My 3-day IIS server cannot run ASP page faults

I haven't changed the webpage for a long time. I suddenly wanted to change it, but after opening the ASP page,RemoteProcedureCallFailed. After the HTTP friendly display is disabled, the Server Error 500 is displayed. the HTM page can be opened to prove that the server is running. After IIS is re-installed, the ASP page cannot be run. Later, I found an article on the Microsoft website.ArticleHttp://support.microsoft.com/default.aspx? SCID = KB; ZH-CN; 309051 "How to: Remove ASP faults in IIS 5.0. The cause of the problem may be that the IWAM user account is manually added to the guest group to the Administrator group when autocad2006 is installed.
