If you are using Windows Server 2003 IAS with a third-party access server, you might need to configure the IAS server to prevent it from sending the class attribute. Specifically, if the IAS server sends the class attribute, some network access servers require the use of certain vendor-specific attributes to be included in the class attribute.

Alternatively, you can configure vendor-specific attributes and custom attributes to enable compatibility with a third-party access server.

For more information about how to configure the class attribute, see "Add RADIUS attributes to a remote access policy" in Help and Support Center for Windows Server 2003.
