- Make sure the Database Server Windows Service is running by doing the following:
- Open the Windows Services list. To do so, on windows search type services and click on the Services or view local services result that appears.
- Search for the installed Database Server Windows Service. Its name should resemble this: 'SQL Server (SQLEXPRESS)'.
- Right click on it. If it is running, click on 'Restart'. If not, click on Properties, select as startup type 'Automatic', click on 'Start' and then 'OK'.
- If you want to connect to an existent database, make sure you have typed its name correctly- it is Case-Sensitive.
If you are attempting to connect using named instance name, please make sure that the Service SQL Server Browser for this instance is up and running. Also, be aware that using this method doesn't work for the default named SQL instances (MSSQLSERVER). - If nothing of the above works, try to do the same process with the option 'Encrypt database password' unticked and with your antivirus and Windows firewall disabled. If this solves the problem, contact your IT to configure your antivirus and network to allow the use of CostOS.
