我的网站在旧主机中运行完美,但现在我已移至新主机

请注意 旧主机 同一主机上 VPS

所以我停止付钱给他并且现在我在同一主机上托管共享主机

因此,我将所有文件移至根文件夹,并在 Web.config

中配置SQL详细信息

由于某种原因我无法加载网站。 我一直都有错误。 请帮助我!

我修复了我的Ajax问题..这里 - > Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0 Error

我遇到了另一个问题..

这是我的Sql Server详细信息:

  

服务器名称:WEBSQL2K5

     

服务器版本:Microsoft SQL Server 2005 - 9.00.4035.00(Intel X86)

     

Windows NT 5.2(Build 3790:Service Pack 2)上的标准版

     

myLittleAdmin(适用于SQL Server和MSDE)v.2.7 r.118

这是连接字符串

<connectionStrings>
        <add name="Con" connectionString="Data Source=localhost;Initial Catalog=DBname;user=DBusr;password=DBpass;" providerName="System.Data.SqlClient"/>
    </connectionStrings>

答案 0 :(得分:1)

您必须再次要求提供商使用MS-SQL databaseusername创建password,或者您可以通过控制面板创建{{1}}。

答案 1 :(得分:1)

我有这个问题。

发生这种情况是因为数据库服务器已获得第二个IP地址。在客户端上,关于名称解析的地址是幸运的,我得到了新的地址。

删除第二个IP地址解决了这个问题。

我怀疑SQL服务器正在侦听原始地址,而不是另外一个地址。

答案 2 :(得分:1)

我知道这已经得到了解答,这些解决方案可能也有效,但我遇到了这个问题,经过几个小时尝试来自网络的不同建议 - 有一件事有效。

  • 重置我的网络应用正在使用的IIS应用池。

有时回到基础有帮助!

答案 3 :(得分:1)

在我的情况下,&#34; TCP提供程序,错误:0 - 指定的网络名称不再可用。&#34;错误是由网络安全设备引起的。从安全监视中排除源自此服务器的数据库连接后,此问题已得到解决。

答案 4 :(得分:0)

我想添加一下,如果你在系统中使用* .ini文件,你可能想要查看那里输入的服务器名称,并确保它与你的内容相同。 web.config连接字符串。

答案 5 :(得分:0)

我有类似的问题,但不完全一样:

System.Data.SqlClient.SqlException (0x80131904): A connection was successfully established enter code here with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The specified data could not be decrypted.)

我在重新启动应用程序池时关注了@password,但随后查看了高级设置并看到了“启用32位应用程序”#39;设置为false。我将此更改为true,我的问题已解决。希望这可以帮助那些尝试过所有其他建议并走向死胡同的人。

答案 6 :(得分:0)

我遇到了这个问题,并且遇到了这篇文章,我想我会添加对我有用的解决方案,因为它没有列出。

更新System.Data.SqlClient nuget包解决了该错误。

答案 7 :(得分:0)

我遇到了同样的错误,但是通过通过SSMS进行连接时,通过显式选择“ TCP / IP”作为网络协议可以解决该问题

SSMS connection

答案 8 :(得分:0)

我在SSRS数据源上遇到了同样的问题,指向可用性组侦听器名称显示了相同的错误消息:

报表服务器无法使用您输入的信息连接到数据源。确保正确输入了连接字符串和所有凭据。
已成功与服务器建立连接,但是在登录前握手期间发生错误。 (提供者:TCP提供程序,错误:0-指定的网络名称不再可用。)

我的问题是只读路由URL配置。端点端口5022不起作用。当我使用默认端口时,数据源工作正常。

每个副本的URL配置应为(SECONDARY_ROLE(READ_ONLY_ROUTING_URL = N'TCP:// FQDN:1433')
