Hi Guys, I was just doing R & D in my Test Lab on Exchange Two Node Cluster : Active/Passive. I was testing the failOver. I have two node, node1 and node2, Node1 is active Scene1 -While disabling the Node1 Public Nic - It should failover to Node2, But its not happening - Resources is not transferring to node2, And while opening the Cluster Admin on Node2 It says netwok name not found, Same for Scene2. Scene2 -If i directly switching off my active node then also - the failover is not happening. -: But if I am restarting the active node - then i can see the transferred resources on Node2. I am surprising that - If this is the scene of FailOver, Then how can we relay on cluster. Friends - Please suggest.. I am waiting for your response......... Thanks and Regards, Ashwini Kumar :-:

Issue description: Failover didnt happen after isolated active node Please provide detailed error info, the warning or error info in the two different scenarios, check the application log after reproduce the issue

What version of Windows and Exchange Server do you run? The cluster will automatically initiate a failover if it recognizes that the public IP failed because this cluster resource has the Affect the Group property set in Exchange Server 200x. I assume you have made a mistake either in the setup of Exchange or in your test case. This usually works bullet proofed.
