The error message is pretty clear: 错误消息非常清楚：
Cannot open database "GroupALD" requested by the login.
Login failed for user 'lester\\les' .
Your user doesn't have a valid login on your new database - it's not a connection-string related issue - you need to create a login for lester\\les on your new server and create a user in the GroupALD database for that login. 您的用户在新数据库上没有有效登录 - 这不是与连接字符串相关的问题 - 您需要在新服务器上为lester\\les创建登录，并在GroupALD数据库中为该登录创建用户。

Can you connect to your express edition using SQL Server Management Studio of R2 ? 您可以使用R2的SQL Server Management Studio连接到您的快速版吗？
One workaround i can suggest is to export the database from express to R2 if you can connect to R2 using your connection string . 我建议的一种解决方法是，如果可以使用连接字符串连接到R2，则将数据库从express导出到R2。
