Additionally, verify that any firewall or network security configurations allow the communication between the machines. The login is from an untrusted domain and cannot be used with Windows authentication.

Check firewall and network settings: Make sure that the necessary network ports (e.g., TCP port 1433 for default SQL Server instances) are open and accessible between the Mac1 machine and the SQL Server machine (Mac2).

Ensure that you are specifying the correct server name, instance name, and authentication method (e.g., 'Server=Mac2 Database=YourDatabase User Id=YourUsername Password=YourPassword').

Verify connection settings: Double-check the connection settings in your connection string or connection configuration.

Restart the SQL Server service to apply the changes.Īfter making this change, you should be able to connect to the SQL Server using SQL Server Authentication credentials from Mac1.

Select 'SQL Server and Windows Authentication mode.'.Right-click on the server name and select 'Properties.'.Open SQL Server Management Studio (SSMS) on the SQL Server machine (Mac2).This will allow you to authenticate using SQL Server credentials (username and password) rather than relying on the Windows domain authentication. Use SQL Server Authentication: If you are unable to establish a trust relationship between the domains, you can switch to SQL Server Authentication instead of Integrated Authentication.Contact your system administrator to establish the necessary trust relationship between the domains. If the domains are in different forests or there is no trust relationship established, you may encounter this error. Ensure trust between domains: Verify that the domain Mac1 and Mac2 belong to is trusted by the SQL Server domain.

Try the following steps to resolve this issue: The error message you receive indicates that SQL Server is configured to use Integrated Authentication (Windows Authentication), but the login is being attempted from a domain that SQL Server does not trust.
