Identifying IIS Worker Process in Exchange 2013/2016

It might come a time when troubleshooting performance issues where we need to identify exactly what a particular IIS Worker Process is in an Exchange 2013 environment:

First thing we need to do is get the Process ID (or PID). To do this, right-click on one of the columns and select PID:

We can now see that that PID for the IIS Worker Process we are trying to identify is 10300:

Now open a Command line or PowerShell console, navigate to Windows\System32\Inetsrv and then run the command “appcmd list wp” or “.\appcmd list wp” if you are using PowerShell:

We now know that the IIS Worker Process with the PID of 10300 is the Exchange OWA Application Pool.
