XP and Samba.....again

["schmity" <schmity@nctv.com>]

Newbie here.   I have a home network with a XP machine and a Debian
machine connected through a router.  I have not set Static IP's on
either machine.  I am trying to connect these machines with samba, and
I have made a simple smb.conf file as follows:

#######################################
[global]
       # Server configuration paramaters
       netbios name = LINUXBOX
       server string = Samba %v on (%L)
       workgroup = SANDSTORM
       encrypt passwords = yes

[data]
       path = /export/samba/data
       comment = Data Drive
       volume = Sample-drive
       guest ok = yes

[test]
       comment = TEsting
       path = /export/samba/test
       read only = no
       guest ok = yes
####################################

Also from the command line I did

########################################
Linuxbox:/home/brent# smbpasswd brent
New SMB password:
Retype new SMB password:
Linuxbox:/home/brent# cat /etc/samba/smbpasswd
brent:1000:874EA23DF4AFD3CFC2265B23734E0DAC:153EDE431C871577C60F69CAD6DF1601:[U
        ]:LCT-45895F8A:
Linuxbox:/home/brent#
Linuxbox:/home/brent# ls -l /etc/samba/smbpasswd
-rw-------  1 root root 105 2006-12-20 10:06 /etc/samba/smbpasswd
##############################################

and an smbclient -U% -L localhost returns the following:

######################################
Linuxbox:/home/brent# smbclient -U% -L localhost

I can see LINUXBOX on the XP machine.  When I double click on
"Linuxbox" on the XP machine it prompts me for a username and password.
 I fill in the appropriate username and password hit enter, and it
prompts me again for the username and password except that in username
it has BLACKBOX\brent filled in (Blackbox is the name of the XP machine
and "brent" is the username).  I am using the same username and
password for Samba, the Debian logon, and the XP logon.
