I boyz, I've a Windows 7 64 bit pc, with WSS 3.0 installed and VS2008 extensions for WSS v1.3. I create a Sharepoint Webpart project and it has been creately right. It builds right too. But when I try to debug it, or to create a deploy / package, I obtain this error: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Basic realm="127.0.0.1"'. How can I resolve it? Thanks.

Have you configured NTLM Authentication in IIS, please check the same. -Mukesh
