  • The stack trace reveals a couple of things. One this is a web app and opens up a whole can of worms since permissions come into play. The actual exception is occurring in your btnSave_Click method in default.aspx at line 92. What is that exact line of code doing? Is there an inner exception with more information? Have you verified the permissions for the app pool to actually use WMI?
