.net - 例外：System.Data.SqlClient.SqlInternalConnection.OnError中的.Net SqlClient数据提供程序（SqlException异常，

我正在使用安装程序进行sitecore 7.0安装...但每次在数据库设置时都会抛出相同的错误：

异常：.Net SqlClient数据提供程序

我试过的事情：

sql server / window authentication上的不同登录凭据..
清理temp中的所有缓存
- 已安装mvc 3和4

仍然是安装程序说错误上面有错误

尝试连接到SQL Server时出错：登录用户''失败了。有关详细信息，请参阅日志文件。

我用谷歌搜索，但找不到关于sitecore的相关信息...... 请建议
