While this is not really SQL specific, does anyone have any information on where in the binding order the iSCSI networks should be on a Windows cluster?

I am dealing with an issue where the SQL resource group fails on a Windows cluster comprised of two VMWare virtual machines. The quorum drive and the SQL disk resources are all iSCSI using the Windows iSCSI initiator. Intermittently (usually in the early AM) the cluster will report losing connection to the storage and losing quorum. The SQL resource group will not failover or restart until it is discovered and manually restarted at the beginning of the business day. I'm concerned that the network binding order may be negatively impacting the iSCSI communication.

Thanks in advance!

another user encountered this previously and the recommendation from Microsoft was the following (in order from highest to lowest priority)

Public
Private
iSCSI


Personally I have always used the following

Public
iSCSI
Private

The Public network is usually always enabled for all cluster communication so based on that I set the Private to a lower priority.
