I think what is significant is that this server and the domain
controller are on separate TCP/IP subnets (which happen to be on
separate VLAN's.)
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
subnets.
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.

Hello,
I've a rhel6 server on a vmware structure.

Network:
IP=10.13.16.22 NETMASK=255.255.254.0
GATEWAY=10.13.16.1 (it is on a different vlan in rspect to the dc)
I successfully join the domain:
net join -w -S domaincontroller -U networkadmin
domaincontroller network:
IP= 10.13.0.49 NETMASK=255.255.252.0
GATEWAY=10.13.0.3
and all is running fine for a while. After some time I'm not able to have the
authentication to the DC:
net rpc testjoin
Unable to find a suitable server for domain
Join to domain '' is not valid: NT_STATUS_UNSUCCESSFUL
I've a dubt that with different vlan the DC and the samba server cannot
communicate, but I'm not sure and in which way bypass it.
Thank you
Kind Regards
Romano
