samba - Oct 2004 - suse 9.1Doing a node status request to the domain master browser - Cannot sync browser lists.

I changed the ip on my samba 3.0.4 server from using dhcpd allotted 
192.168.0.165 to a static 192.168.0.5
Now my windows clients get a message:
'the specified domain either does not exist or could not be contacted'
but it is contacting the domain because otherwise it would have given me 
an error saying it can't find it.
I have done a gg: search to no avail
please help i am goining on a few hours trying to solve this prob.
i have shut off all machines on the net, restarted the smb box, still 
has this cache. I have modified the hosts file, done various
nmblookup -U server01 -R lfsoffice
if i use another domain name the windoze machines can join the domain.
after i changed the domain name, i left the smb box on for 2 days, 
hoping it would clear the nmbd cache, but it did not.
and i want to keep the lfsoffice domainname.

here is a cut from my messages:
