ASP.NET v4.0 Application Pools Don’t Show Up in IIS

On a Windows Server 2008 R2 Machine, a default operating system installation was performed along with installing all of the Windows Updates to include the .NET Framework v4.0, then IIS was installed. On this particular server, the ASP.NET v4.0 Application Pools didn’t show up automatically in IIS:

iis-net4-app-pool1

My guess is this is because the .NET Framework 4.0 was installed before IIS. To resolve this issue open a command prompt as administrator (elevated privileges if UAC is enabled), change into the .NET Framework 4.0 directory and run”aspnet_regiis.exe -ir“:

iis-net4-app-pool2

Refresh IIS and the ASP.NET v4.0 Application Pools should show up:

iis-net4-app-pool3
