I am running Exchange 2003 for a mail server, and Windows Small Business Server 2003 as my NOS.
When users attempt to open Outlook and gain access to their mailbox, the system is prompting them for a username/password. Even when the correct credentials are entered, the box just prompts them again, and again...
This has started to happen on Friday morning and has reoccurred everyday since. It seems to affect about 5 people in a group of 12.
All other network services are up and running fine and only Outlook is problematic. There has been no other changes to the network.
A work-around is to get the user to restart their machine though it can take several attempts for the prompts to stop appearing.
I have no clue where I should go from here... any help is greatly appreciated.
