The Intel(R) SOL LMS Extension (System Out-of-Band Management Local Management Service Extension) is a Windows driver related to Intel's Active Management Technology (AMT). AMT is part of Intel vPro technology, which is primarily used for remote management of PCs in enterprise environments. The SOL stands for Serial Over LAN, and it allows administrators to manage computers remotely even when the system is powered off or has no operating system running. The LMS stands for Local Management Service, which is a service that works with AMT to facilitate local management operations.
