So you are trying to automate the install of MOSS 2007, and you need to look at the reference for the syntax for config.xml . You do a search on microsoft.com for config.xml, and find this document: http://technet2.microsoft.com/windowsserver/WSS/en/library/2211ed65-a4f3-4a55-9d51-f7842bf386121033.mspx?mfr=true . You’ve found what you are looking for, right? Well, almost. You really want http://technet2.microsoft.com/Office/en-us/library/003e5316-1018-4949-ac54-42fa12c5e51e1033.mspx?mfr=true . Both are the syntax references for config.xml, but one is specific to WSS 3.0 alone, and one is specific to MOSS 2007. For example, APPLICATION is not a choice for server role in WSS 3 but it is for MOSS 2007.
