In your example, if you want to connect to an OPC server residing on a remote machine, the name or IP address of the computer goes into the first argument of the SubscribeEvents call. So, you would have something like
client.SubscribeEvents("", "Kepware.KEPServerEX_AE.V6", 1000);
If possible, the first tests should be done with server residing on the same machine as client, because to set up DCOM properly can drive even an experienced professional crazy.

It is not clear why you are not seeing any events. Have you tried some other OPC A&E client to verify that events should be flowing?

Best regards

I try to get event with a KepWare server. ("Kepware.KEPServerEX_AE.V6") .

How to configure the IP adress ?

I try to configure event like this, but there a never event and no error messages.

Can you help me :) :
string srvName = "Kepware.KEPServerEX_AE.V6";
string adress = "";
using (var client = new EasyAEClient())
    var eventHandler = new EasyAENotificationEventHandler(client_Notification);
    client.Notification += eventHandler;
    client.EventingFailure += fail;
    int handle = client.SubscribeEvents("", srvName, 1000);
    Console.WriteLine("Processing event notifications for 10 seconds...");
    Thread.Sleep(10 * 1000);
static void client_Notification(object sender, EasyAENotificationEventArgs e)
    if (!e.Succeeded)
        Console.WriteLine("*** Failure: {0}", e.ErrorMessageBrief);
    if (e.EventData != null)
static private void fail(object sender, OpcLabs.BaseLib.FailureEventArgs e)
     var s = e.ToString();
