using System.Management;

......

//连接远程电脑
ConnectionOptions options = new ConnectionOptions();
options.Username = textBox1.Text;
options.Password = textBox2.Text;
ManagementScope scope = new ManagementScope(textBox3.Text,options);
try
{
scope.Connect();
ManagementObject disk = new ManagementObject(scope,new ManagementPath("Win32_logicaldisk='i:'"),null);
disk.Get();
textBox6.Text = disk.Path + textBox4.Text;
FileInfo fi= new FileInfo(disk.Path + textBox4.Text);
FileStream fs=fi.Create();
StreamWriter sw=new StreamWriter(fs);
sw.Write(textBox5.Text);
sw.Close();
}
catch(Exception ex)
{
textBox5.Text = ex.ToString();
}

line: scope.Connect();返回如下错误信息
System.Runtime.InteropServices.COMException (0x800706BA): RPC 服务器不可用。
at System.Management.ThreadDispatch.Start()
at System.Management.ManagementScope.Initialize()
at System.Management.ManagementScope.Connect()
at WindowsApplication1.Form1.button1_Click(Object sender, EventArgs e) in c:\documents and settings\wjd\my documents\visual studio projects\windowsapplication1\windowsapplication1\form1.cs:line 215

再试试上面仁兄的方法

UNC, mappdive都要完全的权限, 连FTP和web站点都不让建,估计悬

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace IISWatcher

[StructLayout(LayoutKind.Sequential)]
public class NetMappingDrive
{
public int dwScope;
public int dwType;
public int dwDisplayType;
public int dwUsage;
public string LocalName;
public string RemoteName;
public string Comment;
public string Provider;

//如果正确，返回值是0；否则错误。网络访问错误代码53。
[DllImport("mpr.dll", EntryPoint = "WNetAddConnection2")]
public static extern uint WNetAddConnection2([In] NetMappingDrive lpNetResource, string lpPassword, string lpUsername, uint dwFlags);

[DllImport("Mpr.dll")]
public static extern uint WNetCancelConnection2(string lpName, uint dwFlags, bool fForce);

public NetMappingDrive(string LocalDrive, string NetPath,string Username,string Password)
{
this.dwScope = 2;
this.dwType = 1;
this.dwDisplayType = 3;
this.dwUsage = 1;
this.LocalName = LocalDrive;
this.RemoteName = NetPath;
this.Provider = null;

}

public uint CreateDrive(string Username,string Password)
{
return WNetAddConnection2(this, Password, Username, 0);
}

public uint DeleteDrive()
{
return WNetCancelConnection2(this.LocalName, 1, true);
}
}

//添加映射网络驱动器调用的代码如下：

//NETRESOURCE myNetResource = new NETRESOURCE();

//myNetResource.dwScope = 2; //2:RESOURCE_GLOBALNET

//myNetResource.dwType = 1 ; //1:RESOURCETYPE_ANY

//myNetResource.dwDisplayType = 3; //3:RESOURCEDISPLAYTYPE_GENERIC

//myNetResource.dwUsage = 1; //1: RESOURCEUSAGE_CONNECTABLE

//myNetResource.LocalName = "T:";

//myNetResource.RemoteName = yourNetworkPath;

//myNetResource.Provider = null;

//uint nret = WNetAddConnection2( myNetResource, pwd, username, 0);

//

////删除映射网络驱动器调用的代码如下：

//uint nret = WNetCancelConnection2( yourNetDriveName, 1, true);

这个类可以帮你

先把远程目录转换为本地映射

然后写

写完后把映射删掉
