Changing the Column Set for Network View

I would like to see a couple of columns in my Network View. Thanks to some help on these forums, I know how to change my columns, but I cannot find the exact thing I am looking for.

What I want is Active Directory Computer Description or Location

I have tried:

Under Column Config, My Column Set, Computer, Asset Info 

1. Description
2. Department
3. Location

   Also at the bottom of the list, Computer 

1. Comment
2. Computer Location
3. Description (same as asset info description)
4. LDAP Location

Can anyone help me out with where to find some AD info on my computers?
