samba错误

snow123456

我做出的samba怎么会出现对一台计算机有限制的呢？？？一台计算机只能打开一个文档，若是多打开，就不可以，这是什么原因呢？？
我的smb.conf是这样配置的
[global]
workgroup = Network
server string = Project-file
security = user
null passwords = yes
map to guest = Bad Password
encrypt passwords = yes
smb passwd file = /usr/local/samba/private/smbpasswd
stat cache size = 128
getwd cache = yes
deadtime = 1
protocol = NT1
netbios name = project-file
socket options = TCP_NODELAY SO_RCVBUF=32768 SO_SNDBUF=32768
read size = 32768
os level = 30
auto services = global
host msdfs = yes
