Verwenden von Process.Start () zum Starten eines Prozesses als anderer Benutzer innerhalb eines Windows-Dienstes

Ich scheine eine funktionierende Implementierung (Works On My Machine (TM)) für die folgenden Szenarien zu haben:

Batch-Datei, .NET Console Assembly, .NET Windows Forms-Anwendung.

Hier ist wie:

Ich habe einen Windows-Dienst, der als Administratorbenutzer ausgeführt wird. Ich füge dem Administratorbenutzer die folgenden Richtlinien hinzu:

• Melden Sie sich als Dienst an 
• Handeln Sie als Teil des Betriebssystems
• Passen Sie die Speicherkontingente für einen Prozess an 
• Ersetzen Sie ein Token auf Prozessebene

Diese Richtlinien können hinzugefügt werden, indem Sie Systemsteuerung/Verwaltung/Lokale Sicherheitsrichtlinie/Zuweisung von Benutzerrechten öffnen. Sobald sie festgelegt sind, werden die Richtlinien erst beim nächsten Anmelden wirksam. Sie können einen anderen Benutzer anstelle des Administrators verwenden, was die Sache ein bisschen sicherer macht :)

Jetzt verfügt mein Windows-Dienst über die erforderlichen Berechtigungen, um Jobs als andere Benutzer zu starten. Wenn ein Job gestartet werden muss, führt der Dienst eine separate Assembly ("Starter" .NET Console Assembly) aus, die den Prozess für mich initiiert.

Der folgende Code, der sich im Windows-Dienst befindet, führt meine Assembly "Starter" aus:

Process proc = null;
System.Diagnostics.ProcessStartInfo info;
string domain = string.IsNullOrEmpty(row.Domain) ? "." : row.Domain;
info = new ProcessStartInfo("Starter.exe");
info.Arguments = cmd + " " + domain + " " + username + " " + password + " " + args;
info.WorkingDirectory = Path.GetDirectoryName(cmd);
info.UseShellExecute = false;
info.RedirectStandardError = true;
info.RedirectStandardOutput = true;
proc = System.Diagnostics.Process.Start(info);

Die Konsolenbaugruppe startet dann den Zielprozess über Interop-Aufrufe:

Das grundlegende Verfahren ist:

1. Melden Sie den Benutzer an
2. wandelt das angegebene Token in ein primäres Token um
3. Führen Sie den Prozess mit diesem Token aus
4. Schließen Sie den Griff, wenn Sie fertig sind.

Dies ist der Entwicklungscode, der frisch von meiner Maschine stammt, und keinesfalls für den Einsatz in Produktionsumgebungen bereit. Der Code hier ist immer noch fehlerhaft - Für den Anfang: Ich bin nicht sicher, ob die Ziehpunkte an der richtigen Stelle geschlossen sind, und es gibt einige oben definierte Interop-Funktionen, die nicht erforderlich sind. Der separate Starterprozess nervt mich auch wirklich. Im Idealfall möchte ich, dass all diese Job-Artikel in einer Assembly verpackt sind und von unserer API sowie diesem Service verwendet werden. Wenn jemand hier Vorschläge hat, wäre er dankbar.
