Hi, having a problem with Application pool plesk 12.5 newly installed on a windows 2012R2 installation.

Tried all the articles to fix is but if i start the application pool and try to access the panel the pool gets disabled again.

Tried the following solutions:

https://kb.plesk.com/en/120704
https://kb.plesk.com/en/6735

Password changed for the psaadm.
Run the repair tool to fix services

Nothing seems to work.

In the server manager i get these warning
The identity of application pool PleskControlPanel is invalid. The user name or password that is specified for the identity may be incorrect, or the user may not have batch logon rights. If the identity is not corrected, the application pool will be disabled when the application pool receives its first request. If batch logon rights are causing the problem, the identity in the IIS configuration store must be changed after rights have been granted before Windows Process Activation Service (WAS) can retry the logon. If the identity remains invalid after the first request for the application pool is processed, the application pool will be disabled. The data field contains the error number.

and Error
Application pool PleskControlPanel has been disabled. Windows Process Activation Service (WAS) encountered a failure when it started a worker process to serve the application pool.
