C# App not working in Windows 2000

I have an application written in C# using Microsoft Visual Studio 2005 Professional Edition Version 8.0.50727.762 (SP.050727-7600) AND Microsft .NET Framework Version 2.0.50727 SP1.

The app works on all the XP and Vista Machines but not on the 2000 Machines. Unfortunately upgrading the OS is not an option right now.
============
Microsoft Windows 2000
5.00.2195
Service Pack 4
============

When starting the application it prompts the user to scan there user id. On Return button click I get this error: (SEE Attached Text file "DEBUG.txt").

I can see that there is a problem where the app tries to access the database. (SEE Coded text below for my ODBC connection).

Are there any specific configurations that must be setup for the 2000 Machines?

Thanks any help here would be appreciated.
