Since you are presenting a SELECT statement I will assume you are trying to update a Table contained within your windows form and not a database table.
I really don't have an answer to this since there is nothing profound in the SELECT statement or in your description that points to a problem. Since, I assume, you are working with a windows application do both machines have the most updated version of the application? Are you silently handling errors which may be covering up the problem? (By silently I mean using a Try Catch block where the catch block is empty thus your error is never dealt with).
Very strange indeed.
