SharePoint: Service Unavailable with 503 error

I was working on a POC and all of the sudden my SharePoint site and Central Admin started giving me the error ‘Service Unavailable HTTP Error 503. The service is unavailable’ and I was not able to access either of them.

I realized that I had changed the password to the Identity account password (20 days ago) and just recycled the app pool now. Then this started happening. So I did the below to get the sites up and running after giving lots of scratch to my head.

  1. Open up IIS Manager and click on Application Pools.
  2. Locate your Application Pool for which the Account password reset happened and right-click on it and select ‘Advanced Settings’.
  3. Click on the right of the Identity box to change it (A window will pop up).
  4. Click on Set and simply retype your App Pool Identity in there with the new password.

How weird it is but unfortunately this is how it works.

Microsoft should take care of thread Identities in the future releases…. 🙂
