我的網站是在舊主機工作完美無瑕，但現在我搬到了一個新主機的連接已成功與服務器建立的，但後來發生了錯誤 - provider：TCP提供程序，error：0

請注意：的舊主機是VPS上同一主機

所以我停止支付他和現在我主機上相同的主機作爲共享主機。

所以我感動了所有的文件到根文件夾，並在Web.config文件

我不能加載網站由於某種原因，配置的SQL細節。我總是得到錯誤。 請幫助我！

後，我固定我的Ajax問題。這裏 - >Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0 Error

我遇到了另一個問題..

這是我的SQL Server詳細信息：

Server name : WEBSQL2K5

Server version : Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)

Standard Edition on Windows NT 5.2 (Build 3790: Service Pack 2)

myLittleAdmin (for SQL Server and MSDE) v.2.7 r.118

這是連接字符串

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

它報告一個無效的網絡名稱，但我沒有看到它將在哪裏指定。它是否在另一個缺失的配置文件中設置？（是'localhost'嗎？似乎不太可能，但你永遠不知道，你的主機上的'localhost'是否正確解析？） – sarnold

嗯..我不認爲有另一個配置文件。它是一個共享主機..即使我將其更改爲127.0.0.1它仍然顯示我相同的錯誤 – Ofear

同樣你要問你的供應商與username和password創建MS-SQL database或者您可以通過控制面板中創建它。

他們已經這樣做。我有DBname和數據庫usr和密碼。並將所有SQL表設置爲 – Ofear

@Ofear - 然後使用當前數據庫server.set DataSet = WEBSQL2K5構建連接字符串的更多信息，請訪問：http://www.connectionstrings.com/ – adatapost

您的知識是驚人的！！這樣可行！非常感謝你！！ – Ofear

我有這個問題。

發生這是因爲數據庫服務器已被賦予第二個IP地址。在客戶端，這個名字可以解決哪個地址非常有用，而且我正在獲得新的地址。

刪除第二個IP地址解決了問題。

我懷疑SQL服務器正在監聽原始地址，但不在附加的地址上。

這聽起來是我所擁有的，因爲我一直都沒有看到這個錯誤。您是否從SQL Server網絡配置中刪除IP地址？ – H20rider

我知道這已經回答了，這些解決方案可能也有效，但我遇到了這個問題，經過幾個小時的嘗試從網絡上提出不同的建議 - 一件事情奏效了。

重置我的Web應用程序使用的IIS應用程序池。

有時回到基礎幫助！

在我的情況下，「TCP提供程序，錯誤：0 - 指定的網絡名稱不再可用。」錯誤是由網絡安全設備造成的。一旦源自此服務器的數據庫連接被排除在安全監控之外，則此問題已解決。

我想補充一點，如果您的系統使用的是* .ini文件，您可能想要檢查那裏輸入的服務器名稱，並確保它與web.config連接字符串中的內容相同。

我也有類似的問題，但不完全一樣：

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.)

我跟着@Password在重新啓動應用程序池，但後來看了高級設置，看到「啓用32位應用程序」被設置爲假。我改變了這個是真的，我的問題解決了。希望這可以幫助那些嘗試過所有其他建議並打破僵局的人。

的連接已成功與服務器建立的，但後來發生了錯誤 - provider：TCP提供程序，error：0
