Routine Description:

    This routine does all the munging of DS entries to make this machine look
    like a remote boot client.

Arguments:

    pBuffer - Pointer to any arguments passed in the to do item.

    Length - Length, in bytes of the arguments.

Return Value:

    STATUS_SUCCESS if it completes the to do item properly.
