My guess.

Different users. I'm pretty sure he ran that VB app as a desktop user with the standard set of superuser dev privs.

And I'm pretty sure that IIS on that same box is run in a guest account - or an account with minimal privs in order to secure the o/s as much as possible against hack attacks into the IIS server where the hacker gains access to the "processing space/environment" IIS runs in.

Do a desktop logon using the user account in which IIS runs. Check the registry entries (if you have access to it - if that IIS account is secure you should have minimal access to the registry). Determine what TNSNAMES file is used - and whether or not that file is readible from that user account.
