# Change Domain Controler IP Address

First, modify `/etc/network/interfaces` and `/etc/hosts` files with the new IP.

If you have two or more domain controllers, modify `/etc/krb5.conf` file.

Check `/etc/resolv.conf` file if needed and the DNS forward set in `/etc/samba/smb.conf`.

Check if `/var/lib/samba/private/krb5.conf` is a symbolic link of `/etc/krb5.conf`.

Reboot the server. Samba will reconfigure him self with the new IP address.

You can check if DNS response are correct with the command :

    dig @localhost srvads.domain.lan
    dig @localhost domain.lan

Modify the reverse DNS if needed.
