I've been using the following WMI query to check how many IIS sites are currently running on my Windows 2008 webservers:

SELECT ApplicationsRunning FROM Win32_PerfRawData_ASPNET4030319_ASPNETv4030319

After replacing these webservers with 2012 equivalents, this query always returns 0, even though my sites run ASP.Net 4.

Does anyone know why this happens, and how to fix it ?

I found this KB article: http://support.microsoft.com/kb/2869514

After installing .NET 4.5 you are not able to access performance data using WMI. For example, when you try to get the value for the Win32_PerfFormattedData_ASPNET_ASPNETApplications performance counter, the value returned using WMI is always 0.

This is by design as a security fix. Only admin and performance log/monitor can access asp.net performance information.

Unfortunately I haven't yet found a way to make it work.

  • Sorry about the late reply, this does sound like the cause - I'll try using an admin account and see if that solves it :-) – Steffen Jun 08 '14 at 13:31
