Question : Domain controllers inventory

Is there a software out there (hopefully free) that would analyze my domain controllers environment and provide me how it is configure and layout.  I want to be able to gather DC assessment report about how the domain controllers are layout. I know this can be done manually but I do not have time or resource available.

Thanks in advance.

The active directory topology diagrammer would be the first tool I'd use, will draw it out for you in visio
