I'm running into an identical issue as Mr. Trex has described but it only seems to happen on Windows 7 machines joined to my domain. Windows 7 off the domain doesn't prompt for password and Windows XP on or off the domain don't prompt either. Any thoughts
on why the combo of Windows 7 + Domain are resulting in "The first HTTP CONNECT request is done with UserAgent: Microsoft-WebDAV-MiniRedir/6.0.6001, and results in a logon prompt." ?
