Filed under: General — telnet25 @ 12:45 pm

Here is general guidelines along with MS best practices how to configure NIC card settings when setting up Exchange 2010 DAG servers. Use this as reference for your deployments.

Exchange 2010–Mailbox DAG Network configurations for the purpose of this document we will call

  • NIC1= Production (it has DGW configured)
  • NIC2=Replication (it does not have DGW, Use NetSH to configure static persistent route)

NIC Binding order = Production NIC is listed first, Replication NIC is second other NIC if available in any order….

NetSH Interface ip show route
DGW = 10.80.3.1 in this example

netsh Interface ipv4 add route 10.80.3.102/32 "inside" 10.80.3.1 store=persistent

To delete any static route

netsh interface ipv4 delete route 10.0.0.0/8 "Internal" 10.0.0.5

See the Static route

netsh interface ip show route

Reset the Interface ( very powerful)

netsh interface tcp reset
