Question

我的本地数据库连接几小时前工作正常。但现在我无法通过SSMS连接到本地数据库。我没有改变任何设置也没有改变。我正在使用SSMS的数据库，然后关闭我的笔记本电脑。现在我可以连接到它。

Component name                            Version
------------------------------------------------------
Microsoft SQL Server Management Studio    12.0.2254.0
Microsoft SQL Server 2014

我可以连接到不同服务器的其他数据库，但无法访问我的本地数据库。错误显示::
