You problem should come from the web.config which is located in your module folder (i.e. dnnsamplemodule folder). If it doesn't contain any specific information, I recommand you to delete it.
More precisly, the problem is that some settings included in this web.config would override the settings of the web.config of your DNN root folder. Nevertheless, the current configuration of your computer doesn't allow this configuration.
