HTTP Error 503. The service is unavailable in SharePoint

In this post we will discuss how we can resolve the issue which usually comes in SharePoint. The error message is: "HTTP Error 503. The service is unavailable in SharePoint".

Also you can check out my previous posts on:

- Difference between Apps and Solutions in SharePoint 2013

- Apply html to email template in SharePoint 2010 designer workflow

- New actions in SharePoint designer 2013 workflow: Call Web Service Action and Start workflow action

The full error message is: "HTTP Error 503. The service is unavailable in SharePoint".

This error normally comes whenever a user changed the password for the account.

To correct the error follow the below steps:

Go to Start -> All Programs -> Administrative Tools -> Internet Information Services (IIS) Manager.

Then Click on(+) the server name -> Application Pools then locate your application pools. Right click on the Application pool name go to Advance settings.

Go to process model then Identity Click on the Identity ->Set and then give the user name, password and confirm password.

This solution works for me, Hope this will also solve your problem.
