I am testing a connection using tnpsing. Unfortunately, the service

Here's one method to find just what files are being used by tnsping.
Get the windows equivalent of strace: http://www.howzatt.demon.co.u

Following is an example usage with tnsping:
X:\zips\Windows_Utilities\Tracing\NtTrace\NtTrace-x64\NtTrace>nttrace
tnsping js03 | find /i ".ora"
