You will first need to do additional troubleshooting to figure out what IIS is doing at the point that it crashes.

What can you tell us about the web site? Does it serve up ASP, ASPX, PHP pages? Or something else? Was this code developed by someone in your organization or did you install some 3rd party software that is hosted by IIS?

Does it crash immediately, or does it successfully serve up pages for a while and then it crashes? Has it always crashed, or did you recently install something and this problem started after that?

Check the logs in C:\Windows\System32\LogFiles\HTTPERR to see if it identifies the URL being processed when the crash occurs. Check the application and system event logs to see if any additional diagnostic information is available.

Two common IIS problems are hanging requests and memory leaks.

Launch the IIS manager and from the home tab double click on Worker processes. Make note of the Private and Virtual bytes reported. Monitor those over time and see if the values continue to increase. Right click on the app pool and select View Current Requests. Look at the Time Elapsed value and see if you have requests that are running for a long time.
