[Samba] can't mount smb shares

[Valéry Roché]

Hi list,

it's me again. I have 2 samba servers, one as a PDC, the other as a file 
server.
I can now join the domain. But it's impossible to mount the smb shares.

The 2 servers are listening on several private networks, using vlans. 
10.16.41.0/24 is a routed network, all over the campus. The others are 
just nated through a FreeBSD box.
All dns datas are ok and uptodate

If I connect from a box on the 10.16.40.0/24 network, everything is ok, 
I can mount the shares on the file server. But if I connect from a box 
on 192.168.x.y networks, I don't mount the shares, sometimes don't mount 
the home, and it seems that the netlogon script is not executed. I make 
an automatic copy of the netlogon script in the user home ; if i execute 
it, i have this error : "network path not found" (or something like 
that, don't know how to translate it from french).

The problem is, I think, that in the logon script, I refer to monoxyde's 
shares as \\monoxyde\some_share. But this server is known as monoxyde 
only on the 10.16.41.0/24 network. On other networks, it's known 
differently on the dns.
This morning, if i execute the logon script by hand, i can mount all the 
shares, but it's not executed at logon time.

If the workstation is configured with dhcp, the connexion to the domain 
is erratic (domain unknown) ; i must reboot the workstation for a good 
login on the domain.

I think the problem is a network browsing problem, isn't it ? But i 
don't find any solution.

If anybody has an idea... I'm desperate, please help.

I pasted the global sections of the 2 smb.conf.

Thanks for reading this,
Valéry Roché
