Hi,Ruby MoshenkoWe cannot provide troubleshooting measures for your client software failure, I suggest you should investigate the basics of implementing a connection with the SQL Server instance.
- Make sure your server name is correct, e.g., no typo on the name.
- Make sure your instance name is correct and there is actually such an instance on your target machine. [Update: Some application converts \ to . If you are not sure about your application, please try both Server\Instance and Server\Instance in your connection string]
- Make sure the server machine is reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true).
- Make sure SQL Browser service is running on the server.
- If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.
