Q6920010: I'm monitoring my IIS Application Pools using ActiveXperts, but on one server I receive the error "WMI Error 0x8004100E: The specified namespace did not exist on the server.". What's wrong?
First of all, make sure that other WMI based checks on that server do work fine. For instance, try to monitor the CPU usage on that server using the ActiveXpert CPU check.
Then, make sure that you have installed the 'IIS Management Scripts and Tools' component of the 'Web Server' role. The 'IIS Management Scripts and Tools' component is NOT installed by default!
To do so, start the 'Server Manager' tool of Windows, select the 'Dashboard' tab, and choose 'Add roles and features'. Configure the 'Web Server' role to include the 'IIS Management Scripts and Tools' component.
