I can currently use EMCO wol free software to turn computers on across my network. EMCO works great even across subnets. I would like to be able to use dos to shut the computers off. I can turn off a computer on another subnet if I specify the mac address and the IP address. I need to be able to turn it on with just the mac address. I can do this on the local subnet but not across the network to other subnets. I can use either of these programs to turn on computers on the local subnet without ip address or or another subnet, using the ip address.
Can anyone tell me how I can use dos wol computers without using the ip address. I dont want to use the ipaddress because they are dynamic.
