Моему приложению C # не удается подключиться к моему экземпляру SQLServerExpress.
Запуск приложения с использованием localhost\SQLExpress или <servername>\SQLExpress в строке подключения работает локально на сервере, но не с других хостов в сети.
- Я уже добавил правило брандмауэра для порта
1433.
AllowRemoteConnection установлен на true.
Я все еще получаю SqlException поговорку:
System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

Что еще мне нужно проверить?
