[Samba] windows7 can not log on samba domain

[salih riza]

Hello All.

I have debian 5 samba file server and win clients. have problem with win 7
machines loging to samba domain.
 win xp machines can log on.

i implement this way http://wiki.samba.org/index.php/Windows7

but win7 gives error like "The specified account already exists".
i set up machine accounts on linux

useradd -d /dev/null -g 100 -s /bin/false win7$
and
smbpasswd -a win7$

and my smb.conf is below

what is wrong with me ? :(
