I need to design a plan for Active directory . in this way visio and Edarw are two software that help me .today i find a new software that automatically generate a diagram like as Visio !
The Microsoft Active Directory Topology Diagrammer reads an Active Directory configuration using LDAP, and then automatically generates a Visio diagram of your Active Directory and /or your Exchange Server topology.
The diagramms may include domains, sites, servers, organizational units, DFS-R, administrative groups, routing groups and connectors and can be changed manually in Visio if needed.
