When I import hosts from my AD, I’m able to see each servers description when selecting the servers. But after the servers are imported, and I enable the “Description” field, it’s empty for all hosts..
In order to populate the description field you need to first check the box that says “Import description field” before you click “Add to grid” when importing hosts from AD. This box is visible under the “Add-to-grid options” of the ‘Add hosts from directory’ window.
