If anyone can help me out I would greatly appreciate it.
The short of it is that a once working group of client computers (Windows 98, NT, & XP) logged onto a Samba domain, now after the server crashed, they can't join the domain. I've tried joining them to a workgroup, then joining the domain and the error basicly says "can't find user or you do not have permission to join this domain". Strangly, if the XP machines join a workgroup, then log in using the Samba user name and password, they can get to their shares. The users are set up in Red Hat and in Samba. The share permissions are correct. The system is Red Hat ES running Samba 3.0. Here is the smb.conf:

#======================= Global Settings =====================================

# workgroup = NT-Domain-Name or Workgroup-Name
workgroup = X

# server string is the equivalent of the NT Description field
server string = server

# This option is important for security. It allows you to restrict # connections to machines which are on your local network. The # following example restricts access to two C class networks and # the "loopback" interface. For more examples of the syntax see # the smb.conf man page
hosts allow = 127.0.0.

# if you want to automatically load your printer list rather # than setting them up individually then you'll need this
# printcap name = lpstat
# load printers = yes

# It should not be necessary to spell out the print system type unless # yours is non-standard. Currently supported print systems include:
# bsd, sysv, plp, lprng, aix, hpux, qnx
printing = cups

# Uncomment this if you want a guest account, you must add this to /etc/passwd # otherwise the user "nobody" is used

# this tells Samba to use a separate log file for each machine # that connects
log file = /var/log/samba/%m.log

# Put a capping on the size of the log files (in Kb).
max log size = 500

# Security mode. Most people will want user level security. See # security_level.txt for details.
# Use password server option only with security = server
; password server = <NT-Server-Name>

# Password Level allows matching of _n_ characters of the password for # all combinations of upper and lower case.
; password level = 8
; username level = 8

# You may wish to use password encryption. Please read # ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents ;
smb passwd file = /etc/samba/smbpasswd

# The following are needed to allow password changing from Windows to # update the Linux system password also.
# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
# the encrypted SMB passwords. They allow the
Unix password
# to be kept in sync with the SMB password.
; unix password sync = Yes
; passwd program = /usr/bin/passwd %u
; passwd chat = *New*UNIX*password* %nn
*ReType*new*UNIX*password* %nn

# Using the following line enables you to customise your configuration # on a per machine basis. The %m gets replaced with the netbios name # of the machine that is connecting
; include = /etc/samba/smb.conf.%m

# Most people will find that this option gives better performance.
# See speed.txt and the manual pages for details
socket options = TCP_NODELAY SO_RCVBUF=8192

# Configure Samba to use multiple interfaces # If you have multiple network interfaces then you must list them # here. See the man page for details.
# interfaces =

# set local master to no if you don't want Samba to become a master # browser on your network. Otherwise the normal election rules apply
local master = yes

# OS Level determines the precedence of this server in master browser # elections. The default value should be reasonable
os level = 150
# log level = 2

# Domain Master specifies Samba to be the Domain Master Browser. This # allows Samba to collate browse lists between subnets. Don't use this # if you already have a Windows NT domain controller doing this job
domain master = yes

# Preferred Master causes Samba to force a local browser election on startup # and gives it a slightly higher chance of winning the election
preferred master = yes

# Enable this if you want Samba to be a domain logon server for # Windows95 workstations.

"host" means use the unix

"host" therefore is system configuration # dependant. This parameter is most often of use to prevent DNS lookups # in order to resolve NetBIOS names to IP Addresses.
Use with care!
# The example below excludes use of name resolution for machines that are NOT # on the local network segment # - OR - are not deliberately to be known via lmhosts or via WINS.
name resolve order = wins bcast lmhosts

# WINS Proxy - Tells Samba to answer name resolution queries on # behalf of a non WINS capable client, for this to work there must be
# at least one WINS Server on the network. The default
is NO.
; wins proxy = yes

There is no other domain controller on the network.
The Red Hat log is filling up with smb errors stating that each workstation is attempting to log on but "no computer account exists"

If someone could point me in the right direction on this I would be very greatful.

Ok, I was able to streamline the smb.conf file to look like this:
workgroup = x
netbios name = server
passdb backend = smbpasswd
printcap name = cups
add user script = /usr/sbin/useradd -m %u delete user script = /usr/sbin/userdel -r %u add group script = /usr/sbin/groupadd %g delete group script = /usr/sbin/gruopdel %g add user to group script = /usr/sbin/usermod -G %g %u add machine script = /usr/sbin/useradd -s /bin/false -d /dev/null %u logon script = login.bat logon drive = h:
logon path = \%LProfiles%U
wins support = yes
domain logons = Yes
os level = 35
preferred master = Yes
domain master = Yes
idmap uid = 15000-20000
idmap gid = 15000-20000
printing = cups
dns proxy = no
remote announce =
hosts allow = 192.168.4. 127.0.0.

#============================ Share Definitions ==============================

comment = Home Directories
valid users = %S
read only = No
browseable = No
# nt acl support = no
path = /home/%U
create mask = 0755

comment = Network Logon Service
path = /home/netlogon
admin users = root
guest ok = Yes
browseable = No

It seems that the old "take your working smb.conf file with you" method does not apply to the newest releases of Samba. The more streamlined the file the better it works. There seem to be some additional lines that are needed also. smile.gif

I had a problem kind of like this at home (only I used a XP and 2000 machine). smile.gif

So only the XP computer can join the domain?

Are you sure that you've allowed the other comptuers access?
To allow a workstation access to the domain (computer name "MACHINE"):

useradd MACHINE$ -s /bin/bash
(if this doesn't work, try "userdel MACHINE$ && useradd MACHINE$ -s /bin/bash -m"
smbpasswd -a -m MACHINE

If the password is not automatically added, you must use the machine name - without $ - in small letters (useradd machine -s /bin/bash). Just like above, if it still doesn't work after you've added machine, try "userdel machine && useradd machine -s /bin/bash -m"

Then on the NT workstation, in the network properties, change the domain name and then you should receive the message "Welcome to the domain".

If you havn't already, here is what you change in the 95/98 or NT registry (thanks to the guides section, nifty stuff that)

For Windows 95/98
Using the registry editor (regedit), create the registry setting
Add a new DWORD value:
Value Name: EnablePlainTextPassword Data: 0x01. (just enter --> 01)

Windows NT

Using the registry editor (regedit), create the registry setting
Add a new DWORD value:
Value Name: EnablePlainTextPassword Data: 0x01 (just enter --> 01)

Please tell me if this works, I'd love to acually help someone else for a change. XD Sorry, I've never used windows98 with this, so I don't know if the above would work for it. *shrugs*

Found some sites that might help:

With the changes in the smb.conf file I was able to get all users and machines connected (Win 9X, NT, 2000 & XP) I didnt have to add anything to the above file but I did have to configure Dynamic DNS along side the DHCP services for computer browsing functionality. That was an entirely new fight. The network is, however, up and running like a champ. Not a Microsoft server in sight smile.gif

Thanks for the input.

This site was an amazing help:

Thanks again.
