SBS 2003 Remote Access

Hello all. I do need some help.
I need to remotely access an SBS2003. It’s running SP1. When I type in the address for the server, it comes up with a login screen (user name, password) instead of showing the regular “Welcome to Small Business Server 2003” screen. It seems that no matter what I try, it will not get there. I have made sure that permissions have been given, services are running, etc. and still nothing is working.
Has anyone had a problem with this same issue before? What am I missing?
Thanks!
