Lan Core is software that lets you build a thin client network on a Windows operating system. It was originally designed to work in a server or workstation with Windows XP Professional and using the native remote desktop protocol or RDP. To this end, the Lan Core package includes: (1) the Preboot Execution Environment or PXE service, a server application used to boot the thin clients (also referred as terminals or clients) in a local area network; (2) the thin client operating system (Thin OS), an embedded system based on Linux; and (3) an interface application used to manage the PXE service and thin clients. The thin clients' boot is done through a local area network (LAN), and it is based on the Preboot Execution Environment (PXE) protocol. In order to do it, Lan Core also provides two additional services: a DHCP server and a Trivial FTP server for Windows, used to assign IP addresses and transfer boot files, respectively.
