[Samba] Samba 3.0.21 and WinXPSP2 problems

Hi all,

I have a OpenBSD box running samba 3.0.21, it's configured to offer one  
publicly available share. The problem is that when i connect from WinXPSP2  
box and start browsing the share client hangs for ~5 mins without any  
success when tries to access any file. Browsing folders is ok and  
everything is 100% working for smbclient.

Here's my smb.conf:

[global]
         workgroup = YAVAM
         netbios name = GANDALF
         interfaces = 192.168.1.128/0
         log level = 3
         log file = /var/log/samba/%m.log
         max log size = 500
         max wins ttl = 30
         min wins ttl = 30
         os level = 65
         preferred master = Yes
         domain master = Yes
         local master = Yes
         wins support = Yes
         remote browse sync = 192.168.1.255
         map to guest = Bad User

[data]
         path = /var/archive
         read only = No
         guest ok = Yes
         force user = ikido
         force group = users

Here's smbd's log of an incoming connection:

It seems like Windows is just disconnecting when recieving part of a

Thanks in advance,
