I have tried moving all databases to another server, but I forgot to change the default database server in Central Administration.
From Googling it, I found out that stsadm or psconfig could help me out here, but I can not figure out how to do this.
I was thinking, "What would happen if I ran the Configuration Wizard, detached from the farm, and then reattached to the existing farm?" Wouldn't that just sort it out for me?
