>Yes, the DBF resides in the same directory as the asmx file. When I look at the security for that directory, the one of the asmx file and the DBF file, I see the Everyone account with all the checkboxes in there. Does that mean that the IUSER account is having all those rights by default?

Something in the back of my brain is tickling me, saying that the Everyone group does not include anonymous (IUSER) accounts. I'm probably thinking of something else entirely, but you might want to add IUSER and see if that changes anything.

Also, do you know where VFP wants to put its temp files?
