From: Big Daddy on 6 Aug 2010 11:50 When I open a web browser pointing to anything in this web server, the web page just says: "Service unavailable". The OS is Windows 2003 SP2. Even if there's a simple html page in the root IIS folder, it can't display it. I have looked around the internet and tried a few different things: - Many people suggest that I can change the IIS configuration to use IIS 5.0 Isolation Mode. This works for me, but I don't want to switch to IIS 5.0 Isolation Mode. I think IIS should be able to work without this. - Some people suggest that some of the files for Windows Server Service Pack 2 might not be installed correctly. So I ran a script suggested at this link: http://blogs.msdn.com/b/webtopics/archive/2009/12/18/sample-script-to-verify-iis-file-versions-for-kb973917.aspx?wa=wsignin1.0 But that wasn't the problem since all my files are up-to-date. - I looked in the event log and couldn't find any error messages relating to IIS. It doesn't seem like IIS is writing logs to the C: \WINDOWS\system32\LogFiles\W3SVC1 folder even though logging is enabled. Any ideas? thanks in advance, John
From: Ken Schaefer on 9 Aug 2010 07:49 Hi, 503 Service Unavailable is returned by http.sys - it has it's own log (httperr.log). Check in there to see if that gives you any clues. also, look again in the Windows Event Log (not the IIS one). Just in case IIS is crashing - there will be events logged, If IIS services can't start at all, the events will be logged when the machine is started, not when you are trying to access the webpages.

The entries in it said "Disabled DefaultAppPool". For some reason the DefaultAppPool was not started, and starting it fixed the issue. thanks a ton!
