Hi Jason,

I can not reproduce the problem. Here it takes less than a second. But
it may depend on the DNS resolution. Have you tried to pass an IP
instead of server name to the client?

I have added the current time in the output, so I can what happens. Of
course, you have to be sure that the clocks of both machines are in
sync.

Here is the code I tries:

using System;
using System.Windows.Forms;

namespace Samples {
public class MyRemoteObject: System.MarshalByRefObject {

public MyRemoteObject() {
Console.WriteLine("{0} - MyRemoteObject Constructor Called",
DateTime.Now);
}

public String ComputerName() {
Console.WriteLine("{0} - ComputerName Called", DateTime.Now);
return SystemInformation.ComputerName;
}
}
}


using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using Samples;

namespace Samples {
class SimpleServer {
static void Main(string [] args) {
ChannelServices.RegisterChannel(new TcpChannel(8085));

RemotingConfiguration.RegisterActivatedServiceType(typeof
(MyRemoteObject));

Console.WriteLine("Press return to exit");
Console.ReadLine();
}
}
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Activation;
using Samples;

namespace Samples {
class SimpleClient {
static void Main(string[] args) {
if (args.Length == 0) {
Console.WriteLine("usage: simpleclient HostServerName");
return;
}

Console.WriteLine("{0} - Started", DateTime.Now);

object[] url = { new UrlAttribute("tcp://" + args[0] + ":8085") };

MyRemoteObject robj = (MyRemoteObject) Activator.CreateInstance
(typeof(MyRemoteObject), null, url);
Console.WriteLine("{0} - Remote call: {1}", DateTime.Now,
robj.ComputerName());
Console.WriteLine("{0} - Remote call: {1}", DateTime.Now,
robj.ComputerName());
}
}
}

My output on the client is:

C:\temp\cs_test>simpleclient test1
7/31/2004 5:57:32 PM - Started
7/31/2004 5:57:33 PM - Remote call: TEST1
7/31/2004 5:57:33 PM - Remote call: TEST1

and from the server:

C:\temp>simpleserver
Press return to exit
7/31/2004 5:57:33 PM - MyRemoteObject Constructor Called
7/31/2004 5:57:33 PM - ComputerName Called
7/31/2004 5:57:33 PM - ComputerName Called
