我连接到本地KepServerEX，现在我正在尝试KepServerEX使用 c# 连接到远程。

我已将DCOM我的计算机配置为连接到远程服务器，但不幸的是我仍然无法连接到远程KepServerEx。

我使用了这个命令：

KepServer.Connect("KEPware.KEPServerEx.V4", remoteServerIP)

并为我的 PC 配置了 DCOM。

这是我的代码：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    OPCServer KepServer;
    OPCGroups KepGroups;
    OPCGroup KepGroup;
    OPCItems KepItems;
    OPCItem KepItem;
    string strHostIP = "";
    string strHostName = "";
    bool opc_connected = false;
    int itmHandleClient = 0;
    int itmHandleServer = 0;

    private void GetLocalServer()
    {

        IPHostEntry IPHost = Dns.Resolve(Environment.MachineName);
        if (IPHost.AddressList.Length > 0)
        {
            strHostIP = IPHost.AddressList[0].ToString();
        }
        else
        {
            return;
        }
        IPHostEntry ipHostEntry = Dns.GetHostByAddress(strHostIP);
        strHostName = ipHostEntry.HostName.ToString();

        try
        {

            KepServer = new OPCServer();
            object serverList = KepServer.GetOPCServers(strHostName);
            foreach (string turn in (Array)serverList)
            {
                bool bl = turn.Contains("KEPware");
                if (bl == true)
                    cmbServerName.Items.Add(turn);
            }
            cmbServerName.SelectedIndex = 0;
            btnConnLocalServer.Enabled = true;

        }
        catch (Exception)
        {
        }

    }

    private bool CreateGroup()

            KepItems = KepGroup.OPCItems;

        }
        catch (Exception)

最后我解决了我的问题。我很高兴与您分享我的问题。

首先，您使用KepServer.Connect(remoteServerName, remoteServerIP);方法连接到远程服务器。

您必须为您的客户端和服务器计算机配置 DCOM。可以参考链接：http://support.sas.com/rnd/itech/doc9/admin_oma/sasserver/comdcom/xpsp2.html。

这里重要的是，您必须在我的客户端计算机上创建一个本地用户，该用户与服务器上的用户名和密码相同。

您可以参考链接：http://www.elmajdal.net/win7/how_to_create_a_password_for_a_user_account_in_windows_7.aspx创建用户名密码。

我希望这可以帮助你。
