The free Wake on LAN tool can be used to boot machines in the LAN from remote. It allows you to boot multiple machines simultaneously. To wake-up a machine from remote, follow the steps below:
The Wake-On-LAN functionality is generally disabled by default. The option to enable Wake-On-LAN is different with each computer manufacturer. The most common method adopted across different PC's are as follows:
In some Windows OS, the drivers can enable the Wake ON LAN features of network adapters. For example in Windows 2000, click Power Management tab and under the Adapters properties, select the option Allow this device to bring the computer out of standby.
Alternatively, you can also check the Advanced setting table for parameters related to Wake on LAN and Waking on "Magic Packets" and enable them.
For Wake On LAN to work on computers with older PCI busses, a WOL cable must be installed between the Network Card and the Motherboard. Because this requires opening the computer case, we advice you to contact your PC manufacturer for specific instructions.
