I have this scenario and cannot find an answer. Please help.
I have 2 locations A and B seperated by a WAN. Each site will contain 1 Exchange 2010 server that will replicate a single database. I understand a DAG will need to be created with a Witness server. The problem is where do you place the witness server as if the WAN goes down between the sites then according to what i have read the site without the witness server database will go offline until a witness server is found. Is that right? if so that means you would have to replicate the witness server as well! Is there something I have missed?
