Samba was working, but prompts for log-in from Windows boxes now

Hi all,

On Slackware 10.0 I'm running Samba 3.0.4 and it was working perfectly
for several months until I tried to add a printer. Now it just
prompts for users to log-in with username/password, yet it never lets
them log-in no matter what is entered.

Here's what happened:

Via Webmin I added the network IP printer (HP Laserjet 5n) and all was
fine. I then went into the Samba config via webmin to add printer to
samba (first time to use Webmin with samba -- generally edit smb.conf
by hand). I messed around with the printer settings before deciding
to do it manually. I added the printer line and restarted samba.
That's it.

I rebooted and winbind and smbd are both running. I'll attach my
smb.conf and other files at end of this email. I know I'm still
connected fine to our Windows NT 4.0 domain because 'wbinfo -u',
'wbinfo -g', 'getent passwd', and 'getent group' all work fine and
show our domain users and groups with no problems.

When I try to browse to server from Windows 2000 Pro it says
'Incorrect password or unknown username for: \\linuxserver Connect As
.... Password ...'.

When I enter like DOMAIN+USERNAME with password it says Username
invalid but anything else says "The Credentials supplied conflict with
an existing set of credentials".

For my PC the log shows this:
[2004/11/05 15:14:18, 1] passdb/passdb.c:pdb_set_sam_sids(201)
NULL guest account!?!?
[2004/11/05 15:14:18, 0] auth/auth_util.c:make_server_info_info3(1120)
make_server_info_info3: pdb_init_sam failed!

Any ideas? HEre are the critical files:

/etc/nsswitch.conf:
passwd: files winbind
shadow: files
group: files winbind
hosts: files dns
#(all else is commented out)

/etc/samba/smb.conf:

[global]
log file = /var/log/samba/%m.log
guest account =
name resolve order = wins hosts lmhosts bcast
idmap gid = 10000-20000
socket options = SO_SNDBUF=16384 SO_RCVBUF=16384
wins server = 10.142.120.6
domain master = False
encrypt passwords = yes
public = yes
level2 oplocks = False
oplocks = False
netbios name = HOSER
write cache size = 8388608
server string = Samba Server
winbind enum users = yes
idmap uid = 10000-20000
password server = *
workgroup = HBMC
os level = 10
winbind enum groups = yes
security = domain
preferred master = no
winbind separator = +
log level = 1

I've given everything I can think of... and nothing has changed as far
as I know. I just stopped and restarted the server to add a freakin
printer. If anyone sees anything that could be screwing-up, I'd love
some feedback. The logs for the PC are the only thing that's changed,
but not sure what they mean.

Thanks in advanced for any suggestions or ideas...

You need a valid guest account. Take this line out. The default is nobody.
Or you can specify one if you don't want to use the nobody account. Use
guest account = ftp or some other account.
