LanHelper is network management software which integrates NT administration utilities and LAN monitoring features, and is designed for remote management of Windows servers and workstations. LanHelper provides administration functionality such as Wake-on-LAN, shutdown, users management, groups management, services management, sessions management, task schedule, and more. No server program is required to install on remote computers.
Detailed logs help LAN administrators to solve network problems. The IP scanner and LAN scanner collect machine data, and the machine data can be managed with XML and groups features. LanHelper can detect the computer's status and monitor its availability. Once failure or problem is detected, LanHelper will alert network administrator, or automatically perform Wake-On-LAN and shutdown actions.
