Hi Claude,

Thank you for your advice. We didn’t have _IWAM user. But after we added it, it didn’t help. We are missing something else.

Let me tell you more about what we came across solving this problem.
Foxpro table My.dbf and DLL that is trying to update it are sitting on the same web server (only in different directories).
We decided instead of ASPNET account create a user MyUser, who will have all rights to DLL and DBF directories.
During testing, I logged in to the server as MyUser (mapped the server to F:) and opened My.dbf exclusively:
USE f:\data\My.dbf IN 0 EXCLUS && OK
I can browse, but can’t type in anything. In modify structure window it shows as (Read Only).
If I do exactly the same not remotely from my PC, but going to the server from Remote Desktop and run Foxpro on the server. Then the table can be opened with no Read Only, and there is no problem to update it.

I hope it might give you better picture to understand the problem we have.

Thanks,
Galina
