Odd Issue With Bound Columns When Fetching Data.

I'm using ODBC 3.0 in code written in C.

I have an service that connects using a system DSN using the SQL Server 2000 driver. On my development system with SQL Server 2005 Express installed, the queries work fine. I prepare a statement and then bind the columns that will be in the result set. On my system, I get all the data as it should be but on a live system, I do not get the proper data for the last three rows. I don't get any error messages from the query or the column binding and there are also no extra information messages that I can retrieve.

The table is something like the following. The names are changed to protect the guilty.

CREATE TABLE DOWNLOAD
(
FIELD_1 NUMERIC( 6,0 ),
ID CHAR( 15),
FNAME( 30 ),
LNAME( 40 ),
CLIENT_ID NUMERIC( 9,0),
CLIENT_NAME CHAR( 50 ),
CODE NUMERIC( 4,0 ),
PHONE CHAR( 10 )
)
go


On my system, running the exact same binary code as the client machine, I get all of the data from all of the columns as it should be. The problem is when I run on a client's system, the CLIENT_NAME, CODE, and PHONE columns return null values even when there is data there. On my development system the SQL Server instance runs on the same machine. On the client's sytem I am connecting to a remote instance of SQL Server 2000 on another system on the network.

My quandry is what could be different between the two systems that is causing me the problems?
