Recently I found myself trying to load an old .NET 1.1 application onto a virtual machine that I had just set up. I ran into problems getting the application to load. This was because I had installed MS Server 2003 as the operating system on my virtual machine. Server 2003 comes with IIS 6.0 and is set up for .NET 2.0 applications. 

The .NET 1.1 framework is disabled in IIS 6.0 by default. Because who needs .NET 1.1 anymore, right? Well I did... And you may be surprised at how many legacy .NET 1.1 apps are still out there.

It turns out that it is fairly simple to get .NET 1.1 working with IIS 6. You can enable this either by using the Configure Your Server wizard or you can manually enable it through Add or Remove Programs in the Control Panel. This article deals with manually getting the .NET 1.1 framework working with IIS 6.

	First open up the Control Panel and click on Add or Remove Windows Programs. The choose Add/Remove Windows Components.
	In the Windows Components Wizard, choose Application Server then click the "Details" button. This will open the Application Server window.
	In the Application Server window, ASP.NET should be unchecked. Check it and click the "OK" button. The Application Server window will close. You should be back at the Window Components Wizard window. Click the "Next" button.
	Wait for the .NET 1.1 framework to be enabled. Click the "Finish" button on the Windows Component wizard to finish the task.
	Now .NET 1.1 is enabled and should show up in the IIS MMC

Now, with the .NET 1.1 framework working, you can work on .NET 1.1 applications.
