# No se puede conectar al espacio de trabajo

Solucione el error de protocolo de enlace previo al inicio de sesión de SQL Server en Remote Desktop Manager confiando en el certificado autofirmado o añadiéndolo a su almacén.

Al intentar conectarse a un espacio de trabajo de Microsoft SQL Server en Remote Desktop Manager, es posible 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 que se indican 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 haga clic en ***Editar espacio de trabajo***.
3. En la pestaña ***Avanzado***, haga clic en ***Más configuraciones***.
4. Desplácese hacia abajo hasta la configuración ***TrustServerCertificate*** y establezca su ***Valor*** en "true".
5. Haga clic en ***Aceptar*** en todas las ventanas para guardar los cambios y, a continuación, intente conectarse de nuevo.

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