I'm fairly new to exchange server administration, so please bear with me. Our setup, done by someone other than myself, is currently holding only one "site". We are running ASP.NET structure with the APP_CODE folder for codebehind. Unfortunately, all of our sites are basically just pages under a folder tree in this one site. So, if one of our codebehind has a compile error, the whole site has a compile error and dies. Is there a way to setup multiple sites, each with their own APP_CODE/compile process on one exchange server? I've detailed the structures below. CURRENT STRUCTURE - If compile error in APP_CODE, sites 1, 2, and 3 break \\MainServer \APP_CODE \site1 \site2 \site3 PROPOSED STRUCTURE - If compile error in site1, only site1 breaks while sites 2 and 3 remain working. \\MainServer \site1 \APP_CODE \site2 \APP_CODE \site3 \APP_CODE
