Bad or Missing Channel File URL When Multicast & View ASX Link

Last reviewed: September 16, 1997

The information in this article applies to:

  - Microsoft NetShow version 2.0

SYMPTOMS

When you try to multicast and view an ASX link, you get an error message that there is a bad or missing channel file URL.

CAUSE

The above problem is most often caused by an invalid path for the channel file URL when you create the channel.

If you are using a proxy server that requires authentication, you will get the above error message. This is because the HTTP browser can authenticate with the proxy by the NetShow control. However, it cannot use either Basic or Microsoft Windows NT Challenge Response authentication.

WORKAROUND

Check that the path listed in the channel is the proper path to the channel file (.NSC file) and re-export the channel file.

You must also ensure that when you host the NSC file from a file server, that the user also has access to this file. If this file is being hosted from an HTTP server, you must allow anonymous access to this file.

You can test the server for anonymous access by using the client to open an HTTP location to an ASX file. If this is successful, make sure the NSC file is also allowing anonymous access by disabling the other authentication methods or checking the HTTP server log files.

MORE INFORMATION

Below are some quick notes on anonymous user access on an IIS webserver:

In the Microsoft Internet Service Manager, open the WWW Service Properties.
Verify the Anonymous Logon Username and Password.
Verify the username and password in the WWW Service Properties has an identical username and password used in User Manager.
Run User Manager to verify the local logon rights for your designated anonymous user.
-or-
Run the Microsoft Internet Service Manager to change your anonymous logon user to an account that does have local logon rights. Verify the same username and password as used in User Manager.
