What the hell does this error means, no body knows. After alot of googling and playing around on the server with IIS, I finally figured out the solution to my problem.
Because my web service application was using an older 32-bit Oracle driver, I had to force IIS7 to run in 32-bit mode and this is how I did it.
Under IIS7, my web application was running in an application pool.
- Right clicked over the AppPool name
- Selected Advanced Settings...
- Under the General Section, set Enable 32-Bits Application to True
- Click OK, you may want to recycle the application pool just to be sure.
