With my next script you could export and then compare almost all Exchange 2010 server settings between different servers in your exchange org – considered are HUB, CAS, Mailbox Server Roles and DAG. Script exports all Exchange Server settings in single file per server. Then you can use for example windiff tool to compare files and see if you have deferent setting on different server. I will try to update my script later to automatically compare settings.
