A little known resource, the Active Directory Component Jigsaw has finally released to the web as a PDF. Its about 8 Mb in size but should blow up to print out very nicely on A3 or right up to A1 posters. Its a poster that diagrams all the pieces of Active Directory and is accurate up to Windows Server 2003. It was designed and produced by a Microsoft Consulting Services couple (Martin and Astrid McClean) of Microsoft Australia.
