MarkCEllam -> DAG's Across WAN's (2.Jul.2010 8:28:53 AM)
I've setup a brand new 2008 R2 Domain. The task is to setup 2 x Exchange 2010 across a WAN with DAG's. Site 1 has the fist AD server. Site 2 has 2 AD servers. All Global Cat. Replication had issues but has seemed to settle down and both site replicate AD. I was getting 1925 RPC errors but they seem to have vanished.
2 Sonicwall Routers (4060/NSA240) with a VPN tunnel. (Windows broadcast traffic is not enabled currently)
Site one = 194.x.x.x
Site two = 77.x.x.x Subnets on 255.255.255.0 Gateways are the Sonics
Both site can resolve DNS and ping each other (Firewalls permiting)
One NIC each with an IP of 18.104.22.168 other with 77.x.x.15
Setup-On site one Exchange server installed. Site two. Exchange server installed and they can see each other across the WAN. The management console looks good and both Databases are visible on Each server and a Local WS console. (I think that covers everything)
FSW is created and added to trusted Exchange on site one. DAG group created and visible in AD. When I click on the DAG group this message appears.

It looks to be RPC related possibly Firewall. Any thoughts would be helpful
