IBM LAN Server
open-in-new
<p>IBM LAN Server is a discontinued <a href="/facts/Network_operating_system/K9MlJLI3">network operating system</a> introduced by <a href="/facts/IBM/QszA7nwd">International Business Machines (IBM)</a> in 1988. LAN Server started as a close cousin of <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a>'s <a href="/facts/LAN_Manager/JLXQQlGT">LAN Manager</a> and first shipped in early 1988. It was originally designed to run on top of <a href="/facts/OS%2f2/uVBl6ItP">Operating System/2 (OS/2)</a> Extended Edition. The network client was called IBM LAN Requester and was included with <a href="/facts/OS%2f2/uVBl6ItP">OS/2</a> EE 1.1 by default. (Eventually IBM shipped other clients and supported yet more. Examples include the <i>IBM OS/2 File/Print Client</i>, <i>IBM OS/2 Peer</i>, and client software for <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a>.) Here the short term <i>LAN Server</i> refers to the IBM OS/2 LAN Server product. There were also LAN Server products for other operating systems, notably <a href="/facts/AIX_operating_system/cRWERua2">AIX</a>—now called Fast Connect—and <a href="/facts/OS%2f400/lsIRAUvn">OS/400</a>. </p>
