Endpoints And Authentication

I tried asking a similar question over at the asp.net, but I'm not getting any replies.

I created an endpoint in SS 2005 using DIGEST authentication, and I was successful in adding the web service to my project and getting results from a call to it.

However, the production environment does not exist in a domain environment, which eliminates even DIGEST (which requires a valid windows domain logon).

But, when I create the endpoint using BASIC authentication, I can no longer "find" the service. SS says the command(s) completed successfully after the Create Endpoint command. As a test, the documentation says that you can enter the http site into IE and the WSDL will display. And that works in digest mode. However, I've tried both:
http://<server>/path?WSDL and
https://<server>/path?WSDL
And neither returns the WSDL in IE (nor can it be added to my project as a web service).

I'm hoping someone has some ideas on how I can resolve this problem.

TIA,
Dave
