Beginning yesterday morning, it seems that most of the users are being prompted to login when they launch their Outlook 2007 clients. We migrated to Exchange back in October and up until now, users would launch their Outlook clients and it would automatically open for them as long as their PCs were attached to the domain and inside our network.
I have a 2 site environment with each site having an Exchange server. Each server has all the necessary roles to function on its own. While users are fine when they enter their credentials, it is still causing us a lot of phone calls so I would love to get this fixed. I installed UR5v2 last night and rebooted the boxes to see if that would help, but it didnt.
The only thing that was done the night before this happened was a reboot of the domain contollers in each office to upgrade their VMware tools. Im guessing it has something to do with that.
Any help is greatly appreciated.
