I’m working on a retail network consisting of some 800 shops. There are about 6 win2k prof clients in each shop. What I want to do is use wake on lan to bring up any machine on the network that has been switched off (as shop staff are prone to do when they go home). The wake on lan works fine, but what I need is a way of getting the mac addresses for each client from DHCP. Currently, we use getmac from the reskit and have built up a DB of mac addresses, but if I could get that info live from DHCP then there would be no problems with network cards being swapped, or new machines added that have not yet been ‘getmac’ed etc. Note- all I’m interested in is how to get the macs from DHCP, no workarounds please ! Any ideas how to do this ?? a cool2000 points to whoever provides the answer.
