How do you find out what the Distinguished Name of a server is? I'm installing Office Communicator and it says it should be in format "Example: OU=OU-L-LCS,OU=AppServers,CN=Computers,DC=contoso,DC=com"

i think i figured it out. this article tells how http://technet2.microsoft.com/WindowsServer/en/library/46ba1426-43fd-4985-b429-cd53d3046f011033.mspx?mfr=true"dsquery computer" at the command prompt it think.

Open ADSIEdit.msc -> Go to your server path in Domain Partition -> Go to Properties of server -> Find an attribute Distinguished Name (DN) -> Double Click to open it -> Copy and click cancel in all windows.

Just go to your command prompt (no need for admin mode) and type in dsquery computer- Stefan Camilleri
