Active Network Monitor (ANM) is a tool for the day-to-day monitoring of computers on a network. ANM runs under Windows NT/2000/XP. It lets Systems Administrators gather information from every computer (even Windows 9x/Me computers) on the network without installing server-side applications on any of these computers. ANM's centralized network monitoring interface makes it easy for you to monitor the entire network. Installed on one computer, ANM's powerful technology stores and compares its received data. Administrators can monitor every important parameter on their remote computers, and take snapshots of the systems and network status for future comparisons and change tracking.

ANM has a flexible, plug-in based architecture that lets you add new modules on demand. Each plug-in performs a task and displays its information in its own window. ANM ships with a predefined, constantly growing list of plug-ins, including plug-ins for monitoring services, devices, installed applications, disks, shared resources, hardware resources (IRQs, I/O, DMA and Memory), users, local groups, global groups and so on.
