The return of the son of Visio Network Topology Diagrammer
The Microsoft Active Directory Topology Diagrammer is back in a fresh new release from June 2011, a must-have tool for anyone with an AD infrastructure beyond the basic setup that wants to get a birds-eye view of their AD topology with the click of a button.
Requires Microsoft Office Visio and lots of coffee :)
While you're at it...why not also give the Microsoft IT Environment Health Scanner a whirl or listen to the gospel of the AD Rappers using the Risk and Health Assessment Program for Active Directory (ADRAP) Scoping Tool. Word.
