MS Access 97 Database on 2003 Server

Recently I did migration from NT4 to 2003 Server. There are Access97 databases shared on this server. Since users running Access97 from thin terminals started to get error 3043: "disk or network error". The same error I got when try run from console NT4 terminal server. It's never happens from 98 or XP stations. All other applications are OK. Looks like nona seconds disconnactions which affect Access97 only cause this problem. Anybody knows how to fix this problem?
Thanks,
Alex.
