Answer 1

It's a registry permission issue. This should help: http://support.microsoft.com/kb/885654

You might also need to add read/write permissions for NT AUTHORITY\NETWORK SERVICE (or NT AUTHORITY\SYSTEM or the account used by your application pool) to c:\Windows\TEMP. See http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/176e9b6d-7b1b-4667-b55e-330bec133f37/

Answer 2

IIS comes with a feature called Rapid-Fail Protection. By default an App Pool is configured to become disabled if a worker in the pool crashes 5 times within a 5 minute span.

The thresholds of this setting are able to be modified by right clicking on the App Pool going to Advanced Settings and modifying the 'Rapid-Fail Protection' properties. However, this event indicates that there is likely a serious issue in your application that needs to be resolved.
