sql-server – 尝试运行sqlcmd失败,无法建立连接？

HResult 0x2,Level 16,State 1
Named Pipes Provider: Could not open a connection to SQL Server [2].
Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : A network-related or in
stance-specific error has occurred while establishing a connection to SQL Server
. Server is not found or not accessible. Check if instance name is correct and i
f SQL Server is configured to allow remote connections. For more information see
SQL Server Books Online..
Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : Login timeout expired.

不知道为什么会这样？我可以从我的asp.net网站(在本地运行,如数据库)连接到sql server,但sqlcmd无法连接.

解决方法

>只有将服务器安装为默认实例时,您的命令才有效.>运行sp_helpserver以了解实例名称.
