samba - Apr 2005 - Samba 3 joining Windows 2003 domain problem

Hi all! have been having a lot of trouble with trying to get samba 3
client to join a windows 2003 domain, any help would be greatly
appreciated:

vanilla samba 3.0.14a install on solaris 5.8 in 64bit environment with
openldap and kerberos 5 1.3.2 libraries.

when trying to join the domain, getting 

box# net ads join -Uuser@SOME.DOMAIN.FOO%foo
[2005/04/29 15:26:18, 0] libads/kerberos.c:ads_kinit_password(146)
  kerberos_kinit_password user@SOME.DOMAIN.FOO failed: Cannot resolve
network address for KDC in requested realm
[2005/04/29 15:26:18, 0] utils/net_ads.c:ads_startup(191)
  ads_connect: Cannot resolve network address for KDC in requested realm
box#

part of the snoop off of the same box:
  adc -> box    LDAP R port=37139 Bind Response SASL Bind In Progress
  box -> adc   DNS C _kerberos._tcp.SOME.DOMAIN.FOO. Internet Unknown
(33) ?
  adc -> box    DNS R _kerberos._tcp.SOME.DOMAIN.FOO. Internet Unknown
(33)  


kinit fails on something else, krb5.conf and smb.conf are plain vanilla
out of the documentation.

DNS servers used on the client (box) are windows 2003 ADC (adc).


thanks!
