I have a client that I installed a SBS 2008 who is using Outlook 2007 back in the middle of November. This week he is being asked for his credentials to logon to the remote.domainname.com. No matter what combo of username we try, the pop will not go away. He is connected to Exchange and recieving mail just fine. Its just becoming annoying. I re-ran the Setup interenet address and Certificate wizards and it still is a problem. I do know the server did Windows updates over the weekend as well.
