Edit Active Directory Description Script
I'm not sure if this is the right section for this, but I thought I would share.
After searching ad nauseam, I managed to piece together a script that allows me to edit the AD Description field using custom tools in PDQ Inventory. Most credit goes to this site for getting me started: http://4sysops.com/archives/automatically-fill-the-computer-description-field-in-active-directory/
I use the field to track location so I can see it in the main display of each collection in PDQ. Obviously you can edit this with your own criteria. Just create a .bat file with "Edit_AD_Description.vbs %Target%" and run it as a custom tool.
