Rdisk, WinMSD challenge.

I want to run WinMSD and Rdisk Locally (I must do this locally in order to get all data from WinMSD). Copy it to a central repository on the network. Setup a batch file to discover new servers within a single domain to set this process up automatically for every new server.

I know how to accomplish most of this except how do I get a batch file to discover new servers within a domain without using 3rd party utilities of software.

Is it possible? Any Ideas?

Thanks in advance.
