When trying to access through \\notebook\shared_dir, the windows client get a error like: 'network path not found'. If I do pings to the notebook from other windows cmd: 'c:> ping notebook' it says 'ping to ... request time out'  because the notebook real address is: and not the last taken:  If I do pings or access the share through its real IP address, it works perfectly.

This happens only on windows clients, from linux PDC console either doing pings or connecting to the notebook shares using the computer name works fine anytime.

I don't know why windows clients can't update the other windows ip addresses .

Is there something that a missed on the configuration?
any thoughts?
