Fixing Report Server App Pool That Won't Start

Environment

Product

Report Server

Description

I cannot start the Report Server application pool in IIS. Attempting to log in results in a 503 error stating "The Service is unavailable." The Windows log shows that the identity of the application pool is invalid, possibly due to an incorrect username/password or missing batch logon rights. Restarting the application pool leads to immediate failure.

Solution

To resolve the issue, follow these steps:

1. Verify whether the password for the ReportServerUser account has been changed since installation. If yes:

   • Open IIS Manager.
   • Navigate to Application Pools.
   • Go to Advanced Settings -> Process Model -> Identity.
   • Set the password to the new one

   

2. Ensure that the ReportServerUser account has 'Log on as a batch job' and 'Log on as a service' required user rights:

   • Open Local Security Policy.
   • Navigate to Computer Configuration -> Windows Settings -> Local Policies -> User Rights Assignment.

   

   

3. If the issue persists even after you have confirmed that the username and password are correct, troubleshoot further by generating logs:

   • Refer to Troubleshoot Report Server Manager.
   • Follow the instructions to collect the necessary logs.

Before making any changes, ensure you create a backup to prevent data loss. For detailed instructions, refer to Storage Backup - Telerik Report Server
