You receive this error message if the application calls an ASP method that requires the Parent Paths option to be enabled. The exact error message depends on the method that is being called.
By default, the Parent Paths option is enabled in IIS 5.0, but it is disabled by default in IIS 6.0.
The Parent Paths option (the AspEnableParentPaths metabase property) permits you to use ".." in calls to functions such as MapPath by allowing paths that are relative to the current directory using the ..\notation. Setting this property to True may constitute a security risk because an include path can access critical or confidential files outside the root directory of the application.
If your application contains a Web page that contains the #include server-side include directive and uses ".." notation to refer to a parent directory, you will experience this issue when the application is run on IIS 6.0 with the default setting.
To resolve this problem without changing the application:
