I have three brand new servers.
Mail (Exchage 2010) (Server 2008 R2)
DC1 (Server 2008 R2)
DC2 (Server 2008 R2)
I set up DC1 and the Mail server first. Got my certificate, set up the autodiscover, OWA, Outlook Anywhere, etc. I set up three users initially. Tested and no errors, no problems. I installed the 2nd DC. This DC will be in a different location for users to authenticate locally and then access email over a MPLS circuit. Currently these servers are on the same network and they seem to be communicating.
I installed the other DC, set up additional users, and all is fine. However, once I take the DC2 ofline to get it ready to ship, the new users cannot login and the offline address book updates and has only the first three users in it. What am I missing?
