# Enable TCP/IP and open port 1433

This topic describes how to enable TCP/IP and open port 1433 so the RMH apps can communicate with SQL Server and synchronize data with the store database.

In most cases, Microsoft SQL Server will be running on a remote computer. You need to enable TCP/IP for the SQL Server instance and open port 1433 in the Windows firewall to allow the RMH apps to communicate with SQL Server.

{% hint style="warning" %}
This topic demonstrates how to enable TCP/IP in **SQL Server Configuration Manager** and how to open port 1433 in **Windows Defender Firewall**. It is provided as an example only. There are many ways to enable TCP/IP and open port 1433. Refer to the official Microsoft documentation for managing protocols and opening ports.

## 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.rmhpos.com/installation/install-microsoft-sql-server/installation-sql-server-tcpip-ports.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.
