When attempting to debug your ASP.NET applications, you may find that the error messages are cryptic or even meaningless. This may be the result of having a specific option set in your Internet Explorer browser. To assist your debugging efforts, you should change this option.

1. In Internet Explorer (assuming you are using IE) choose ToolsInternet Options.
2. Click the Advanced tab.
3. Deselect the Show friendly HTTP error messages check box.
4. Click OK. This turns off friendly messages and provides meaningful ASP.NET messages.
