Hi Sergei,
Thanks a lot for your reply.
Actually, I am using tickle method for wake up the group of PCs.
Altiris NS server will find a powered on client in target subnet to send boardcast magic packet.
I don't know which powered on client is selected.
=========================================================================
So, I test it by setup an environment which has only 3 clients winXP PCs (ATS-GHOST02, ATS-GHOST03 and ATS-GHOST05) and a NS server (TEST-ATS) (attached the setting "setting.jpg")
I power off ats-ghost03 and 05 and start "tickle client" task (attached "Tasks.jpg").
It is found no new log generated in the log file of ats-ghost02 and no magic pocket captured by wireshark.
But I found it is completed the task in log of NS server (attached "a - Copy of NS.log").
=========================================================================
Note:
If I wake up ats-ghost03 only, it works fine. And I can captured the magic pocket send out by wireshark.
Thanks.
