[Samba] home share support problem samba

[Bill]

Hi, I am having a very difficult time mapping home directories with Windows
XP machines connecting to my samba 3 primary domain controller running on a
debian sarge machine.  The pdc works fine but the home directories of each
user refuse to mount and map as a network drive (i.e.. as Z:) .... here is
my smb.conf file....

[global]

   ;basic server settings
   workgroup = WORKGROUP
   netbios name = bill
   server string = Samba PDC running %v
   socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=8192 SO_RCVBUF=8192

   ;PDC and master browser settings
   os level = 64
   preferred master = yes
   local master = yes
   domain master = yes
   domain logons = yes

   ;security and logging settings
   security = user
   encrypt passwords = yes
   log file = /var/log/samba/log.%m
   log level = 2
   max log size = 50
   hosts allow = 127.0.0.1 192.168.1.0/255.255.255.0
   ;user profiles and home directory
   logon drive = z:
   logon home = \\%L\%U\
   logon path = \\%L\profiles\%U
   logon script = netlogon.bat

# ==== shares ====

[homes]
  comment = Home Directories
  browseable = yes
  writeable = yes
  guest ok = no
[profiles]
  path = /home/samba/profiles
  writeable = yes
  browseable = no
  create mask = 0600
  directory mask = 0700

[netlogon]
  comment = Network Logon Service
  path = /home/netlogon
  read only = yes
  browseable = no
  write list = admin

Thanks.
