Can someone help me with the problem. When I try to access our local intranet I get a message in the browser saying 'Service Unavailable'. When going to event logs I get the following error: vent Type: Error Event Source: W3SVC Event Category: None Event ID: 1002 Date: 19/11/2008 Time: 15:20:23 User: N/A Computer: GRI Description: Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

Can anyone shed any light on this. I have been reading about to know affect. I have reviewed all permissions, disabled 3rd party services, taken off last few services. We are running Windows Server 2003 SP2 Standard 64-bit version and IIS version 6. Could there be a problem with the .NET frameworks as we have 1.1 and 2.0. Can I uninstall both and then just reinstall the 1.1. as that is what our website is run on. Many Thanks in advance.
