I have a user that is having a problem logging onto OWA on a Exchange 2000 Server. They enter the address of OWA and the logon screen comes up asking for the username, password, and domain. The user enters the information and you see the OWA screen start to display and then it stops and the authentication screen comes up again. The inforamtion gets entered again and the authentication screen comes up again and again. If you hit the cancel screen on the authentication screen after you have authenticated once, the authentication screen goes away and the user gets the error message that access is denied. If you click on the address field, hilighting the OWA address, and hit Enter OWA opens properly without asking for the user credentials again. Any ideas why this is happening.
