Checking IIS 7 Event Logs

One of the simplest ways to troubleshoot IIS issues is to check the event logs. This can be done by running the Event Viewer. Click the Windows Start button, type "eventvwr" and press enter. Or if this is too hard to remember, simply type event and the Event Viewer should show under Programs in the search results.

The Event Viewer can easily be found by typing 'event' in the search box after clicking the Windows Start button

Go to Windows Logs -> System and on the right panel look for events from WAS.

You can also create a custom view to only find the WAS events. Right click on Custom Views -> Create Custom View -> Click the "By source" radio, select WAS as "Event Source" and click OK.
