So far I've managed to add serialnumber and manufacturer in the description field to most computers in the AD, but what I would like to do next is to check each computer if they have already have the info, if not, add serialnumber and description.
All in all
Get computer description
is there already a description? y/n
if yes, continue to next,
if no, add information to description
I apologize if I'm unclear with my question.
