Help :SQL error using Personal Netware

When using Delphi Verion 1, and running an executable on a PC under
Personal Netware the program falls over when trying to open an SQL
query.
The query is :

SELECT USERID, LASTNAME FROM 'USER.DBF' WHERE
GROUPID = :PARAMS[0]
ORDER BY USERID

PARAMS[0] is set to a string.

The error generated is :

'Not initialised for network files QA_0000'

It appears that the temporary table is begin created by cannot be read.

The program runs successfully on a stand alone machine and on a Novell
Network.

Any suggestions,
