Resolution
The "Server Manager" installed features does not include AD DS and AD LDS Tools.
In Server Manager, select "Add Roles and Features Wizard".
Expand the feature "Remote Server Administration Tools".
Select "AD DS and AD LDS Tools" and click "Next" and then "Install".
Reboot the server if needed.
Confirm that the agent can be installed on a machine in the domain that will enumerate.
Try renaming the AA share and running the configuration wizard again.Try adding the domain to the dns suffix search order of the NIC on the AA server as well as an entry in the hosts file for the domain and the IP address of one of the DCs. -
