【问题描述】:
所以我今天在我公司的 ASP.net 网站(建立在旧的 DotNetNuke 框架上)出现错误,上面写着:
与 SQL Server 建立连接时出现与网络相关或特定于实例的错误。服务器未找到或无法访问。验证实例名称是否正确以及 SQL Server 是否配置为允许远程连接。 (提供者:命名管道提供者,错误:40 - 无法打开与 SQL Server 的连接)
这列出了这个堆栈:
[SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)]

DotNetNuke.Services.Log.EventLog.DBLoggingProvider.DBLoggingProvider.AddLog(LogInfo objLogInfo) +75
DotNetNuke.Services.Log.EventLog.LogController.AddLog(LogInfo objLogInfo) +175
我最近不得不关闭该站点,我只是将文件移动到硬盘驱动器的另一部分。当我把它们搬回来时,我得到了这个。它正在连接回我们拥有的单独服务器,但连接中的某处有一个块。两台机器都能够相互ping通,所以我猜这是服务器级别的东西?堆栈对我来说非常模糊,所以我不知道在哪里寻找我的错误。想法?
【问题讨论】:
-
1.您是否能够使用 sql server management studio 或使用应用程序服务器中的 odbcad32.exe 连接到数据库? 2.确保在有sql server的机器上——sql server agent服务正在运行
-
尝试让sql server配置服务停止启动。
