In ASP. NET, other machines can also see error messages.

In ASP. NET, if the default settings are used, the Exception details can be displayed in the browser only when Excetpion occurs during local access. When other machines access your IIS server, no Exception occurs. Although this mechanism effectively protects the security of the server and ensures that some important information is not leaked, this feature is annoying during the Combined testing in the development phase, the tester may feel inexplicable when an error occurs. How can this problem be solved.

In fact, it is very simple. Just modify the web. config file of ASP. NET. Add the following section to the web tag.

<CustomErrors mode = "Off"/>

Note that the first letter of "Off" here is in uppercase. Do not make mistakes.

Then access your ASP. NET application and expose the error information.
