One application pool on one of our webservers crashed and we found this in the Eventlog, where can we find more information about it?

Event Type: Error
Event Source:   W3SVC
Event Category: None
Event ID:   1101
Date:   	11/23/2009
Time:   	10:57:55 AM
User:   	N/A
Computer:   ID-WEB
Description:
The World Wide Web Publishing Service failed to create app pool 'Global'.  The data field contains the error number.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Attempting to manually start the application pool gives the following in the event log:

Event Type: Error

We are running IIS 6.0 on a Windows server 2003 R2, 32bits.

Unfortunately the events for application pool crashes in the event log do not give much information. Your going to want to run a tool such as IIS Debug, which will run on your server and wait for a crash to happen and log debug information about what occured.

App Pool crashes are usually because the AppPool Identity isn't a member of the IIS_WPG local security group... Additionally, the AppPool identity must have read access to the web content that is being displayed...
