Process.Startを使用して別のプロセスを開始しようとしていますが、UACをオンにして別の資格情報で実行を開始します。次のエラーが発生します。
System.ComponentModel.Win32Exception:ログオンの失敗:ユーザーアカウントの制限。考えられる理由は、空白のパスワードが許可されていない、ログオン時間の制限、またはSystem.Diagnostics.Process.Start()のSystem.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)でポリシー制限が適用されていることです。
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)
UACをオフにすると、正常に機能します。ユーザー名とパスワードを指定せずにプロセスを開始すると、正常に機能します。以下はコードのコピーです:
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.Verb = "runas";
processInfo.FileName = command;
processInfo.Arguments = parameters;
processInfo.UserName = txtUserName.Text;
processInfo.Password = password;
processInfo.Domain = "myDomain";
processInfo.UseShellExecute = false;
processInfo.LoadUserProfile = true;
Process.Start(processInfo);
これはデスクトップセッションと関係があると思いますが、UACがオフのときになぜ機能するのかわかりません。
UACをオフにしたり、レジストリを変更したり、ローカル/グループポリシーを変更したりせずに、これを機能させる方法についてのアイデアをいただければ幸いです。
ありがとう

上記のコードを持つプロセスは、管理者として開始されます。
static void Main(string[] args)
{
//make sure we are running with admin privileges
if (VerifyIsAdmin())
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MyApp(args));
}
}
private static bool VerifyIsAdmin()
{
WindowsPrincipal principal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
bool isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
if (!isAdmin)
{
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.Verb = "runas";
processInfo.FileName = Application.ExecutablePath;
Process.Start(processInfo);
}
return isAdmin;
}

試しました CreateProcessWithLogonW ...同じ問題がありました。
さらに検索したところ、スマートカードログオン(scforceoption)を必要とするグループポリシーに問題があるようです。そうは言っても、UACがオフのときになぜそれが機能するのかはまだわかりません。ログオン時にスマートカードが必要です。
私はこれを回避することができるようには見えません。任意の洞察/アドバイスをいただければ幸いです。
次のことを行う必要があります:1。ログインしていて、このユーザーにアクティブデスクトップがあるユーザーを取得します2.このユーザーによって開始されたプロセスのハンドルを取得します3.このプロセスから資格情報を「盗みます」4.それらの資格情報を使用してプロセスを開始します
次のコードでうまくいくはずです。

以下のコードを使用した古いプロジェクトを見つけましたが、その時点で機能していました(あなたのプロジェクトと似ています)。おそらく役に立たないかもしれませんが、それでも試してみる価値はあります。
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.UseShellExecute = true;
startInfo.WorkingDirectory = Environment.CurrentDirectory;
startInfo.FileName = Application.ExecutablePath;
startInfo.Verb = "runas";
try
{
Process p = Process.Start(startInfo);
}
catch(System.ComponentModel.Win32Exception ex)
{
return;
}
この問題はあなただけではないようです。あなたがやろうとしているので、それは不可能かもしれません。
これは単なる推測ですが、管理者権限を要求してから ユーザーになりすます そして最後になりすまし中にプロセスを開始することができますか?
