WAS event error

Hi

I have created a new domain with 2 domain controllers 2008R2
Then created a 2008R2 server(running on VMware), where i installed Exchange 2013, and after that installed CU1, also applied all windows updates available.

My problem is in Event Viewer System, I get this error several times each hour.
The Windows Process Activation Service failed to generate an application pool config file for application pool 'MSExchangeRpcProxyAppPool'. The error type is '7'. To resolve this issue, please ensure that the applicationhost.config file is correct and recommit the last configuration changes made. The data field contains the error number.

The application pool, changes between these:
MSExchangeRpcProxyAppPool
MSExchangeOABAppPool
MSExchangeECPAppPool
MSExchangeServicesAppPool
MSExchangeOWACalendarAppPool
MSExchangeOWAAppPool
MSExchangeAutodiscoverAppPool
MSExchangeRpcProxyAppPool

I also get this once a hour.
The Microsoft Exchange Transport service terminated unexpectedly.  It has done this 1 time(s).  The following corrective action will be taken in 5000 milliseconds: Restart the service.

Then this:
The Service Control Manager tried to take a corrective action (Restart the service) after the unexpected termination of the Microsoft Exchange Transport service, but this action failed with the following error: 
An instance of the service is already running.

Hope someone can help
