Map Network Drive vs. iSCSI Map Network Drive vs. iSCSI sysengineer1 (TechnicalUser) (OP) 17 Feb 16 20:48 What is the difference in Windows when selecting 'Map Network Drive' vs. configuring an iSCSI Initiator in terms of protocols and benefits/weaknesses etc.? Thanks in advance RE: Map Network Drive vs. iSCSI BobMCT (IS/IT--Management) 3 Aug 16 04:28 My guess: protocol! Map a network drive uses the SMB protocol (Server Message Block - SAMBA) and iscsi initiator is an entirely different protocol which wraps scsi commands and data frames in a network container. iscsi, in most cases, would be used to connect to SANs and (large) production servers. Just my 2 cents worth.
