Exchange 2010 site swicth over
I have a 2010 exchange DAG with DAC enabled. It is spread across two remote sites single AD forest with two AD servers in one site and two in the other. the configuration is 3 mailbox servers and one witness server in site 1 and 2 mailbox servers with an alternate witness server in site 2. I am trying to wrap my head around the votes in this configuration to keep site 2 up,
if I am correct in thinking?
In site1 3+1 =4 votes in site2 2+1=3 votes if I lost site one completely would site 2 crash completely because of to many votes are lost?

ASKER
members in site 2 are in the same DAG they also hold 1 active database each and 1 passive copy of the other 4 databases
ASKER
as for the witness servers I should just remove the primary one in site one and make the one in site 2 primary witness?

so Simon you are saying if I open EMC and navigate to organization configuration and look in database availability groups I should see DAG1 and DAG2? currently I see DAG1 with 2 DAG networks

Simon I have attached a picture of what I see can you explain to me what is wrong, then I will contact MS support and get this configured right. I knew something was not right!@

I am currently engaged with MS support, and they are running me thru the ringer as usual
Are members in Site 2 in the same DAG? Are they configured as Passive, Lagged Copies? I assume all the active copies of databases are in Site 1?
