I hava a home network with 5 computers, 2 of them go to standby with no problem, the other 3 wake up soon after standby. If I disable wake on lan they stay asleep. Is there some program I can run on the ones that wake up to log network activity in order to identify what is causing the wake up??? All computers are running XP. Thanks for any help. Mike

I've checked the bios settings and they all match, wake on lan is enabled on all of them. the hardware varies from machine to machine. All will wake up when accessing them from another computer. I suspect it's related to one of the machines " checking" the network but I'm not sure which one. Mike
