Routine Description:

    This routine binds to the servicename on the server. A binding handle is
    returned if successful.

    If the service on the server is not available, this client will try to
    start that service then bind to it.

Arguments:

    servername  - the system name where SCE server service is running on

    servicename - the pipe (port) name of SCE server

    networkoptions  - the network protocol options

    pBindingHandle - the binding handle to output

Return Value:

    NTSTATUS
