Question

我正在为一个学校项目建立一个网站。下载Visual Studio 2010（我们在学校的版本），现在我正在尝试运行我的网站。 SQL将无法连接。我尝试了我所知道的一切，没有任何作用尝试在SQL Server Management Studio中连接时，它为我的用户提供了“登录失败”。顺便说一句，我正在尝试Windows身份验证尝试查看SQL错误日志，并没有任何！

我变得非常沮丧，我在网上看到的每个答案都提到了真实的网站和我不理解的术语。我只是想让我的数据库工作！请帮助。

不知道该怎么做。

编辑：好的，发现了日志！它在一个文件夹中有点不同，然后提到。我认为这是问题所在：编辑：尝试了几个步骤建议。现在（我认为）服务器处于单用户模式。仍然无法登录但不同的问题 - 这是日志。

Answer 1

也许你的sql server服务没有启动。试试这个......

转到：控制面板 - ＆gt;管理工具 - ＆gt;服务

检查这些服务是否已启动：

SQL全文过滤器守护程序启动器（MSSQLSERVER）
SQL Server（MSSQLSERVER）
SQL Server Integration Services 10.0
SQL Server Reporting Services（MSSQLSERVER）
SQL Server VSS Writer

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.

我很抱歉可怕的延迟，因为我现在看到你的评论。我想，也许你有另一个程序使用你的ms sql服务器端口。例如ms sql server使用端口80和另一个程序/服务器如apache使用相同的端口。如果每个人都开始在Windows登录/启动时提前启动，则第一个程序会占用该端口，因此不允许其他人使用该端口。所以！？如果您的问题仍然存在，您必须检查80端口是否被其他程序使用。

Answer 2

好了，在安装了Microsoft SQL Server之后，需要重新启动PC，然后确保将其正确添加到Windows服务中。尝试运行“services.msc”并找到Microsoft SQL Server服务，检查状态以及是否已经完成 - ＆gt;开始吧。

Answer 3

尝试使用SqlConnection使用sql connection string连接到sql。通常比其他方法更好。

无法启动SQL Server
