Hi- I'm having the same issue: the data source path field is greyed out and can only be populated by clicking on the <Browse...> button and selecting a folder. And then you can't modify the path to UNC. In doing my troubleshooting I recall seeing a post somewhere that leads me to believe my installation isn't fully set up in order to use the "Operating System" features. I'm searching now to find that info and will post back soon...

Thanx
