无法从 C# 执行 TekRadius CLI

Question

TekRadius 是我想通过我的 ASP.NET 应用程序访问的 Radius 服务器。我首先尝试使用 C# 直接执行 TekRadius CLI。但它没有用。现在我正尝试通过 CMD 调用它来通过 C# 代码执行它，如下所示：

System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.CreateNoWindow = true;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C \"c:\Program Files (x86)\TekRADIUS LT\trclilt.exe\" -u " + username + " " + password;
process.StartInfo = startInfo;
process.Start();
string line = "";
while (!process.StandardError.EndOfStream)
{
    line = line + "\n" + process.StandardError.ReadLine();
}
File.WriteAllText(HttpContext.Current.Server.MapPath("~\error.txt"), line);

TekRadius 在直接通过 CLI 或 GUI 或通过 Visual Studio 的内部服务器执行时工作正常。但是在主服务器上，我的自定义错误日志 error.txt 显示此错误：

TekRadius CLI 使用 SQLLite 来存储其用户名和密码。我知道是 TekRadius 无法访问 'C:\Windows\TEMP\System.Data.SQLite.dll'，而不是我的应用程序，因为我使用的是 SQL 服务器，而且我上面的 C# 代码没有尝试访问数据库。我正在使用 Windows Server 2012 R2，我也无法在 Windows 文件夹上设置新权限。请告诉我如何才能允许 TekRadius CLI 访问此位置？

Answer 1

终于在12小时后我自己解决了。解决方案是为 C:\Windows\Temp 文件夹中的 System.Data.SQLite.dll 完全控制 ISS_IUSRS。此外，对 c:\Program Files (x86)\TekRADIUS LT\trclilt.exe.
