Hi!
1. For shutdown, you can create a Client job, including there a "Power Control" task and set ability to "Defer a task" with message. (But I don't remember that it is possible to cancel this receive client job... Need to check on SMP Console, what it offers.)
- Or include in this Client job this script task:
1. Open Symantec Management Console
2. Select "Manage -> Jobs and Tasks"
3. Select "Run Script"
4. Under Script Type, select "Command Script"
5. Write the script:
shutdown -r -t XXX(seconds) -c "Machine will restart in XX minutes, Please save all your documents."

2. For WOL and Welcome message, you can try to use Client job, where first task is WOL and second will be a script task, which will execute .vbs script to show a welcome message box.
Thanks,
