It isn't the dns that needs updating, it the AD dns schema that needs
updating. Before W2k3R2, AD used a different dns schema and when an
early Windows Domain was upgraded the dns should also have been
upgraded, but a lot were not and Windows was happy with this. However,
Samba AD insists on the later dns schema. Follow the info that Louis
posted.
