Unable to add CrmDeploymentService Web Reference due to Authentication Issue

Question

I am having an issue adding a Web Service Reference to the CRM Deployment Service at http:///MSCRMServices/2007/CrmDeploymentService.asmx

When I first attempt to connect it says Connecting to and prompts for credentials. After entering my credentials, it will continue to prompting for credentials indefinately.

When I attempt to navigate to the service in IE, I get prompted for credentials and after submitting them a few times, I get a 401 error.

When I attempt to navigate to the service in Firefox or Opera, the basic authentication dialog pops up and I enter credentials. The service description page correctly appears.

Is there something preventing IE/VS from submitting the credentials correctly? In each place, I am using the same domain/user credentials. I have tried it from IE on both a computer on the domain and a computer not on the domain and get the same results.

Not sure if this will help, but I vaguely remember something like this happening to us at work, and someone fixed it by disabling IPV6. Like I said my memory is hazy so I don't know if this is the exact problem that we were having too. I just remember that the solution was to disable IPV6 on the server.
