Problem

IIS returns error "405 Method Not Allowed" when posting to a CGI script

Details

IIS returns "405 Method Not Allowed" or asks you to check your MIME mappings when you try to use a CGI script such as Domain Password or Comments.

Solution

This is an IIS Server configuration error having nothing to do with MIME types. You are attempting to execute a program in a directory that doesn't have execute permissions turned on. Double-check the settings for your scripts directory. See the IIS documentation for more information.
