Microsoft JET Databse Engine Error Message

Hi,
When I try to import DBF files into the SQL Server,
I got the following error messages for some files.

Error Source: Microsoft JET Databse Engine
Error Destination: External table is not in the expected
format
Context: Error calling OpenRowset on the provider.

Does anyone know about this error?

I found that only files that have *.FPT (memo) files didn't work
and other files were imported successfully/

I installed sql server service pack and I checked that
the machine has the latest JET Database engine (4.0).

I'm using Microsoft SQL Server 2000 Standard Edition
w/ Service Pack 2 & Microsoft FoxPro 2.6.

Thank you in advance.

- Hyung -Did anyone ever answer this?sql
