我从 vs2012 连接到远程 sql server 时遇到同样的问题
【问题讨论】：
-
您是如何尝试连接到远程 SQL Server 的？通过代码，还是 Management Studio？？
-
我可以通过 SQL SERVER Management Studio 快速连接到远程实例，但是当我尝试通过 Visual Studio 连接到它或使用 aspnet_regsql 时，它给了我上述错误
-
如果将连接字符串添加到web.config，然后通过代码建立连接呢？？
-
发现问题，是外部应用程序干扰连接造成的，“互联网下载管理器”，我卸载了应用程序，然后一切顺利。

@Mahdi：请将您的解决方案作为答案发布，以便其他面临相同问题的人快速看到可能的解决方案。理想情况下，还要说明您如何发现外部应用程序正在干扰。 （其他访问者可能不希望在 cmets 部分找到答案，因此永远看不到您的解决方案。）
