I'm looking for information about license needed for a DAG with 2 node.
I have 2 Exchnage 2010 enterprise on 2 Windows 2008 R2 Enterprise. I need create a DAG between the two server.
I have anothe Windows 2008 R2 server standard. I need also a third license of exchange for installing HUB on the Witness server?
In my forest I don't have the "Excnage Trusted Subsystem" group. How I can add this group?
