DirectoryEntry 使用哪些端口？

我的目标是从远程服务器获取网站名称列表。但我得到了例外：

RPC 服务器不可用。

这是代码：

    public List<string> GetWebSites(string serverIP)
    {
        List<string> names = new List<string>();
        DirectoryEntry Services = new DirectoryEntry(string.Format("IIS://{0}/W3SVC", serverIP));
        Services.Username = "user name";
        Services.Password = "password";
        IEnumerator ie = Services.Children.GetEnumerator();
        DirectoryEntry Server = null;

        while (ie.MoveNext())
        {
            Server = (DirectoryEntry)ie.Current;
            if (Server.SchemaClassName == "IIsWebServer")
            {
                names.Add(Server.Properties["ServerComment"][0].ToString());
            }
        }

        return names;
    }

当计算机上的防火墙关闭时，这可以正常工作。

我需要知道的是，DirectoryEntry 使用了哪些端口？或者有没有其他方法可以在不关闭防火墙的情况下获取网站名称？

My goal is to get the list of web site names from remote server. But I'm getting the exception:

The RPC server is unavailable.

Here is the code:

    public List<string> GetWebSites(string serverIP)
    {
        List<string> names = new List<string>();
        DirectoryEntry Services = new DirectoryEntry(string.Format("IIS://{0}/W3SVC", serverIP));
        Services.Username = "user name";
        Services.Password = "password";
        IEnumerator ie = Services.Children.GetEnumerator();
        DirectoryEntry Server = null;

        while (ie.MoveNext())
        {
            Server = (DirectoryEntry)ie.Current;
            if (Server.SchemaClassName == "IIsWebServer")
            {
                names.Add(Server.Properties["ServerComment"][0].ToString());
            }
        }

        return names;
    }

this works fine, when firewall is turned off on the machine.

What I need to know is, which port(s) are used by DirectoryEntry?
or is there any other way to get web site names, without turning off firewall?
