When you browse the Central admin page or SharePoint sites you may get "HTTP Error 503. The service is unavailable.

To solve check the below things...

2. In IIS, check the under sites whether Central admin page or SharePoint site manage web service stop or start. (Should be Started).
3. In IIS, and also check the under Application pools whether Central admin page or SharePoint site task services status. (Should be Started).
