Just an FYI for others who are looking to do this, if you specify the hub that this robot will get the files from, have to provide full path down to the distsrv in the distsrv line I found. Otherwise controller.log says can't find package ***.
Example:
request.cfg:
<distribution request>
packages = WindowsBase_SuperPack1, Pack2, Pack3
distsrv=/DOMAIN/Hub01/RobotName/distsrv
</distribution request>
Place this in your \Nimsoft\ install directory and cycle the robot service. Watch the controller.log for errors. Bump it up to level 3 for more info.
