In my experience, SQL Server Error 233 usually pops up because of login or network issues—like wrong authentication settings or disabled protocols.
You can try with below steps:
- Make sure SQL Server is using Mixed Mode Authentication.
- Check that TCP/IP is enabled in SQL Server Configuration Manager.
- Double-check your username and password.
- Make sure port 1433 is open in your firewall.
- Try restarting the SQL Server service.
But if you’ve tried all that and still can’t connect—especially if the database won’t attach or something doesn’t seem right—it could mean the database is corrupt. In that case, you can try using a tool like Stellar Repair for MS SQL to get the data back.
