Directory and Resource Administrator 7.0 SP1
Domains are not available in the 'Select container' dialog box after applying Service Pack 1.
Directory and Resource Administrator (DRA) is incorrectly processing the rules to not include the Domain object.
This is corrected in DRA 7.5 and later. To resolve this issue upgrade to the latest version of DRA.
To workaround this issue, add a domain rule to the Activeview to include the desired domain but no objects in the domain.
