PRB: ASP.NET 1.0 does not appear in the Web Service Extension list in IIS 6.0

When you install or register ASP.NET version 1.0 that is included with the Microsoft .NET Framework 1.0 on computer that has Internet Information Services (IIS) 6.0 installed, ASP.NET does not appear in the Web Service Extensions list in IIS 6.0. However, ASP.NET version 1.1 that is included with the .NET Framework 1.1 appears automatically.

To resolve this problem, manually add ASP.NET 1.0 to the Web Service Extensions list.

Steps to Add ASP.NET 1.0 to the Web Service Extensions List

1. Click Start, point to Settings, and then click Control Panel.
2. Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.
3. Expand Computer Name, and then click Web Service Extensions.
4. In the right pane, click Add a new Web Service Extension.
5. In the Extension name text box, type ASP.NET v1.0.3705.
6. Click Add, and then click Browse.
7. Locate Windows Directory\Microsoft.NET\Framework\v1.0.3705\Aspnet_isapi.dll.
8. Click Open, and then click OK.
9. Click to select the Set extension status to Allowed check box, and then click OK.

This behavior is by design.

When ASP.NET version 1.1 is installed on a computer that uses IIS 6.0, the installation script creates a metabase key for ASP.NET version 1.1. This metabase key allows ASP.NET version 1.1 to appear in the Web Service Extensions of IIS 6.0.

Steps to Reproduce the Behavior

1. Install the .NET Framework version 1.0.
2. Register ASP.NET version 1.0 in IIS 6.0. To do this, run the following command at a Visual Studio .NET 2002 command prompt:
   aspnet_regiis -i
3. Click Start, point to Settings, and then click Control Panel.
4. Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.
5. Expand Computer Name.
6. Click Web Service Extensions. Verify that ASP.NET v1.0.3705 does not appear in the Web Service Extensions list.
