如何解决此问题？尝试确保用户可以访问连接字符串中的初始目录。如果您的连接字符串没有初始目录，请添加一个用户有权访问的目录。这可以解释为什么它在一种情况下有效，而在另一种情况下无效。您是否检查了您在windows服务中传递的密码是否与登录management studio时传递的密码完全相同？是的，我使用app.config的副本/粘贴登录。可能需要共享您用于连接的代码。还要说明此sql身份验证还是windows身份验证？错误中提到的数据库就是您尝试连接的数据库。还要确保您连接到了正确的服务器，等等。sql auth:current配置：
Data Source=s-vtgn02\prdsbvt04；初始目录=sttcoletorsbvt；用户ID=usr\u stt\u colator；密码=数据源=s-vtgn02\prdsbvt04；初始目录=sttcoletorsbvt；用户ID=usr\u stt\u colator；密码=
