net ads dns register WARNING: no network interfaces found

Recently i got a requirement to change my MAC entry for a specific KVM host, since it's Virtual host MAC.
And the requirement also need to change the interface from eth0 to eth1


So after changing the MAC and interface name to eth1, everything went fine but i had a issue after few hours.
KVM host uses samba to register it's DNS entry into Active Directory, but it was failing somehow though it can join itself into AD but couldnot register it's IN A record into AD.

To fix it, check the two config files.

cybeerkeeda@Linux-Maniac:~ vim /etc/samba/smb.conf

And look for the below line , it must be look same 

interfaces = eth* bond* tun0 br0

cybeerkeeda@Linux-Maniac:~ vim /etc/samba/smb.sys

interfaces = eth*

Restart smb and all will work fine

cybeerkeeda@Linux-Maniac:~ service smb restart
