我已经完成了几个建议创建用户/分配权限/更改连接字符串等的帖子，但到目前为止还没有任何帮助。任何帮助表示赞赏。

只需浏览一下您可以在此处执行的检查列表：

检查登录是否正常。因此，您可以使用＆sc;＃sc;＆＃39;登录SQL Management Studio。用户？
检查问题不是特定于此用户的。连接字符串是否与另一个用户一起工作，并且只有“sc＆＃39;用户？
如果任何用户失败，我们可以假设问题不在于登录，而在另一个地方可能是代码尝试连接，IIS配置，Windows防火墙或SQL Server。也许查看应用程序池或服务器协议配置。

此外，错误代码为3005（ErrorHttpAttemptConnect）说明＆＃39;由于网络错误而无法尝试连接＆＃39;。所以也许尝试增加连接超时。

最后，我会说在线检查常见的连接问题。这可能是一个好的开始：http://social.technet.microsoft.com/wiki/contents/articles/2102.how-to-troubleshoot-connecting-to-the-sql-server-database-engine.aspx

即使之后用户'sc'登录失败
