We are upgrading an asp.net 1.1 (.net 1.1) application to .Net 2.0 framework. This application has code which runs both classic asp code (with VB6 dlls) and asp.net (with VB.Net) code. During the develoepement phase, we installed vs.net 2005 in the developement machines and made few changes in code to match the requirements in .net framework. We upgraded the QA server - installed framework 2.0 on it and then deployed the code on it. Now we are seeing issues related to security and permissions. I have a few questions. 1. Does the framework upgrade rewrite all the framework security configuration settings ? 2. Does the framework upgrade reset the permissions for the ASPNET account ? 3. is there anything to worry about machine.config ? since there will be a new machine.config for the 2.0 framework 4. is a reboot required ? 5. There framework upgrade did not include the installation of Framework configuration utility (control panel -> adminstrative tools - > MS Framework configuration utility ). Should we do this manually ? Appreciate your help. Thanks, - Anand
