ASP.NET IIS 7.5 Error, Access Denied

Question

We recently moved an ASP application from running on an IIS 6.0 web instance to a separate IIS 7.5 instance. When we invoke one of the functions that does PDF file manipulation and then emails the file we get the following error and we are unsure how to resolve:

Server Error in '/' Application.

Access is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

在IIS服务器配置中的权限菜单下（通常位于右侧），添加所有人或匿名身份验证，您的错误将可以。

Try Enabling the Anonymous Authentication of your Site folder . I too had the same problem and it worked for me .
