Lan Manager
"LAN Manager" can refer to two main things: a historical network operating system from Microsoft or, more broadly, a job title for someone who manages a local area network (LAN). The operating system was a precursor to Windows NT, while the job title is a modern role responsible for network administration, maintenance, and security. A third, related concept is the LM hash, a now-insecure authentication method used by the original LAN Manager and early versions of Windows.
