IBM LAN Server is a discontinuednetwork operating system introduced byInternational Business Machines (IBM) in 1988. LAN Server started as a close cousin ofMicrosoft'sLAN Manager and first shipped in early 1988. It was originally designed to run on top ofOperating System/2 (OS/2) Extended Edition.[1] The network client was calledIBM LAN Requester and was included withOS/2 EE 1.1 by default.[2] (Eventually IBM shipped other clients and supported yet more. Examples include theIBM OS/2 File/Print Client,IBM OS/2 Peer, and client software forMicrosoft Windows.[3]) Here the short termLAN Server refers to theIBM OS/2 LAN Server product. There were also LAN Server products for other operating systems, notablyAIX[4]—now called Fast Connect[5]—andOS/400.[6]

LAN Server pioneered certain file and print sharing concepts such as domains (anddomain controllers), networkedCOM ports, domain aliases, and automatic printer driver selection and installation.[citation needed]
IBM pledged that OS/2 LAN Server will remain a strategic offering, announcing that version 1.3 was shipped ahead of schedule last week. They also pledged to fully support both LAN Server and NetWare equally.
