The WOL feature does not seem to be working for us. When OpUtils was installed and upgraded to SP2, we were able to utilize the WOL feature to wake up computers one at a time.
However, when we created a full list of IP addresses and did a batch WOL command, this feature then stopped working. After that, we lost the ability to do a WOL to single IP addresses.
The only way we could get this feature back was completely uninstall and reinstall.
