我写了一个访问MS SQL Server的C＃应用程序。我对应用程序的开发没有任何问题。我现在在部署阶段，一个奇怪的问题已经出现。该应用程序将通过终端服务向最终用户提供。由于某些原因，如果标准用户执行了应用程序，则该应用程序无法访问数据库，仅当用户是域管理安全组的成员时，它才能访问它。如果我为用户服务SQL Management Studio或使用ODBC DSN连接到数据库，则可以访问数据库。它似乎与.NET应用程序有关。我通过Citrix为应用程序提供服务，但也有一个2倍的环境，并且在两者中都有相同的问题。终端服务和.NET都必须是某种东西。
欢迎任何建议或人们在类似问题上的经验。
编辑：
这是我在用户不是域管理组成员

rhope问题在您的连接字符串中。可能是您正在连接字符串中使用集成安全选项。如果是 - 请将您的连接字符串更改为使用SQL Server授权的字符串。不要忘记将用户和用户映射添加到相应的数据库中。https://www.connectionstrings.com/
