[Samba] domain trust problem

[zergio]

Hi all!
I set samba-3.0.4 domain as trusted by windows 2k domain. Users from 
samba domain logon to win2k domain without any problems. However when I 
try to add to win2k group any group from samba domain windows returns 
error and on samba server I got smbd (user nobody) process witch 
consumes half of CPU, does not respond to SIGINT and it hangs like this 
for a week.
