[Samba] after joining the domain the server loose the domain controller

I think what is significant is that this server and the domain
controller are on separate TCP/IP subnets (which happen to be on
When you do your initial domain join, you specify the name of the domain
controller- that name probably resolved via DNS (or may be from
/etc/hosts) so all goes well, even though the machines are on different
My guess is that when your machine authenticates to the domain
controller the next time around it is "asking" for a domain controller
but not explicitly asking for the same controller it used before. So
it might be doing a broadcast, which will not be successful. You need
to make sure your member server "knows" about machines on the DC's subnet.
1- Configure your DC as a WINS server. Configure your member server as
a WINS client.
2. Configure "remote browse sync" with the member server querying the
DC for its browser info.
3. Use lmhosts on your member server - similar to the hosts file,
except that it also tells you which machines are DC's for the domain.
