# Errore del protocollo di licenza di Microsoft RDP

Gli errori del protocollo di licenza RDP di Microsoft in Remote Desktop Manager si risolvono reimpostando la cartella di configurazione, cambiando motore RDP o modificando le impostazioni NLA.

Quando si connette a una workstation remota, riceve uno degli errori seguenti.

```
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.
```

### Soluzione 1

1. Chiuda Remote Desktop Manager.
2. Vada a **%localappdata%\Devolutions**.
3. Sposti la cartella **RemoteDesktopManager** sul desktop.
4. Riavvii Remote Desktop Manager.

### Soluzione 2

In ***File – Impostazioni – Tipi – RDP*** cambi il motore RDP in ***RDP (FreeRDP Latest)***.

### Soluzione 3

Provi a selezionare/deselezionare l'opzione ***NLA*** che si trova nella scheda ***Connessione*** nelle ***Proprietà*** della sessione.

### Soluzione 4

In alcuni casi, e talvolta a seconda del sistema operativo host, l'impostazione ***CredSSP*** può interferire. Ne modifichi il valore nella scheda ***Proprietà della sessione – Generale – Avanzate***.

### Soluzione 5

Provi a selezionare/deselezionare l'opzione ***Apri console*** e verifichi se il messaggio di errore scompare o rimane invariato nelle impostazioni ***Generale*** delle ***Proprietà***.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation 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/it/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 `automate deployments from our CI pipeline` 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.
