问题所在平台：Windows XP SP3 / Lotus Notes 7.0
问题内容：
因工作需要，我需要使用几个远程数据库，我的操作步骤如下：
1、从File -> Database -> Open打开"Open Database"对话框后，在"Server"一栏输入远程数据库所在服务器的地址，点击"Open"按钮，一阵搜索过后，弹出提示"Unable to find path to server. To trace this connection, use File - Preferences - User Preferences - Ports - Trace (Notes client) or Trace Command (Domino server)"
2、依照提示，进入File - Preferences - User Preferences - Ports - Trace对话框，在"Destination"一栏中输入远程数据库所在服务器的地址，点击"Trace"，依旧弹出步骤1中的无法找到服务器提示，将Trace信息Copy下来，如下(因工作保密需要，服务器名及地址不便公开，用*号代替)：
