# Errore di eccezione di violazione di accesso nelle sessioni RDP

Quando si tenta di aprire una voce di sessione RDP, potrebbe comparire il messaggio di errore "An unexpected error has occurred. Please check the application logs for more information." Controllando i log dell'applicazione, viene visualizzato il seguente errore: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

### Soluzione

Disabiliti l'API hooking RDP nelle impostazioni di Remote Desktop Manager:

1. Vada su ***File – Impostazioni – Tipi – Desktop remoto – API Hooking***.
2. Nell'elenco a discesa ***Abilita API hooking***, selezioni ***Disabilitato***.

## 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 current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/rdm/it/knowledge-base/troubleshooting-articles/access-violation-exception-error-in-rdp-sessions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
