Cause

DefaultAppPool is stopped.

Resolution

Start the DefaultAppPool.

Launch IIS manager

• Start > Administrative Tools > Internet Information Services (IIS) Manager

 

• In IIS Manager:
  • on left-side:
    • IIS > (local computer) > Application Pools > DefaultAppPool.

check the dot in the lower-left corner of the DefaultAppPool icon

• if the dot is green the pool has been started
• if the dot is red the pool is stopped.

If the pool is stopped, then

• on left-side:
  • right-click on DefaultAppPool
  • Select: start

Now, the dot on the icon should change to green. Wait a few seconds, and make sure the dot remains green.

Note: If the application pool does not stay running,then there is something more going.
