I am trying to find some documentation on this.. and the Admin and User guides don't seem to help.

I need to discover assets on an AD domain.

1) Unfortunately I am a single department of a multi department organization. Active Directory Domain contains multiple OU folders.  I want to scan just 1 OU folder for assets.. not the entire Domain.

I can't find a way to restrict the discovery of assets to 1 OU folder within a domain.

OR

2) Scanning a Network (IP Range), I get about 50% failures -- I think it is a firewall thing, but not sure what ports to open up.

Either any suggestions on how to restrict the AD scan to just 1 folder within a domain

OR

A way to troubleshoot or resolve the IP Range failures.

Thanks
