[Samba] Access via IP but netbios name

[steven.TSE]

Hi,
 
I have successfully connected to win2000 domain with Samba3.01 on RH9.
Kerbero version is 1.27.  Win98 and ME user can connect to the share folder
with both netbios name and IP address of samba.  However, win2000 and XP can
only connect with IP address but netbios name.  The log.winXP shows "failed
to verfiy incoming ticket".  Is there anything wrong?  smb.conf as below:
 
=====
# Global parameters
[global]
 netbios name = fileserver
 realm = PEH.COM
 security = ADS
 auth methods = winbind
 password server = pdc
 client lanman auth = No
 client plaintext auth = No
 log file = /var/log/samba/log.%m
 min protocol = LANMAN1
 local master = No
 # ldap ssl = no
 idmap uid = 10000-20000
 idmap gid = 10000-20000
 template homedir = /home/winnt/%D/%U
 template shell = /bin/bash
 winbind separator = +
 wins server = 192.168.0.9 192.168.0.55
