# No se puede conectar al workspace

Al intentar conectarse a un espacio de trabajo de Microsoft SQL Server en Remote Desktop Manager, puede que aparezca este mensaje de error:

`A connection was successfully established with the server, but then an error occurred during the pre-login handshake.`

Es probable que su SQL Server esté configurado con un certificado autofirmado que no tiene en su almacén de certificados.

### Solución

Añada el certificado a su almacén o configure Remote Desktop Manager para que confíe en el certificado. Siga los pasos a continuación para la configuración de Remote Desktop Manager:

1. Seleccione su espacio de trabajo en el ***panel de navegación***.
2. Vaya a ***Archivo – Espacios de trabajo*** y, a continuación, haga clic en ***Editar espacio de trabajo***.
3. En la pestaña ***Avanzado***, haga clic en ***Más configuraciones***.

## 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/es/knowledge-base/troubleshooting-articles/unable-to-connect-to-the-workspace.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.
