The TCP/IP stack can't bind

I have just upgraded our 6.5.3 servers to 7.0 and I now get the error:

The TCP/IP stack can’t bind a network address to a TCP socket, please verify that the TCP stack has been properly initialized

We have also moved the data to new hardware. We have two servers in a cluster. When I start the servers I get major error and they can not find each other either on the cluster or the other ports. They are now in a test network.

I have searhed for similar post here but my notes.ini file looks ok as far as I can see.

Did you transfer the ip-address from the old to the new server?

IN the past, were you using a separate port for your cluster replication traffic? Typically I have seen these errors when you primary NIC is correct and the server is responsive but is attempting to cluster replicate across a secondary NIC. If the secondary NIC is not configured properly, you may receive this error.

Hope this helps.
