Thanks a bunch for this. I just spent the last two hours trying to figure this out to no avail until I found this. (Would have discovered the problem sooner, but hadn’t worked on this machine since Nov 2009!)

Thanks again!

Have you tried reinstalling Service Pack 2? Though inelegant, this should fix the issue for you.

I’m still having problems related to this update. Microsoft has been totally unresponsive. Uninstalling the security update above allows IIS to run without errors but some other software we run is still crippled and either does not run or terminates related processes.

You are the man! Thank you so much! I was this close to re-installing IIS…so nice to simply uninstall that patch so that our CRM Reporting features worked again!

THANKS! I can’t believe this! I uninstalled and then reinstalled SP2 and still had issues with permissions with several processes.

This was a huge mess.

A bigger problem is that Redmond didn’t correct the issue and the update was sent down AGAIN several days later!

Thanks mate, Spent a good 4hrs on this. Would have probably taken a few days to spot this otherwise.

Thank you very much for the post. This saved me a lot of time. Here is a similar response with some additional detail:

Previous to the installation of the KB973917 update, one or more of the core IIS .dll files were not at the correct file version. Specifically, the earlier installation of Windows Server 2003 Service Pack 2 on the server did not complete successfully, leaving some of the IIS .dlls at the Service Pack 1 level while bringing others up to the Service Pack 2 level. The IIS services had been able to run successfully even with that file mismatch in place. However, the installation of the KB973917 update exposes this pre-existing file mismatch environment to the degree that IIS is now unable to function properly.

To resolve this problem, reinstall Service Pack 2 for Windows Server 2003 on the web server. This will bring all IIS 6.0 components up to the correct file versions, and will maintain the installation of the KB973917 update. Reinstalling the KB973917 update should not be necessary.
