Unidentified network.

I have setup two windows  server 2008 R2 server to exchagne 2010. I have dual nic on both  server. One nice configue for LAN another one for NLB. The NLB was not able to detect as Domain network. When i first set it up it was working ok. We power down the server becasue of the relcoate. And now the NLB nic was not able to detect as Domian Network,, it detects it as Unidentified network.

How can i have this nic to detect as domian network or any way it?

ipv6 disalbed, Binding are ok.

you mean the "NLB" nic is connected to a separte network just between the 2 servers for heartbeat ?

If so then it SHOULD be identified, it won't be anything else this is not a problem

yes example,, Two CAS Server would be 10.1.1.101 and 10.1.230.102
NBL Nic: 10.1.1.104  & 10.1.1.105,, and only with subnet Mask

My connection was ok when i frst set it up. But now it detected as Unidentified network.

Two Servers: LAN and NLB Nice
Server 1: Lan:192.168.1.1
                NLB: 192.168.1.2
Server2: LAN: 192.168.1.3
                NLB: 192.168.1.4
CASARRY IP: 192.168.1.5
ipv6 is off, binding is LAN nic first

wait do you mean you actually have LAN and NLB NIC connected to the same switch ? the NLB should be a dedicate vlan on another network

excuse my last comment i read something wrong


1. if you destroy your NLB cluster can you ping all IPs from your LAN ? i.e. 192.168.1.1 192.168.1.2 192.168.1.3 192.168.1.4 ?
2. what NLB mode are you using unicast or multicast ?
3. what is happening when you build your cluster which IP becomes not pingable ?
