To troubleshoot, check if SQL Server Authentication is enabled. You can do this through SQL Server Management Studio (SSMS) by right-clicking on the server, selecting 'Properties', and navigating to the 'Security' page. Ensure 'SQL Server and Windows Authentication mode' is selected. If not, change the setting, restart the SQL Server service, and attempt the login again.
