I have an intranet server on a Windows domain (server is Windows 2003, IIS6, NTFS permissions). It is on the domain Domain01. I have users from two domains in the same forest that access this intranet: Domain01 and Domain02 (DCs also running Windows 2003). Currently, the users are required to login by entering either: Domain01\username or username@Domain01
My users are completely and thoroughly confused by having to enter the domain each time they log in. Is there any way to simply allow them to log in by entering just their username and password WITHOUT the domain? For example, have the server try Domain01 by default, and if the login fails to try Domain02?
NOTE: I would like to do this via IIS or server settings if possible, rather than programmatically (for reference, I am using ASP.NET 2.0).
