samba - Jul 2003 - Win XP Client Samba 2.2.3a cannot connect

I have the following smb.conf with samba 2.2.3a on debian 3.0:
 
    [global]
        encrypt passwords = yes
        security = share
    [pub]
        path = /home/samba
        writable = yes
        guest ok = yes
        guest only = yes

I've enabled the 'nobody' account in the smbpasswd file.
 
When I try to browse the available shares on the server from a Windows XP
client, I get numerous read errors in the smbd log file:
 
    [2003/07/14 22:06:09, 0] lib/util_sock.c:read_data(436)
      read_data: read failure for 4. Error = Connection reset by peer
 
Win XP just hangs for a few minutes and then eventually responds that I'm
unable to access the network resource.  However, I can successfully browse the
share from an openbsd machine using smbclient.
 
Does anyone know what's going on?  TIA!
