Help required on Digest Authentication !!

Hi,

Web Server: IIS 6.0
OS: Windows Server 2003
Client: VB 6.0 with SOAP tool kit

We need to setup "Digest Authentication" for a Web Service which is hosted
on a IIS Web Server. A VB 6.0 client connects to the Web Service using SOAP
tool kit.
We have enabled the Digest Authentication in the Web Server.

According to the SOAP tool kit user help, the following is prescribed for
Digest Authentication.
Connector.Property("WinHTTPAuthScheme") = 8

With the above code when the client tries to connect to the web service, it
is giving the following error message. " "No matching authorization scheme
enable on connector".  But, with the same authentication in the web server
if we connect to the web service from IE client, it is working fine.

At the same time when we change the Authentication mode to "Basic" in the
web server and change the VB 6.0 code as below then it is working fine.
Connector.Property("WinHTTPAuthScheme") = 1

We want to know how this could be resolved so that the VB 6.0 client could
connect to the  web service with "Digest" authentication.
Any pointers  on this will be appreciated.
