export/import active directory

[archi]

We have 3 active directory domains: production domain,
test domain in the lab on the isolated network and test
domain on production network.
We need to keep the same settings on all of them.
Is it any method or tool that allows to export AD settings
from production domain and apply to test domains?

Thank you.

MIIS will allow you to synchronise certain details between domains.
