Dos Application on Win XP

An app that works on a Win95 Peer to Peer Network refuses to run on a WinXP connection. The software was installed on a new WinXP PC, then the directory was shared. Still a Peer to Peer network.

All clients now give the following error : Error DBFNTX/1001 OPEN ERROR: PASS.DBF (DOS ERROR 5).

When the host is a Win 95 PC, no problem. PASS.DBF is a file from the app installation. Further errors are : ERROR DBCMD/2001 WORKAREA NOT IN USE: ORDLISTCLE, and ERROR BASE/1002 ALIAS DOES NOT EXIST:PASS.

I wonder if it is a WinXP issue?

Any help mose welcome. I thank you in advance for your thoughts.
