I downloaded the Exchange Topology Diagramming Tool from Microsoft’s download center (ExMap.exe). looking for anyone who has used the tool. The docs state that you need to install ADSI and ADO on the server. The docs are not very clear. You wouldalmost belive that these componenets should be installed on the client workstation. I am seeking advice. I downloaded ADSI 2.5 and MDAC 2.1 from Microsoft. I am cautious about installing them on my prodcution Exchange server.
