Here’s a tip for when you are troubleshooting web applications on an IIS server that I’ve found useful over time.
When you access the web application from a client machine, the default Internet Explorer setting is designed to give the user friendly messages that really don’t give much detail.
However if you turn off the Friendly messages then you get a whole lot more valuable information that will really help you figure out what is wrong.
To turn off Friendly HTTP error messages use this procedure.
- Go to Tools > Options and then the Advanced Tab.
- Scroll down till you find the “Show friendly HTTP error messages” option and disable it.
