我试过的事情：

• sql server / window身份验证的不同登录凭据..
• 清理temp中的所有缓存 安装了mvc 3和4

仍然安装程序说上面的错误给出错误

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

我用谷歌搜索，但无法找到关于sitecore的相关信息......请建议

Answer 1

您需要禁用SQL Server命名管道并通过协议，只需启用TCP / IP。

从这个链接 - http://sdn.sitecore.net/Products/Sitecore%20V5/Sitecore%20CMS%205,-d-,3/Installation/Troubleshooting.aspx得到了这个

思考 - 可能是第一次使用命名管道尝试并失败，但如果它被禁用，它肯定会使用TCP连接，这应该可以解决问题。

Answer 2

你能检查一下sql server是否设置为“windows authentification only”模式，这可能是造成这个问题的原因。如果是这样，您需要将其更改为“SQL Server和Windows身份验证模式”，请参阅此link以获取帮助

Answer 3

这似乎是一个SQL连接字符串问题，与sitecore无关。检查您的connectionstrings.config以查看您是使用集成安全性（Windows）还是在连接字符串中传递用户凭据。
