[Samba] FC5. Samba 3.0.23a Win XP Pro SP2. Cannot logon from XP to samba on Fedora

[Clive at Rational]

Hello,

   I have just performed a yum update on my Fedora 5 machine, which I think included a samba update, and I cannot connect from WinXP to the shares defined on Fedora. When I select the samba server from WIndowsXP, a dialog box prompts for the userid and password. When userid and password are entered the dialog box just redisplays and I am not logged on, no matter how many time I try.

I have tried rolling back to samba 3.0.10 but there are too many dependencies of samba on other products to do that reliably.

I include below my yum.log messages, smb.conf file and the client.log messages

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba, 
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the 
# Samba-Guide which is generated daily and can be downloaded from: 
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash) 
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
