# Microsoft RDP-Lizenzierungsprotokollfehler

Fehler des Microsoft RDP-Lizenzierungsprotokolls in Remote Desktop Manager werden behoben, indem der Konfigurationsordner zurückgesetzt, die RDP-Engine gewechselt oder die NLA-Einstellungen angepasst

Wenn Sie sich mit einer Remote-Arbeitsstation verbinden, erhalten Sie einen der unten aufgeführten Fehler.

```
The remote computer disconnected the session because of an error in the licensing protocol.
Please try connecting to the remote computer again or contact your server administrator.
```

```
The remote session was disconnected because license store creation failed with access denied.
Please run remote desktop client with elevated privileges.
```

### Lösung 1

1. Schließen Sie Remote Desktop Manager.
2. Navigieren Sie zu **%localappdata%\Devolutions**.
3. Verschieben Sie den Ordner **RemoteDesktopManager** auf Ihren Desktop.
4. Starten Sie Remote Desktop Manager neu.

### Lösung 2

Ändern Sie in ***Datei – Einstellungen – Typen – RDP*** die RDP-Engine auf ***RDP (FreeRDP Latest)***.

### Lösung 3

Versuchen Sie, die Option ***NLA*** unter der Registerkarte ***Verbindung*** in den ***Eigenschaften*** der Sitzung zu aktivieren/deaktivieren.

### Lösung 4

In einigen Fällen und manchmal abhängig vom Host-Betriebssystem kann die Einstellung ***CredSSP*** störend wirken. Ändern Sie ihren Wert in der Registerkarte ***Sitzungseigenschaften – Allgemein – Erweitert***.

### Lösung 5

Versuchen Sie, die Option ***Konsole öffnen*** in den ***Allgemein***-Einstellungen der ***Eigenschaften*** zu aktivieren/deaktivieren, und prüfen Sie, ob die Fehlermeldung verschwindet oder unverändert bleibt.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/rdm/de/knowledge-base/troubleshooting-articles/microsoft-rdp-licensing-protocol-error.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
