Redgate ANTS Performance Profiler - Could not start IIS.

I have had this issue a few times and I always forget how to fix it.

So I need to run my IIS as a network user in order for it to work through SQL Auth etc, the reason it is failing, is because the user isn't an admin user on my box. So go to Administrator Tools -> Groups -> Administrators and add your network user here, check names and it should work!
