# Create on-premises Data Source Name (DSN)

Create a Data Source name (DSN) on the external on-premises server where you installed the BIS Azure Relay Windows service.

> [!NOTE]
> **Note**
> 
> If you connect from D365 F&SCM on-premises to an external on-premises server, no Azure Relay is required. In this case, the Data Source Name (DSN) must be created on the D365 F&SCM server.

### Steps

1. In **Windows**, open the **Control Panel**.
2. Click **Administrative Tools**.
3. Double-click **ODBC Data Sources (64-bit)**.
