Samba 2.0.7 + FreeBSD 4.1-STABLE + W2k sp1

[Evpaty]

Hi all!
I have a FreeBSD 4.1-STABLE box as a file server. It has two NIC's

su-2.04# ifconfig
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 10.0.1.102 netmask 0xffffff00 broadcast 10.0.1.255
        inet6 fe80::250:baff:fed1:de26%rl0 prefixlen 64 scopeid 0x1
        ether 00:50:ba:d1:de:26
        media: autoselect (none) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UT
P <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 132.124.12.5 netmask 0xffffff00 broadcast 132.124.12.255
        inet6 fe80::210:5aff:fe46:db36%xl0 prefixlen 64 scopeid 0x2
        ether 00:10:5a:46:db:36
        media: 10base2/BNC
        supported media: 10base2/BNC 10base5/AUI 10baseT/UTP <full-duplex> 10bas
        eT/UTP <half-duplex> 10baseT/UTP

This is the Samba-2.0.7 config:

[global]
   workgroup = WKG
   server string = Samba Server
   hosts allow = 10.0.1. 132. 127.
   load printers = yes
   guest account = pcguest
   log file = /usr/local/samba/var/log.%m
   max log size = 50
   security = share
  encrypt passwords = yes
   socket options = TCP_NODELAY
   interfaces = 10.0.1.102/255.255.255.0 132.124.12.5/255.255.255.0
   local master = yes
   os level = 65
   domain master = yes
   preferred master = yes
   wins support = yes


One of them looks at the coaxial subnet, one - at 100Mbit UTP5
On the 100Mbit side of the router there is a Windows 2000 Box with 3Com 905B card. I have a problem with Samba from this box. Any operation 

like copying file to or from Samba share is done _extremely_ slow, 60-80 kb per second. This is not a network problem - ftp is 10 times 

faster. Windows 98 from the coaxial side of the router works much faster. How can i fix it?
