开启SMB后windows不可以访问ubunut，但反之可以

装的是ubuntu7.10，打开ＳＭＢ服务后ｗｉｎｄｏｗｓ的网上邻居可以看到ｕｂｕｎｔｕ上共享出来的盘符，但打开不了，说是没有权限，但在ｕｂｕｎｔｕ上可以用连接到服务器的方式连到ｗｉｎｄｏｗｓ上并读写，下面是我的ｓｍｂ。ｃｏｎｆ文件的部分信息，哪位大虾能帮我看下是哪里配错啦！！！
======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = workgroup
display charset = UTF-8
unix charset = UTF-8
dos charset = cp936

# server string is the equivalent of the NT Description field
server string = %h server (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
; wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
; wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses
; name resolve order = lmhosts host wins bcast

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = true
