The Problem
You are working away, using the wonderful dotless plugin for IIS, and also taking advantage of the great features of the Less Css System. Then, for no good reason, your .less file stops loading. You create all sorts of new Mime types and reboot the server, but nothing seems to work, how do you fix it?
The Cause
Upon closer examination, you uncover the following error
HTTP Error 500.21 – Internal Server Error
Handler “dotless” has a bad module “ManagedPipelineHandler” in its module list
even though you have not changed anything about dotless.
The Solution
At some point the application pool has changed. Just change it back to a more recent version (I was using a custom application pool) and the problem goes away.

This I snot a solution. It’s a hack that happened to work for you but will probably not work for anyone else. Shame on you.
It is a minor solution to a minor problem. Most people will not get the problem in the first place.
Yes, not a solution for me either.
My IIS app pool changed as well – thanks for pointing it out but the solution itself is not sufficient.
