This question is related to: Windows authentication does not work
I am developing a .NET 4.0 MVC3 application that has Integrated Windows Authentication turned on. If I open my application from my development machine (I am logged in as DOMAIN\USER) I am logged in automatically as DOMAIN\SERVERADMINACCOUNT. From any other machine on the network everything works as expected (current user is logged in automatically using NTLM).
Does anyone have an idea what's happening? The server is Windows 2003 with IIS6. All clients machines are Windows XP with SP3 or Windows 7 (mine is XP).
