Registering IIS with ASP.Net

Here's a command I have trouble remembering, but find myself needing on a few occasions. If you ever need to register or re-register ASP.Net on IIS, use this command:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis -r

You'll know you need to do this if you've installed the .Net Framework and IIS complains that it doesn't know what the heck to do with all those aspx pages.
