So first the background:
Corporate network, two sites connected via MPLS.
Site A has 2 x 2008 R2 DC's and 1 x Exch 2010
Site B has 1 x 2008 R2 DC and 1 x Exch 2010
Site B was the second Exch server to go live, which was completed roughly two weeks ago. Since then many... many of the users here at Site B get prompted multiple times throughout the day to authenticate in Outlook, it always defaults to *email-server/username* versus *domain/username* which I still can't figure out. Anyway about half the time getting the user to manually type in *domain/username* solves the problem, they connect and work just fine for a few days or so until it happens again.
A third of the time the user has changed their domain password that same day and had not closed Outlook or rebooted their pc. So a reboot is the easiest and usually what I make them do and afterwards Outlook is just fine.
*EDIT* I've discovered that some
of these users so far have Outlook clients that are still trying to access Public Folders on servers that have been shut down. Around a month ago I followed the steps outlined here: Moving PF from 2003 to 2010
And gave each of the two old Exch 2003 servers a week to replicate before shutting them down.
But I've had a very hard time trying to find out why this whole Outlook/Exchange/domain controller disconnect happens in the first place.
Did we potentially miss an option or mis-configure something server side? Anyone know why this would happen so often?
