While working on the development path you would come to a point where some maintenance is required. You have to fix some issues in the service pack or you are unable to proceed without a language pack. Taking these issues into account you have installed a language pack that was already installed. The installation of the language pack fails and it gives an error message in that particular language. Now you would find the error 503 in the website, in Central Administration. This error can be fixed by following some manual steps.

Symptoms of http error 503

You have to check your windows log event, ULS log event, IISRESET, IIS Manager and your web application one by one, and see that if they are working or not. If you find that only the web application is running then that means that the application pool has stopped as well as the installation process.

Steps to fix http error 503

You have to go to the Internet Information Server (IIS) manager and select the Application Pool you may finds that Share Point Application has stopped working. This includes web applications, central web services such as STS and central administration. To fix the problem you have to select them and right click and select start; the Application Pool would start running. If it do not start then check that the permissions or users have not changed, to change them go to Advanced settings (by right clicking them) and update it with the help of Set button. You also have to make sure that if the web application started with 32 bit ASP.NET application, and by some means got converted or upgraded to SharePoint 2010 web application. In this case you would find that the application pool has the “Enable 32-bit Application” is set as true, which is not compatible with SharePoint. You have to set this property to false and the problem would be solved. If after performing these steps the problem still exits, then with the help of SharePoint server Repair tool this issue can be fixed. This software scans the damaged database files and repairs it and recovers the inaccessible objects. It allows the user to retrieve all database of the share point. It restores deleted or corrupt database and save them on the system.
