We have an Outlook Web Access customisation using Active Server Pages, which fails in an Exchange front end / back end configuration and I would like some clarification of what is supposed to run where. MSDN is not particularly helpful here! I understand that virtual directories must be replicated on both servers, but I would like the ASP to run on the back end server because it needs to access the mailbox store. Using an in-house trace facility shows that our ASP (which is present on both servers) is in fact running on the front end server. Is this right? Should I have empty virtual directories on the front end server? How can I persuade the ASP to execute on the back end server? Thanks, MikeC
