[Samba] Problem with DNS configuration and "host" command . . .

I'm following the instructions here --

https://wiki.samba.org/index.php/Setup_a_Samba_Active_Directory_Domain_Controller

I've successfully "tested" my domain controller --

adam at eagle:~$ smbclient -L localhost -U%

adam at eagle:~$

Ubuntu "suggests" configuring a static ip in
'/etc/network/interfaces'
(instead of 'resolv.conf') --

adam at eagle:~$ cat /etc/network/interfaces

# The loopback network interface

iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
         address 192.168.121.149
         netmask 255.255.255.0
         gateway 192.168.121.1
         dns-search smbdomain.com
         dns-nameservers 192.168.121.149
adam at eagle:~$

Here's my 'smb.conf' (as provisioned, no edits) --

adam at eagle:~$ cat /etc/samba/smb.conf
# Global parameters
[global]
         workgroup = SMBDOMAIN
         realm = SMBDOMAIN.COM
         netbios name = EAGLE
         server role = active directory domain controller
         dns forwarder = 192.168.121.1
         idmap_ldb:use rfc2307 = yes

[netlogon]
         path = /var/lib/samba/sysvol/smbdomain.com/scripts
         read only = No

[sysvol]
         path = /var/lib/samba/sysvol
         read only = No
adam at eagle:~$

Any suggestions?  Thanks.

Don't believe Ubuntu :-D

Is this on the DC ? if so, can I suggest 'apt-get purge network-manager'

This will remove Network Manager (you don't need it on a machine with a 
fixed IP)
If resolvconf is installed, I would also remove this.

Set /etc/resolv.conf to point to itself:

search smbdomain.com
nameserver 127.0.0.1 # or you could use the DCs IP

Remove the 'dns' lines they do not really belong in this file.

See if this fixes your problem, if not report back.

I misunderstood the command --

adam at eagle:~$ host -t SRV _ldap._tcp.smbdomain.com.
_ldap._tcp.smbdomain.com has SRV record 0 100 389 eagle.smbdomain.com.
adam at eagle:~$

I arrived at the conclusion by following the instructions here --

https://wiki.samba.org/index.php/Testing_DNS_Name_Resolution

'network-manager' is not installed but 'resolvconf' is --

adam at eagle:~$ cat /etc/resolv.conf

resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

You'll see that I fixed the problem, and you'll see that in Ubuntu 
"dns-search" etc. worked.

Thanks for the suggestions.  You know how it is.  You work on a problem 
for awhile, and then you put it into words, and all of a sudden, the 
answer comes to you from some other source (as here)
