Event ID: 121 Source: MSiSCSI

The firewall exception to allow Internet Storage Name Server (iSNS) client functionality is not enabled. iSNS client functionality is not available.
This problem might be caused by several Windows 2008 updates (KB979687, KB979688, KB981957, KB982132, KB2207566, KB2296011, KB2360131, KB2387149 or KB2345886).

In my case it did not help to stop and restart the iSNS and iSCSI Services on target and initiator side of iSCSI. A reboot was necessary to reestablish the iSCSI connection.
