Does it make sense to place DAG members in different sites when the witness server must stay in one of them? Think to this configuration: two DAG mailbox servers, one into primary site with witness folder on a HUB/CAS server and the second mailbox server in DR site and a very very fast and secure dedicated line between them. All users are into primary site, so all databases would be always active on primary mailbox server, with all passive copies on secondary mailbox server. In the case of failure of primary site, suppose both primary mailbox server and witness go down, will be the secondary mailbox server able to support users?
We have a VLAN for DAG replication, Recoverpoint (SQL Data), and right now SMTP Shadow replication is going over with the production traffic.
Should shadow replication be limited to the site? Should it go across the WAN? If so should it be on a separate VLAN?
We have two Exchange 2010 boxes and are attempting to use DAG (similar to this setup except we are less than 1 mile away from the remote office)
However we were wondering if it is possible to manually copy and paste the files necessary for replication before enabling it, so as to speed up the process.
Thanks,

I'm trying to create an exchange domain service account. I'd like to define the rights in a Group Policy Object.
since this is for both a 2 node DAG, and 2 node CAS Array, I need to know the rights for services like "Exchange Server RPC Client Access" service, etc.
Does anyone know where I can find these GPO rights?
You may have just seen my other question here.
One of the other things the client failed to tell me was that they also wanted a DAG between the U.S. and a site in Europe. I had never set up a DAG, but I did it, and opened a case with Microsoft to make sure I did it right. It seems fine, and everything replicates.
The problem is that when I attempted to test it failing over, it would not. I found information here that leads me to believe they may also need a hardware network load balancer, but I do not fully understand how it works, and how it makes Exchange understand that it has failed over. Could anyone explain that to me? I have looked.
Thank you.
