OWA continually asks for user login details on certain users


I have a windows 2000 SBS server , when one of my users attempts to log onto OWA, they are continually prompted for their log on details, even though we know the username/password is correct.

If they try to log on with thier user name and then try to log on using administrator, the users mailbox appears but loads the page slowly

is anybody able to offer suggestions

many thanks

It sounds like there is a combination of IIS problems, as well as NTFS permissions that are causing this.  Use this article to correct your NTFS permissions.


If that still doesnt clear up the issue then the IIS virtual directories probably need to be recreated.  The process for which can be found here.
