Do not have a clue and without more information I doubt it is solvable.

So:

1) What application are using?

2) What are you doing when you use SQLGetInfo()?
     The code that you are using would be helpful.

3) You mentioned something about a trace. Is there information available
from that trace?

4) If not can you set up a trace?

5) Have you set up logging in ODBC?
    If so what is in the logs?
    If not set it up and then run the code.
