Two separate configuration problems are visible from the thread: the browser credential popup (reported by ) and the parser/configuration error later shown by . As suggested, this is either application-level auth or server-level configuration. The parser information strongly suggests a runtime mismatch: the site was published with web.config elements introduced in ASP.NET 2.0+, while the host is running ASP.NET 1.1, so the server does not recognize newer configuration sections.

Practical steps to resolve the framework mismatch:

  • Confirm which ASP.NET version IIS is using. On older IIS (6/5) check the site/virtual-directory Properties → ASP.NET tab; on IIS7+ check the Application Pool’s .NET CLR version.
  • If the required runtime isn't registered, register it from an elevated prompt, for example: %windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i. Caution: running aspnet_regiis on a shared or production host can affect other sites—test on a single-machine/dev box first.
  • Prefer upgrading the host to the framework your project targets. As a fallback, republish the app targeting the older runtime or move connection strings to a format compatible with 1.1 (less ideal).

Addressing the authentication popup:

  • The popup occurs when Windows/Integrated authentication is required at either IIS or in the app config. For development, allow Anonymous access and disable Windows authentication in the site’s authentication settings (IIS → Authentication / Directory Security).
  • If the app is intended to use forms-based authentication, switch the app’s auth mode and supply a login page; otherwise leave Windows auth enabled only when the hosting environment and clients are configured for it (browsers like Firefox will show the native credentials dialog when only Windows auth is available).

Final checks: after changes, load a simple static page to verify IIS serves anonymously, review the ASP.NET error page or Event Viewer for details, and ensure publish target and host runtime match. The posts from and already narrow the root causes—fix the runtime mismatch first, then adjust authentication.

Are you running it from Visual Studio in debug mode? or from "view in browser"?

Or is the site live and uploaded to a web server and giving this error?

Any chance you can provide an example of the code you're using for the authentication popup (minus any user/password sensitive information of course) so we can see what your code is doing and possibly help troubleshoot for you?

Love to help but without more info I'm afraid there's not much to work with here :)

no I want to run it on the web browser not visual studio 2005.This is website is my study project.first i publish that solution and give websharing then try to run that at that time it shows error.

Ok, so what I'm reading is that you are getting this as a result of viewing a published page on a web-server, is that correct?

Again, it would still help to have some code samples provided of the portions of the application that are responsible for generating authentication. Alternately, if your application is not what is causing the authentication request then it is possible that your hosting directory was set up incorrectly in your web-server and is requiring you to log in to the directory which would be unrelated to the application.

As indicated above, it is difficult to troubleshoot without more information so if you can provide some details on the following it might help figure out the source of the problem:

  • Is the web-app hosted locally on your development machine or on an external web-server?
  • Is the directory the web-app is hosted from a password protected directory on your web-server?
  • Is there a portion of your code that requests user authentication within your web-app? If so, can you please share the code so we can see it.

In the end your authentication issue is derived from 1 of 2 places, your application code or your web-server. Knowing which one will majorly narrow down the troubleshooting to solve your problem :)

* yes locally
* not pwd protected
* yes a portion ask the username and password
