Aright, so we have a Sharepoint Services site 3.0 running on IIS 7 on a Server 2008 64 bit OS and we've had our SharePoint site up and running for about 6 months without issue until recently when I was trying to get a web component for another application up and running on the same server and IIS the SharePoint site resides on.
Anyway, while working with the support agent for the other up and running on the IIS application, one of the steps he had me try was uninstalling and reinstalling the application development portion of IIS. Since that time the SharePoint site(s) we had on the webserver are inaccessible and returning the "http 500 internal server error".
On the server itself from IIS Server manager, if I browse through our SharePoint sites by browsing in the "actions" section, I get a "HTTP Error 500.19 - Internal server error and below that, where it says "Detailed Error Information" I see:
Module: IIS WEb Core
Handler: Yet to be determined
Error Code: 0x8007000d
Config Error: Only one, <ConfigSections> element all(can't see what else it says)
Logon method: Not yet determined
Logon User: Not yet determined
And the SharePoint Central Administration page displays only a blank webpage. Any idea how I can fix these SharePoint sites? Thanks a lot for any suggestions!
