I have two different domains running on Windows 2003 server. While trying to access one of the servers from the other domain, I am able to simply go to Start->Run and type in \\server and the shares pop up with no authentication! This is driving me crazy because I have secured down the server in every way possible as far as security permissions and share permissions. I'm very confused about how I am able to just path right to the server without being asked to authenticate. Every other server that I path to on the domain asks for a username/password. Please help, any advice is a appreciated.
