Consider the following scenario. You run the IIS Lockdown Tool in Express mode on a computer that is running Microsoft Internet Information Services (IIS) 5.0. Then, you try to browse .asp pages on a Web site. In this scenario, the .asp pages are not displayed as expected in the Web browser. Instead, you receive one of the following error messages:

This issue occurs when the IIS Lockdown Tool maps the .asp file name extension to the 404.dll file.

To resolve this issue, map the .asp file name extension to the Asp.dll file. To do this, follow these steps:

1. Click Start, click Run, type inetmgr in the Open box, and then click OK.
2. Expand ComputerName, right-click the Web site that you want to configure, and then click Properties. For example, right-click Default Web Site.
3. Click the Home Directory tab, and then click Configuration under Application settings. The Application Configuration dialog box appears.
4. Click the Mappings tab.
5. In the Extension column, click .asp, and then click Edit. The Add/Edit Application Extension Mapping dialog box appears.
6. In the Executable box, type the following line, and then click OK:
   Drive: \Windir\System32\Inetsrv\Asp.dll
   Note Windir is the name of the folder that contains the Microsoft Windows system files. For example, if Windows is installed in the Windows folder on drive C, type the following line:
   C:\Windows\System32\Inetsrv\Asp.dll
7. Click OK two times.
