无法启动SQL Server

Question

我正在为学校项目制作网站。已下载的Visual Studio 2010（我们在学校中使用的版本），现在我试图在上面运行我的网站。 SQL不会连接。我尝试了我所知道的一切，没有任何成效 当试图在SQL Server Management Studio中连接时，它会给我的用户“登录失败”。顺便说一句，我正在尝试Windows身份验证试图看着SQL错误日志，并没有任何！

我越来越沮丧，我在网上看到的每个回答都提到了真实的网站和我不明白的术语。我只是想让我的数据库工作！请帮助。

不知道该怎么做。

编辑：好吧找到了日志！这是在一个文件夹有点不同，然后提到。 我认为这是问题： 编辑：尝试了几个建议的步骤。服务器现在（我认为）处于单用户模式。 仍然无法登录，但不同的问题 - 这是日志。

Answer 1

那么，在安装Microsoft SQL Server之后，您需要重新启动PC，然后确保它已正确添加到Windows服务中。尝试运行“services.msc”并找到Microsoft SQL Server服务，检查状态以及是否被禁用 - >启动它。

Answer 2

尝试使用SqlConnection使用sql connection string连接到SQL。通常比其他方法效果更好。

Answer 3

也许你的sql服务器服务没有启动。试试这个...

去：控制面板 - >管理工具 - >服务

检查这些服务是否已启动：

1. SQL全文筛选器守护程序启动（MSSQLSERVER）
2. 的SQL Server（MSSQLSERVER）
3. SQL Server集成服务10.0
4. SQL Server报表服务（MSSQLSERVER ）
5. SQL Server VSS编写

 
after check that all, launch SQL Server Management Studio . 

you may connect to your server now with click on connect button: 
(server type: database engine, server name:. and authentication:windows authentication) 

in object explorer on left side by default you should see your server, if not, try click on "connect object explorer" then click on connect button.

我是可怕的延时抱歉，因为我现在看到您的评论。我只是想，也许你有另一个使用你的MS SQL服务器端口的程序。例如ms sql server使用端口80，另一个程序/服务器如apache使用相同的端口。 如果每一个都在Windows登录/启动时开始启动，则第一个程序将使用该端口，因此不允许其他端口使用该端口。 so！？如果您的问题仍然存在，您必须检查80端口是否未被其他程序使用。
