Hello Everyone,

Have you ever tried to manually create a diagram of your Active directory or Exchange topology ????

If the answer is Yes, then you will know how tricky it can get in making sure everything is properly covered, drawn in the right place, and of course having to go back and fix. It really can be very frustrating task for all of us.

Or maybe you are a contractor walking into a site for the first time and need to understand their topology. You can ask around and hope that there is someone who knoes, or, you can discover and diagram it yourself (and leave the diagram with them being an instant hero).

If you have tried but got bored or failed and have been putting it off because of all these challenges , then it is probably time to sit down and make a start...

But it doesnt have to be such a chore because Microsoft released a fantastic free application named "Microsoft Active Directory Topology Diagrammer".

With the Active Directory Topology Diagrammer tool, you can read your Active Directory structure through Microsoft ActiveX Data Objects (ADO). The Active Directory Topology Diagrammer tool automates Microsoft Visio to draw a diagram of the Active Directory Domain topology, your Active Directory Site topology, your OU structure or your current Exchange 200X Server Organization.

With the Active Directory Topology Diagrammer tool, you can also draw partial information from your Active Directory, like only one Domain or one site. The objects are linked together, and arranged in a reasonable layout that you can later interactively work with the objects in Microsoft Visio.

The Diagrammer is very flexible and allows the user to include and exclude granular information such as the following:

domain(s) (child etc.)
Site(s )
Administrative Groups
Exchange connectors (Routing, SMTP, X.400, Notes etc.)
Users in the domain(s)
User Count
Global Catalog servers
IP and SMTP Site links
Inter/Intra Site Replication Connections
Number of Mailboxes
Application Partitions
Servers and OS version information (with color coding)


Important Note:

In order for the tool to do a Active Directory discover you need to configure the tool to point to a Global Catalog server in the environment.

This tool has been verified on the following platforms:

Windows Server 2008 R2
Windows Server 2008
Windows Server 2003
