I have been running an Exchange 2003 Std server for the past while without any issues. This morning after rebooting my Win2003 Std server the Information store will not mount. After attempting to troubleshoot that issue, I had decided to install Exchange on another server and consider restoring my ntbackup of our mail into that one. I have installed Exchange 2003 on this new server along with the necessary SP. Now I just want to restore the mailbox backup onto the new server store and begin migrating all my client machines over to the new one. Can anyone assist to ensure that I don't screw up the new server?
