I am trying to install DNN 4.3.4. I have notified my hosting server and they've readyied my account to accept DNN.I've got MS SQL 2000,default.aspx as a default doc and relevant website permissions activated. Below I detail the main part of the code. I renamed the original development.config file to web.config(as the documentation.pdf advised it as my host only accepts medium trust). I deleted the original web.config and release.config. I deleted the connection strings for SQL Express 2005 as these were not relevant. Custom errors I set to off(in anticipation of an error!) There didn't seem to be any of these errors going on in your forums so I created a new thread.
