IBM LAN Server

IBM LAN Server started as a close cousin of Microsoft LAN Manager and first shipped in early 1988. It was originally designed to run on top of Operating System/2 Extended Edition. The network client was called IBM LAN Requester and was included with OS/2 EE 1.1 by default. (Eventually IBM shipped other clients and supported yet more. Examples include the IBM OS/2 File/Print Client, IBM OS/2 Peer, and client software for Windows.) Here the short term LAN Server refers to the IBM OS/2 LAN Server product. There were also LAN Server products for other operating systems, notably AIX (now called Fast Connect) and OS/400.
