如何获取本机ip地址？具体说明如下！
为了方便人家设置ip地址。故写一个可以设置ip地址的界面而且可以获取ip地址。和利用网上邻居属性设置ip地址一样的功能。
1、可以设置自动获取ip地址
2、可以手动设置ip地址，输入栏位最好也是 . . . .也要有子网掩码，网关，DNS,WINS,等设置。
3、用一个按钮事件，点击开IE浏览器的属性--〉连接对话框。
就这么多啦。希望大家能帮我小弟一忙，给点意见，最好有源码或提供一些资料参考。谢谢各位！！！

第一二个问题可以使用System.Management类解决
如果是winform的话，需要添加对System.Management.dll的引用
然后使用下面的类就可以实现你的前2个要求：
namespace modify
{
public class ChangeIP
{
public static readonly System.Version myVersion = new System.Version(1, 1);
private ManagementBaseObject iObj = null;
private ManagementBaseObject oObj = null;
private ManagementClass mc = new ManagementClass( "Win32_NetworkAdapterConfiguration ");
private readonly ManagementObjectCollection moc;
/// <summary>

/// <code>

/// string[] ipList = new string[]{ "192.168.0.253 ", "192.168.0.250 "};
/// string[] subnetList = new string[]{ "255.255.255.0 ", "255.255.255.0 "};
/// o.ChangeTo(ipList,subnetList);
/// </code>
/// </summary>
public ChangeIP()
{
moc = mc.GetInstances();
}
/// <summary> cortrol </summary>

{
if (!(bool)mo[ "IPEnabled "]) continue;
iObj = mo.GetMethodParameters( "EnableStatic ");
iObj[ "IPAddress "] = ipAddr;
iObj[ "SubnetMask "] = subnetMask;
oObj = mo.InvokeMethod( "EnableStatic ", iObj, null);
}
}

iObj = mo.GetMethodParameters( "SetGateways ");

iObj = mo.GetMethodParameters( "SetDNSServerSearchOrder ");
iObj[ "DNSServerSearchOrder "] = dnsServer;
oObj = mo.InvokeMethod( "SetDNSServerSearchOrder ", iObj, null);
}
}

你可以用SqL Server的管理器试下可否在家中看到相应的服务器名，如果不可以看到的话，应该是SQL的设置问题或防火墙等其它因素
