IIS 7.5 site can't authenticate itself

Question

I have a couple of sites on the same server and same domain (site1.domain.com, site2.domain.com...) which talk to each other with http post request. This works fine, but I also have a dev version of all sites that is under basic authentication so you need a username/password to see the sites, and on these the http post request doesn't work.

This seems to be because the server can't authenticate itself which seems kinda weird to me, I don't have much experience with IIS thou so probably have missed something.

Anyone know how to solve this? Don't know if it makes a difference, but the sites are using php, not asp.net

You will need to send your credentials with your request. I do not know much about drupal_http_request, but if it doesnt have built in methods to add credentials to the request, you can manually add an auth header by base64 encoding your credentials.
