1、报错信息描述 Named Pipes Provider: Could not open a connection to SQL Server [53]. 2、分析及解决 客户端是在尝试用named pipe方式访问数据库,需要用tcp的方式 先检查确认侦听的tcp端口,客户端上执行telnet ip port 确认连通性OK 客户端上CMD界面执行一下cliconfg,会弹出如下窗口 把TCP/IP加到启用列表中,然后应用并确定。...

SQL Server Named Pipes 是一种网络通信协议,它允许两台计算机之间通过命名管道进行数据传输。在 SQL Server 中,Named Pipes 是一种可选的客户端/服务器通信协议,与 TCP/IP 协议并列。它主要用于在同一台计算机上的客户端和服务器之间的通信,或者在防火墙配置较为严格的环境中,因为它通常不需要打开额外的端口。
在Microsoft SQL Server 配置管理器中,使用“Named Pipes 属性”对话框中的“协议”选项卡可以查看或修改默认管道的说明。 若要连接到其他管道,请在“默认管道”框中键入该管道。 有关连接字符串的详细信息,请参阅Creating a Valid Connection String Using Named Pipes。
Basically, this error message just tell you that the client cannot make a connection to the server. It's equvalent to "SQL Server does not exist or access denied" in MDAC. Although the error message say about Named Pipe Provider, the issue does not have to be...

PowerShell 没有直接的命令来创建命名管道,但可以通过调用 .NET 类库System.IO.Pipes.NamedPipeServerStream来实现创建命名管道。 权限设置: mkfifo可以在创建管道时直接设置文件权限。 PowerShell 需要依赖 NTFS 权限来控制管道文件的访问,或者通过编程手段对管道的读写权限进行控制。
(like CreatePipe for instance) returns the OS error 53. In most of the cases this is related to the network name resolution of the remote server or it might be permissions-related, e.g. if your current SQL Server instance is running under Local System account (which doesn't have network...
