ODBC Errors after XP Conversion

[Ted Jenkins]

I am attempting to convert An Access97 application to XP
that uses one .mdb for forms, queries, etc., another for
database, plus accesses tables on an AS/400 via ODBC.
After running the conversion, I am able to access the .mdb
data, but not the AS/400 data (neither in application or
in development mode). I get 'ODBC - connection to AS400-
DSN failed. (Error 3151)'

I've tried several times to recreate new DSN with various
parms, but can't get around this.

Any help?

Thanks,
Ted
