当我使用管理工作室访问数据库时，一切正常，我访问表......但是当我运行正在使用同一用户访问数据库的 Windows 服务时，会引发此错误。

Try ensuring that the user has access to the initial catalog in your connection string. If your connection string doesn't have an initial catalog, add one that the user has access to. This could explain why it works in one case and not the other.
