One of the great changes to Exchange 2010 SP1 was that a DAG static IP address can be set using the Exchange Managemetn Console. Prior to this in RTM, the Exchange Management Shell had to be used to set a static IP. An example of this would be:
Set-DatabaseAvailabilityGroup -Identity TailspinDAG1 -DatabaseAvailabilityGroupIpAddresses 192.168.2.150
In the SP1 EMC to revert the DAG to using DHCP, simply remove all the IP Addresses that were assigned.
But how can you revert a DAG back to using DHCP in EMS you may ask?
Set-DatabaseAvailabilityGroup -Identity TailspinDAG1 -DatabaseAvailabilityGroupIpAddresses 0.0.0.0
Full documentation for Set-DatabaseAvailabilityGroup is here: Set-DatabaseAvailabilityGroup.
