Service Unavailable: HTTP Error 503. The service is unavailable in SharePoint

Service Unavailable: HTTP Error 503. The service is unavailable error normally occurs whenever the password for application pool identity account is changed or application pools are in stopped state. This error may appear temporarily when you deploy solutions. In my case, I realized that password got changed for the Identity account.

Its a best practice to set "Password never expire" option for service accounts, BTW!

Here are the steps to resolve:
SharePoint Error: Service Unavailable: HTTP Error 503. The service is unavailable in SharePoint  
If you are Running SharePoint in Windows 2003:
  • Go to Start >> All Programs >> Administrative Tools >> Internet Information Services (IIS) Manager.
  • Locate your App Pool account and right-click on it and select ‘Advanced Settings’.
  • Go to process model then Identity Click on the Identity >> Set and then give the user name, password and confirm password.
Hope this will work fine after that.

Here is the Microsoft KEDB: http://support.microsoft.com/kb/823552

If you are Running SharePoint in Windows 2008:
  • Go to IIS Manager (Start > Administrative Tools > Internet Information Services Manager)
  • Expand the server node, and Click on Application Pools
  • Locate the Application Pool of the SharePoint site, If it is stopped - Start it. If the password is changed, update the password:
    • Click on "Advanced Settings" Setting Application Pool Identity in IIS
    • and then click on ... Button in Identity property
    • Set Application Pool Identity in IIS
    • Enter the User Name and password for the application Pool account.
    • Set Application Pool Account User Name password in IIS 
It could happen when the App pool's Advanced Property: Enable 32-Bit Applications is set to "True"! It should be false.

Tail: Application Pool Starting and Stopping? or Application Pools stops after restart? Make sure your application pool account has "Log on as batch job" rights!. This error may occur when necessary services like World Wide Web Publishing service, SharePoint Timer Service is in  stopped state.
