Trying to pull up Computer Description from Active Directory

Hey all!  First time posting, so please forgive me if I do something out of the norm.  

I am pulling specific data from Active Directory into the Power BI desktop.  I need:

• computer name (all good, I got it)
• distinguishedName of OU's (all good there too, I got it)
• computer description (here's the problem

I am able to find what I need except for the attribute for computer description.  Could anyone please point me in the right direction? 

Thank you!
