I am trying to set up samba as primary domain controller and with home-shares (so that users gain access to their homes on a network-drive. My smb.conf is currently looking like this:

[global]

workgroup = fri-dom

server string = Samba Server
netbios name = smbserv

printcap name = /etc/printcap
load printers = yes

log file = /var/log/samba/%m.log

max log size = 50

security = user

encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd

unix password sync = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*UNIX*password* %nn *ReType*new*UNIX*password* %nn *passwd:*all*authentication*tokens*updated*successfully*

socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

domain master = yes

preferred master = yes

domain logons = yes

logon script = logon.bat

wins support = yes

dns proxy = no

idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
template shell = /bin/false
winbind use default domain = no
[homes]
comment = Home Directories
browseable = yes
writable = yes

[netlogon]
comment = Network Logon Service
path = /netlogon
guest ok = yes
writable = no
share modes = no

[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
guest ok = no
writable = no
printable = yes

---END---

Now, my problem is that when i try to configure the client to the domain "fri-dom", it prints that the domain does not exist. What could be my problem?

Are both your computers on the same subnet (the default (made up) ip address of windows computers seem to be 169.254.x.x while for linux, it is 192.168.x.x)? You should be able to ping
from each computer.

Is there a firewall blocking access to the ports that samba uses?

Yes they are on the same subnet, i can both ping and see the workgroup of the server on the client in the network neighborhood (i can't enter it though).

The firewall on the client is totally disabled, and there are no ports that have to be opened on the server are there?

We'll, I have a working SAMBA setup and here is the smb.conf:

[global]
workgroup = MSHOME
wins support = yes
encrypt passwords = yes
browsable = yes
security = share

[root]
path = /
read only = yes
guest ok = yes
public = yes

It's absolutely evil since it allows anyone to connect and shares /, but it works. Did
you have samba working before? If not, maybe try using my smb.conf. The complete
manuals to SAMBA are at www.faqs.org/docs/samba/ch00.html and in the /<prefix>/swat
dir if you built samba from the sources.

I do not have access to the server until tomorrow morning, i'll try your smb.conf then.
