In a DTS, in the Connection Properties, I select the "File DSN" radio button and select a DSN file. I click OK. I re-open the Connection to re-check the Connection Properties, and, instead of seeing the "File DSN" radio button selected with the file I selected, I see the "User/System DSN" radio button file, and "dBASE file" selected. The only work around I know of is to recreate the DTS, and to get the "File DSN" right the first time. Since this is a lot of work, I'm wondering---can I change it to "File DSN" and keep the change I've made?
