As a last resort, you can re-create the IIS packages. To do this, follow these steps:
Browse to Component Services and delete the following packages:NOTE: To delete the packages, you must first open the properties of the package, click the Advanced tab, and then click to clear the Disable Deletion check box.


IIS In-Process Applications
IIS Out-of-Process Pooled Applications
IIS Utilities
Open a command prompt, and then use the following command to switch directories:
cd %windir%system32inetsrv

Run the following commands:
rundll32 wamreg.dll, CreateIISPackage

NOTE: "CreateIISPackage" must be typed exactly; it is case-sensitive.
regsvr32 asptxn.dll

Close and reopen Component Services. You should see all three IIS COM+ applications that have been recreated.
Run IISRESET from a command line and test any ASP page that previously did not load correctly.
