    I am using .NET Remoting to transfer a file over a network in the form of a
    byte array. I am registering the server using:
    TcpChannel chan = new TcpChannel(8085);
    ChannelServices.RegisterChannel(chan);
    RemotingConfiguration.RegisterWellKnownServiceType(typeof(HICONServer),
    "C4I.EDMSIM.HICON", WellKnownObjectMode.SingleCall);

    and calling the function using:
    byte[] buffer = _hiconServer.chooseStation(stationID);

    the chooseStation function returns the byte array:

    FileStream fs = new FileStream(_dsa.dbName, FileMode.Open);
    BinaryReader br = new BinaryReader(fs);
    buffer = br.ReadBytes((int)fs.Length);
    br.Close();
    return buffer;

    This works fine when the client and server are both on the same machine, and
    this method has worked in another application deployed in a large scale
    environment. For some reason, the function never returns. I have added
    trace information and the "return buffer" line is getting called, my network
    activity jumps and anywhere from 1MB to 4MB gets sent and then nothing
    happens.

    I have two questions:
    1. Should I being doing this another way (splitting up the byte array, and
    returning pieces at a time, this probably makes more sense, but I didn't
    have problems in the past).
    2. Is there some way I can tell if the remoting call has hung up.
