Did anyone ever get an answer for this? The initial response, marked as "answer", worked for a while, but now has stopped working, and I'm desperate! Any thoughts?

I am also running into issues with web service binding and 401 Unauthorized errors when using ServerSide Resource Population.

My current development environment is set up to use a local instance of full IIS on my Windows 7 machine (not IIS Express). I have enabled at the site root both anonymous access configured with IUSR as well as Windows Authentication to enable debugging. We do use cookies for authentication but do not integrate with ASP.NET authentication and failure to authenticate in code does not return a 401, but rather a redirect to another page. Based on this, I'm sure the issue is not our websites cookiebased authentication but rather having enabled Windows Authentication and somehow it fails as this will definitely cause a 401.

Any advice on how I may pass through my current credentials?

Hi Nelson,

 
We are not aware and have not been reported of another known settings that may be causing such error out of the box so it may be caused by some custom setting. If you are still observing the issue please if you find out more information  about it.
