In this post we will discuss how to resolve SharePoint 2013 error HTTP Error 503. The service is unavailable which appears while opening SharePoint 2013 Central Administration. Also check out:
Recently some windows and SharePoint 2013 updates happened in my laptop. After that when I restart my machine and try to open SharePoint 2013 Central Administration, I got the below error:
HTTP Error 503. The service is unavailable.
If the above error comes then you can check below things:
- If you have changed the password recently, then you may got this error. Follow this article
to resolve the issue.
- Next thing is you can check whether some services like SharePoint Administration, SQL Server (MSSQLSERVER) are running or not. Go to run and write services.msc and click on OK. This will open the services screen. There you can check whether SharePoint Administration, SQL Server (MSSQLSERVER) are running or not. If those are not running then you can right click on the particular service and click on Start.
- But the problem I found in my case is that, SharePoint Central Administration Application Pool has been stopped like below:
To start go to Run -> inetmgr. This will open the IIS. There click on Application Pools from the left side. This will open all the application pools. Select the application pool, Right Click -> Start.
Now you should not get the error.
