[Samba] Strange behavior when join a domain

[Rashid N. Achilov]

Samba 3.0.23c, FreeBSD 6.1-RELEASE, Windows domain on W2K Advanced Server. 
When I have tried to join a domain I had have cought with a very strange 
occassion:

# net ads join -U adminuser -w ASKD
Failed to set servicePrincipalNames. Please ensure that
the DNS domain of this server matches the AD domain,
Or rejoin with using Domain Admin credentials.
Using short domain name -- ASKD
Disabled account for 'SENTRY' in realm 'ASKD.GMBH'

User adminuser is a Domain Admin member, I had have use this login to do a 
kinit, and was succesfull. Computer object created in AD, but stayed 
disabled.

Samba box have Windows DC as a DNS into a resolv.conf

When I had have tried to join as RPC, that was succesful
# net rpc join -U adminuser -w ASKD
Joined domain 'ASKD'

What can I do here? That's don't annoyed me too much, but I'd like, that's all 
will be "as usual". At home I have W2K3 Enterprise Server with FreeBSD 
6.1-RELEASE into a VMWare box, and I have tried much times to join, rejoin 
and so on with different 'mistakes' at settings - anyway join is succesful!
