Hi, recently update the laptop from Home edition to Pro. After installing the IIS 5.1 service, any .asp page will be served only when the application protection in the default web site is set to low. If set it to Medium, the http 500 error page will be returned to the browser. If set it to High, an "Invalid String Class" message box will pop out within the IIS MMC snap-in. Trace the problem to the 3 missing Com+ components: IIS out-of-process, IIS In-process, and IIS utilities. Try to run "rundll32 wamreg.dll, CreateIISPackage" as suggested in Microsoft FAQ, no error message, and nothing happen (i.e., none of the components get installed). Try to run "asptxn.dll", get an "registered error" message box.
Please let me know if you may have any idea what's causing the problem, and thanks in advanced.
