I'm doing an integration on a client and they have OracleDB (this is like working for the devil ) and I got this error.

What I did?

Provide the ASPNET, IUSR_MACHINENAME and IWAM_MACHINENAME, Read & Execute, List Folder Contents, and Read permissions accounts to the ora92 (Oracle installation) directory and all sub-directories and files. (An ASP.NET account will be created and added to your users list when you install the .NET framework). You must restart your machine for the permission changes to take effect.

Magic happens Oracly!
