SYMPTOMS

When you request a WebForm in Internet Explorer from the Bin folder of an ASP.NET Web application, and your computer is running Windows Server 2003, the WebForm appears successfully (you do not receive an error message). However, when you request the WebForm from an application that is hosted on a computer running Windows 2000 or Windows XP, you receive one of the following error messages:
The page cannot be displayed
-or-
HTTP 403.1 Forbidden: Execute Access Forbidden

CAUSE

By default, when you create an ASP.NET application on a computer running Microsoft Internet Information Server 5.0 (IIS 5.0), the Execute permissions for the Bin folder in IIS are set to None. Also, the Bin folder does not have Read permissions in IIS. Because of these settings, you receive an error message when you try to gain access to a WebForm in the Bin folder.

By default in IIS 6.0, the Execute permissions of the Bin folder are set to Scripts only. Therefore, you can gain access to the WebForm that is located in the Bin folder of your Web application.

WORKAROUND

To work around this problem, set the Execute permissions of the Bin folder in IIS 6.0 to None. To do this, follow these steps:
  1. Click start, and then click Run.
  2. In the Open text box, type inetmgr, and then click OK.
  3. Expand (local computer), and then expand Web Sites.
  4. Expand Default Web Site. Locate your Web application, and then expand it.
  5. Right-click bin, and then click Properties.
  6. Click the Directory tab. In the Execute permissions drop-down list box, click None.
  7. Verify that the Read check box is not selected.
  8. Click OK to save the settings.
Note Microsoft does not recommend that you use the Bin folder to store uncompelled ASPX pages. The Bin folder stores the binary files that are not included in the global assembly cache.

STATUS

This behavior is by design.

Steps to Reproduce the Behavior
