在 IIS 6 中发布 Web 应用程序后,出现以下错误
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. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
它在具有相同数据库连接的开发服务器中运行良好
请帮我
