EMCO WakeOnLan Free - Version 1.2.3 A free visual Wake on LAN (WOL) utility allows you to power up remote PCs by sending them a magic (WOL) network packet. The application is designed to operate in enterprise networks, which may include domains, workgroups and multiple subnets, to power up one or multiple remote PCs within the scope of a single operation. The centralized WOL operation can be initiated with just one mouse click. You don't need to enter MAC addresses of remote PCs in order to wake them up remotely. The application retrieves MAC addresses automatically using four MAC detection mechanisms.Depending on your network configuration, the application allows you to use different Wake-on-LAN packet transmission methods to be sure that the WOL packet will not be blocked by your network devices. You can use unicast, directed broadcast, local subnet or Internet transmission methods, or all of the above at the same time.
