w3wp

I have a Windows 7 machine (Windows version 6.1.7601 SP1 Build 7601) with IIS installed. At some point the installation appears to have become 'corrupted' in some way, as any requests are now met with the message:

Service Unavailable

HTTP Error 503. The service is unavailable.

In IIS manager IIS is started and the app pool I am using reports itself as 'Started', yet there is no w3wp.exe process listed in the process list in task manager (I am a local admin and have clicked the 'Show processes from all users' button.

I have enabled logging for the web site (at default location of %SystemDrive%\inetpub\logs\LogFiles), but this folder is empty. I am assuming that this log output is written by w3wp.exe as it handles requests (no w3wp.exe, no log file?).

Presumably there is another layer of request handling that is responsible for starting the worker processes, does thsi layer have log files I can check, and/or can I uninstall/re-install that layer?

Thanks.
