CF Instance not starting in copied JRun cluster

We have 2 virtual servers each with 2 CF instances in its own JRun cluster.  These 2 servers are in a Microsft NLB.  Using FusionReactor we can see that the NLB is equally distributing the load between the 2 servers however on only 1 server the load is not equal between the 2 CF instances.  We copied the first server, changed the IP and that is the second server.  Does any one know what I can do to fix or find out more information as to what this problem is?

    If you copied the servers the JRun instances have the same JNDI name on both servers. That is not a supported configurations, names in a cluster must be unique. They also need different server.id properties if you want to do any form of load direction through the connectors.

    So does this mean I can remove the cluster and create a new one with the same CF instances in it but using a different name? So I would end up with:

    server1 -> cluster1

    server2 -> cluster2

    I do not understand the extra server.id properties you are talking about can you point me to something that explains this?

    No. You need to recreate the CF instances with unique names. If you do that the server.id (from the connector.properties file) will also be unique for each instance.
