Service Unavailable – HTTP Error 503. The service is unavailable.
I found a post from Rich Strahl that pointed me in the right direction. When I brought up my Internet Information Services Manager and clicked on Application Pools, my DefaultAppPool was stopped.
Unfortunately, my application pools were already set to auto-start and restarting the application pool didn’t solve my problem. As soon as I tried to bring up my website, the application pool would immediately stop again and give me the same error screen. After spending the next 10 minutes or so restarting Windows 7 and starting and re-staring my application pools to no avail, I decided to re-install my IIS7 and Windows Process Activation Service features.
After re-installing these windows features, everything was back in order. Unfortunately, I did have to add ALL of my virtual directories again, but I expected as much. You can re-install these features from the Programs and Features screen by clicking on Turn Windows features on or off.
On the Windows Features screen, you can uninstall any feature by removing the check next to it and then clicking OK. You can then return to this screen after restarting windows to reinstall them.
Hope this helps someone. If anyone knows how to correct this without reinstalling the features, please comment!

Hey man, I have this same error and I did exactly what you did and it still doesn't work. I can't find anything on the internet that points me to the right directionm what fo you think could it be?
If uninstalling and reinstalling IIS7 and Windows Process Activation Service didn't fix the problem for you, I'm not sure what else could be causing it.
It might be something specific to the web application or virtual directory that you have running on the application pool. You might want to create a new application pool to test with to rule out issues with just the Default pool.
Sorry, I wish I could be of more help.
Just had the same problem with IIS 7.5 on Windows 7.
The DefaultAppPool was stopped and when I started it again it still didn't work.
Looks like the DefaultAppPool is damaged somehow. I created a new new AppPool based on the settings of the DefaultAppPool, selected this AppPool in the Default Web Site basic settings and everything is up and running again.
It is not a solution in my opinion, but it is at least a good work arround.

STOPEDED for some time only? This is definitely not the ACQURATE solution
After starting Default Application pool it worked fine for me :)
