503 Error in Web Page

Author: Ian Britz

Symptom

When trying to access the Kepion Web Server you receive the error: HTTP Error 503. The service is unavailable.

Resolution

Password Change

A common cause for this error is that the password for the Kepion Service Identity has been changed. This is especially common if the Kepion SI is also a user account, rather than a dedicated service account. To resolve this, open IIS Manager, select Application Pools, and update the password for the Kepion Service Identity.

Security Policy Permissions

Another potential cause of this error is that the Kepion Service Identity is attempting to access the Web Server, but it doesn't have permission to Log on as a batch job in the Local Security Policy.

To configure this, open Local Security Policy:

Expand Local Policies, open User Rights Assignment, and right-click Log on as a batch job and select Properties.

Either add your Kepion SI credentials to the list below, or add them to one of the groups in the list to resolve the error.
