为什么总是无法建立sql server database

Question

windows 7 + visual studio 2010,建立sql server database 时，总是提示“a network-related or instance-specific error occured 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: SQL Network Interfaces, error: 26-Error locating Server/Instance Specified)",我该怎么办呢，请大家帮帮忙，谢谢了！

Answer 1

程序组中看Sql Server的配置也中，服务和链接属性是否正确的配置了，SQL服务必须启动

Answer 2

看下sql服务是否启动 连接字符串是否有错误
