[Samba] Cannot Map drive from XP to Samba shared folder

[Samantha]

Dear Sirs,

I have a Samba server with LDAP (in Fedora Core 4) and numbers of XP
client in a domain. After client login to domain, it runs a logon
script to map drive. Each client has own home directory in samba
server. Sometimes some of clients cannot map the drive to shared
folder in samba server after they login (At the same time, Some
clients can map the drive successfully)


My Samba version: 3.0.14a

smb.conf:

# Global parameters

[global]
unix charset = big5
dos charset= big5
  workgroup = GROUP1
netbios name = Server1
log level = 2

  security = user
  template shell = /bin/false
  winbind use default domain = no
  ldap passwd sync = Yes
  deadtime=15

[homes]
comment = Home Directories
valid users = %S
read only = No
browseable = No

[netlogon]
comment = Network Logon Service
path = /var/lib/samba/netlogon
guest ok = Yes
locking = No
browseable = No

[profiles]
comment = Profile Share
path = /var/lib/samba/profiles
writable = yes
create mask = 0600
directory mask = 0700
browseable = no
read only = No
profile acls = Yes

[Shared]
path = /Shared
writeable = no
valid users = @domain_administrators, @domain_users
browseable = no
read only = yes



The logon script:

net use y: /delete
net use y: \\Server1\Shared /persistent:no



In XP client, type "net use y: \\Server1\Shared /persistnet:no", it
prompts something like "Network Path was not found"



I'd be grateful if anyone knows what the problem is or has any ideas
how to solve such problem.

Thanks,
Samantha
