iSCSIPrt Event ID’s 7, 20, and 34

Question : iSCSIPrt Event ID’s 7, 20, and 34

On Sunday we applied Windows updates through WSUS to all servers.  When I came in Monday morning 4 servers had iSCSIPrt errors (Event ID 7, 20, and 34) reporting every few minutes.  These servers are Windows Server 2003 R2 SP2 servers with shares to a LeftHand SAN solution over iSCSI.  We were able to fix 2 of the servers by updating the iSCSI Initiator to the latest version and removing the LeftHand MPIO software but my two Exchange servers that are in a cluster still report all errors.  I have changed out CAT6 cables with no change and I have checked the switch to verify no packet errors.  Suggestions?
