I am running Exchange 2010 SP1 with all the roles on a single server. We had been operating in a mixed mode during our transition to Exchange 2010 at the end of last year. After the competition of the transition, everything had been running smoothly.
Recently, we have decided to add a Mailbox server, to house our archive mailboxes.
When running through the installer, it fails. It references that it cannot find the legacy GWART.
I have went back and inspected our configuration. I can’t find any lingering 2K3 items… but I suspect my system still believes they should be there.
