Error in named configuration

[alexloko]

Hi all!
centos 5.6 ispconfig 3.0.3.3
initially was OK. but when i add a some dns zone to client the error in named appeared and i can`t start named:

[root@myhost ~]# service named start
Starting named:
Error in named configuration:
zone domain1/IN: has no NS records
_default/domain1/IN: bad zone
zone domain2/IN: loaded serial 2011110601
zone domain3/IN: has no NS records
_default/domain3/IN: bad zone
                                                           [FAILED]
[root@myhost ~]#

in spite of this, all web page of this domain is open in browser. I see only the error message in ISPconfig admin panel - "DNS-Server: Offline"

Please - say - it is critical error and what i must do to correct it message and start name service?

Thank You and sorry for my english... (
