Deploy OCS NG Agent to more than 500 client systems

Hi
I am using OCS Inventory NG 2.3 in my setup. I happen to read this link  http://wiki.ocsinventory-ng.org/index.php?title=Documentation:DeployTool. Any other alternative to auto discover all the clients in the network instead of adding OCS NG agent on every client machine using Deploy tool since adding agent on almost 500 machines is cumbersome and any way to automate it.
Please suggest.

Thanks in Advance
