I have sbs 2003 up and running well. RWW works fine, except that once logged into RWW, if the user selects either OWA or the Company Web Site, a second login (windows dialog box) is required.
My account with administrator privileges does not do this. I log in to RWW and everything works without further logins.
I've run the wizards multiple times, and I created the users based on the User template which is supposed to have access to RWW and OWA.
