FileUpload works fine, but uploaded files have restricted access

Hi,
I'm using the asp FileUpload control, which uploads the files just fine. However, once the file is in the system (say a pdf) it can't be accessed from the web... I check the file security and access to the file is restricted. But no folder that it's in is denying access to web users.. So how can I stop this auto-deny-access from happening?
