permissions problem

[BillE]

I am using VS2006 VB.NET webforms.

I have a folder in my project where PDF files are created when data is
exported. The export works fine on my development machine.

I give write permissions to the folder to the IIS_WPG group on the
production server after I publish the site, but the permissions are reset
each time I publish the site. Otherwise permission is denied for creating
the PDF files.

Is there a way to prevent the permissions on the export folder being reset
when I publish the web site?

Thanks
Bill
