I receive HTTP error 405 - why?

Created 2001-07-10 by Rainer Gerhards.

Question:

When trying to run PasswordManager on NT Server with IIS I'm getting the following message

HTTP Error 405 405 Method Not Allowed

The method specified in the Request Line is not allowed for the resource identified by the request. Please ensure that you have the proper MIME type set up for the resource you are requesting.

Please contact the server's administrator if this problem persists.

Any ideas how to resolve this?

Answer from Adiscon: PasswordManager is a high performance ISAPI DLL. As such, it is an executable from the web servers point of view. By default, there are no execute rights granted to any web component. This must be made manually.

Please don't mistake the NTFS execute permission with the web execute permission. While the NTFS right is needed (and turned on by default), the IIS right is set in the Internet service manager (or correspondig MMC under Windows 2000). This setting is found on the "Home Directory" or "Virtual Directory" property page. Please look at the "Execute Permisions" setting. By default, it is set to "Scripts only". For PasswordManager to work, it needs to be set to "Scripts and Executables".

Here is a sample screenshot from IIS manager. Please note the red encircled area:
