    Wake-on-lan does not work. When pushing the package, the WOL magic packet was sent to different IP address instead of the real IP address of the client.


    Root Cause

    If previously multiple NIC cards were in use, this multiple NIC card information is stored in the Inventory information. Wake-on-lan will send the magic packets to the very first NIC card IP address in the NIC cards list. So if that first NIC card has been decommissioned and still remains in the inventory information, the WOL magic packet will still be sent to it causing the target device to nit receive the WOL magic packet and thus it is not woken up.


    This can be checked by going to "Inventory","Network","TCPIP" in the inventory to see if there are multiple NIC's stored there and if the first one has been decommissioned already (not currently in use by the client).



    Refresh the NIC card information by deleting the client from the console and then running the inventory scan again from the client side to refresh the inventory data.
