[Samba] Vista password being rejected on share security mode

[Lee Devlin]

I'm working on trying to get Samba 3.0.23c to work with Vista and I've run into a snag.  If a share is set up for security = share, and protected with a password, when I try to mount the share using Start->Run->\\server\share,  the password is rejected by Samba for about the first 10 seconds, but after that, it lets me in.  I've tried all the common suggestions such as changing NTLMV2 on the Vista system without success.

I've looked high and low on the Internet and have not found a mention of this problem.  The smb.conf file looks like this:

[global]
netbios name = TestSystem
server string = "TestSystem"
workgroup = MSHOME
security = share
guest account = guest
log file = /var/log/samba.log
socket options = TCP_NODELAY SO_RCVBUF=65536 SO_SNDBUF=65536
encrypt passwords = yes
use spnego = no
client use spnego = no
host msdfs = no
interfaces = lo eth0 eth1 eth2 br0
qos enable = no
level1 file extensions = 
level2 file extensions = 
os level = 20
preferred master = auto
domain master = auto
local master = yes
domain logons = no
log level = 0
max log size = 960
null passwords = yes
wins server = (ip addresses deleted)
passdb backend = smbpasswd:/tmp/smbpasswd
use client driver = yes
printer admin = root, guest
show add printer wizard = yes
load printers = yes
default devmode = yes
printcap name = /tmp/etc/printcap
[printers]
comment = All Printers
path=/shares/Volume1/__var/spool/samba
printing = brcm
guest ok = yes
printable = yes
browseable = no
print command = chmod 666 %s; printcmd jobsubmit %p '%J' %x '%u'
lpq command = printcmd queuestat %p
lprm command = printcmd jobcancel %p %j
lppause command = printcmd jobpause %p %j
lpresume command = printcmd jobresume %p %j
queuepause command = printcmd queuepause %p
queueresume command = printcmd queueresume %p

[FileShare]
comment = 
path = /shares/Volume1/FileShare
writeable = yes
browsable = yes
inherit permissions = yes
inherit acls = yes
msdfs root = no
valid users = %S
user = %S
guest ok = no
guest only = no


...

Any suggestions?  

Thanks,
