Problem accessing ntfs partition in FC4 samba server from XP

[Barry Yu <barryyupuilee@xxxxxxxxxxxxx>]

From a remote XP machine, I can access the fat32 partition in FC4 samba 
server, but when accessing ntfs partition in same FC4 machine, access 
being denied - No permssion for access indicated  (ntfs rpm package 
installed into kernel already and in FC4 locally can read files in this 
ntfs partition).
The /etc/samba/smb.conf is as below;

[global]
security = share

[FAT32]
comment=Fat 32 data
path=/mnt/f32
read only=no
public=yes

[NTFS]
comment=NTFS data
path=/mnt/ntfs
read only=yes
public=yes

Have I missed any thing?
