SCOM 2012 SP1 client-side event 34215

This is a short tip to solve the error event 34215, this event appears when client-side is trying to write an extra configuration into a IIS shared configuration and you don´t have enough permissions.

First thing, is understand how client-side monitoring is deployed. By default, client-side monitoring, tries to create the CSMCollector virtual directory and the OperationsManagerCsmCollector v.4.0 application pool when you execute the client-side wizard in the SCOM console.
The solution is easy, just give the computer permissions (web server) over the shared directory of IIS config.

After that you will get an event 34243 that means "The new client-side monitoring configuration has been successfully applied. No conflicts were detected."
