running with NT4 workstation and my linux server is a Slackware 8.0 with
kernel 2.4.18 and Samba 2.2.4 running on a Pentium 166 MMX / 128 RAM / U160
40Gb SCSI disk.

share drive ) and at the same time loading big *.PDF files ( 15 Mb ) but it
doesn't work for a long time. After a few minutes, connection breaks and all
my file windows applications are not responding any more. So I have to wait
a few minutes before I can restore my share connections.
