Could not load file or assembly 'AjaxControlToolkit, Version=1.0.10301.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies. Access Denied (Zugriff verweigert)

Review the permissions of the user that you're trying to impersonate.

In my situation, I was only getting the error on my development machine, rather than on our staging or deployment servers. (For while I got around this by removing the 'identity' node from web.config in my dev environment and just adding the line in post-build so it wasn't a problem anyone other than me.

Migration from Visual Studio 2008 to 2013 : Website is not running (throwing access denied error)

Migration from Visual Studio 2008 to 2013

Without any code changes I successfully migrated from VS 2008 to 2013 but when running website from VS 2013 I got below error.

Server Error in '/' Application.
Access is denied.
Description: An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL.

Error message 401.2.: Unauthorized: Logon failed due to server configuration. Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server. Contact the Web server's administrator for additional assistance.
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18408

Change the below settings to make everything works.

1. Goto Project properties (F4)
2. Update AnonymousAuthentication to Disabled
3. Update WindowsAuthentication to Enabled

Another way also u can change the settings
Go to "\My Documents\IISExpress\config\applicationhost.config" folder and update anonymousAuthentication to be false and the windowsAuthentication mode to true.

System.InvalidOperationException: The path / could not be assigned report viewer (Der Pfad / konnte nicht zugeordnet werden)

Report Viewer and (Vista x64 or Windows 7 64 bit)
I have the following problem:

1. Create a new website
