samba - Aug 2004 - TR : Connection Issue - Samba 3.0.2a Solaris 6 - NT4 SP 6

Hi all,

First, here is a small description of our environnement :
We have a PDC running a domain. let's call this server pdc01. All of our
users are defined in the domain.
We have a Unix server hosting a database. Let's call this server unix01. All
users can access this server and use the database. They are allowed of
generating report which are stored in their home directory on unix01. 
Unix01, and pdc01 are on different network with a firewall between them.

I would like to configure samba to act as a Domain member, and have users
accessing their home directory on unix01 through a share. We also have
unix02 and unix03 working the same way. SAMBA is working well on unix02 and
unix03 but I cannot get unix01 to work.

When I try to join the domain, this is what I get (these are the last line
of command net join rpc -d10) :

Earlier on in this output, I see Samba trying to broadcast queries on
network 10.xx.xx.255 (which is unix01 net). pdc01 is on a different network.
Do I have to configure something ?

Do you have any idea of what is going on ? 
Thanks a lot in advance.
