Active Directory Topology Diagrammer (ADTD) has been updated! ADTD has been out there for ages and has proven to be useful many times. The UI is very similar to the original one. The DFS-R tab was added to allow DFS-R topologies to be discovered. Exchange 20xx support was added. I did a discover & draw and it seemed to discover everything just nice. Something they added (if I’m not mistaken, please correct me if I’m wrong) is the Exchange schema version on the domain Visio. The Exchange discovery works fine too, however in our environment it failed to draw the number of mailboxes. It seems to draw the amount of mailbox one Exchange 2007 fine (we have some left). But for 2010 it displays 0… The SMTP connectors were drawn perfectly. Definitely a must-have tool for documentation purposes or just to discover anomalies.
