[Samba] samba 3.0.21a rpc joined domain question

[Lee Rocky]

Dear all

Version: samba 3.0.21a
Server: Windows 2000 mixed  (R2K-PDC)

steps
-- net rpc join domain -U administrator%xxxxx , (success joined)
-- start winbindd => OK
--  wbinfo -u => failed, error message
            kerberos_kinit_password RO120$@R2K-PDC.COM failed: Cannot
resolve network address for KDC in requested realm
ads_connect for domain R2K-PDC failed: Cannot resolve network address for
KDC in requested realm

-- wbinfo -m => disply trust domain?
    R2K-PDC (is it corrent result?)

the same steps and configurations, this error is not happen with smaba
version 3.0.20b

and I found that " wbinfo -m"  after join domain,
the reuslt of 3.0.20b is empty,  wbinfo -u has no problem.
