I have a Windows 2008 R2 Service Pack 1 server. It's virtual, not that that should make any difference. It's only purpose in life is running IIS 7 and it does that quite nicely. However, when I go to the performance monitor, there's not a choice of ASP.NET or ASP.NET applications. There is a choice of APP_POOL_WAS which has instances of the application pools I'm interested, but the counters are not very interesting. There are also a bunch of other performance counter choices. The websites use 2 application pools, each which is using v4.0 of the .NET framework. If I look in the task manager, i see two w3wp.exe's running, each a IIS worker process. I had UAC turned on, but i turned it off. I added appDomainResourceMontoring to the aspnet.config file, but that didn't help. Here's the aspnet.config file if that's the slightest help.
<?xml version="1.0" encoding="UTF-8" ?>
