Question

我正在使用别人的代码。试图解决它。我们重新映像了我们的服务器并上传了新的干净文件。（与以前的相同，只有这些没有被感染）我还恢复了我创建的数据库备份。

之前一切都有效，但现在我们遇到了问题。我没有使用此类身份验证的经验。在查询数据之前，它似乎通过了一个mdf文件。

似乎无法解决登录失败的用户错误。

Answer 1

ndt服务器登录不再存在，或者服务器登录不再与数据库用户（通常称为孤立用户）关联。

在第一种情况下，您需要创建数据库登录，然后处理孤立用户。

将数据库还原到新服务器或重建服务器或重新创建数据库登录时，会发生孤立用户。您可以在http://msdn.microsoft.com/en-us/library/ms175475.aspx找到有关解决此问题的说明。

用户'ndt'登录失败，请帮我解读堆栈跟踪
