[Samba] xp: unknown user name or bad password

[toddandmargo]

Hi All,

Fedora Core 26

# rpm -qa \*samba\*
samba-common-4.6.7-0.fc26.noarch
samba-common-libs-4.6.7-0.fc26.x86_64
samba-4.6.7-0.fc26.x86_64
samba-client-libs-4.6.7-0.fc26.x86_64
samba-winbind-modules-4.6.7-0.fc26.x86_64
samba-libs-4.6.7-0.fc26.x86_64
samba-client-4.6.7-0.fc26.x86_64
samba-common-tools-4.6.7-0.fc26.x86_64
samba-winbind-4.6.7-0.fc26.x86_64

I am replacing a CentOS 5 Samba Server with a Fedora 26 Samba server.

XP clients work fine with the CentSO5 server, but not the FC26 server.
And smbclient works fine from Linux.

>From XP, I get:
     net view \\FedoraServer
     System error 5 has occurred.   Access is denied.

     net use z: \\FedoraServer\public xxxxxxx /USER:todd
     System error 1326 has occurred
     Logon failure: unknown user name or bad password.


On the Linux side, both of these work perfectly:
     smbclient -L=192.168.xxx.12
     smbclient -L 192.168.xxx.12 -U todd


What am I doing wrong?  I have attached  my error smb.conf
without the shares to save space.

Many thanks,
-T
