collector installtion on Domain controllers

I don't recall the specifics, but one option you can use is the LM API to create a new collector and it will provide a download link for that specific collector. So you can write a script to run on the domain controller to tell LM to create a new collector for that server, get the URL, download and install the software.

Note that you will likely need to get the LM API key on to all the domain controllers or have a way for the script to query for it. I would suggest creating an LM API key just for this purpose and then dispose it once the project is done.
