List Legacy/Old/Unknown/New domains and controllers worldwide..

Hi,

We have a VPN connecting worldwide global offices.

I need to gather a list of all Legacy, Old, Unknown, New domains (Microsoft) and their domain controllers running worldwide.

Any tool that I can run against these office networks from my location and gather the information (even as I may not have the admin access – yet for these DCs).

Thanks,
Akash
