From reading newsgroups and public lists, many Exchange customers aren't aware of our Tools & Updates web page.  With Exchange 2003, we actually removed many of the tools from the CD and moved them to the web.  The reason is so that customers would have one place to go for the latest version of a support tool.   We have combined all downloads for a given release on one web page (and in one package), so whenever you have a question like "what is the latest version of <foo tool>", there is one place to go: http://www.microsoft.com/exchange/tools/2003.asp
