SharePoint App Pool Identity Problem

​If you see this error and you Central Admin and intranet are not workign and showing as stopped in IIS:

The identity of application pool SharePoint – 80 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.

 

Application pool SharePoint – 80 has been disabled. Windows Process Activation Service (WAS) did not create a worker process to serve the application pool because the application pool identity is invalid.

  2. Beneath Security Settings, open Local Policies and highlight User Rights Assignment.
  3. Locate Log on as a batch job. Open the properties and add any users that need this right.
