samba - Jan 2004 - reseting conection

Hi list.

    I have a problem with samba and Windows stations.
    My Windows stations are losing conection with the server. I have 15 Windows
XP Professional and 1 Windows 98se.
    My samba logs:
    
    lib/util_sock.c:read_data(436)    
read_data: read failure for 4. Error = Connection reset by peer

    My samba is 2.2.7a-8.9.0 running in a RedHat 9.0 with mysql-3.23.58-1.9

Please help-me ;-)

Thank?s
