string dirResults = "";
ProcessStartInfo psi = new ProcessStartInfo();
Process proc = new Process();
if (proc.Id != 0)
{
psi.FileName = "nbtstat";
psi.RedirectStandardInput = false;
psi.RedirectStandardOutput = true;
//proc.StartInfo.UseShellExecute = false;
psi.Arguments = "-a " + IP;
psi.UseShellExecute = false;
proc = Process.Start(psi);
dirResults = proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
}

//匹配mac地址
Match m = Regex.Match(dirResults, "\\w+\\-\\w+\\-\\w+\\-\\w+\\-\\w+\\-\\w\\w");

//若匹配成功则返回mac，否则返回找不到主机信息
if (m.ToString() != "")
{
return m.ToString();
}
else
{
return "找不到主机信息";
}

一到了这句就拒绝访问，本地一切OK 一道服务器就错误了。

说得很清楚，拒绝访问，权限问题。主进程需要以管理员身份运行。

是否权限的问题，是否32位程序在32位系统编译器编译过后在32位系统下运行。
