Archive Manager cannot enumerate objects outside of the domain that it was installed in.
Example: one forest root parent domain and two child domains. Archive Manager is installed in one of the child domains and will only enumerate objects within that domain. No objects within the other child domain or the parent domain will be enumerated by the Active Directory Connector Service.
It is recommended that Archive Manager be installed in the root domain and the attached document be reviewed and followed before the installation. If you have any questions concerning the attached documentation please contact Quest Support.
The domains.xml file can be used to enumerate OUs and Multiple Domains.
