Add DNS to Subscriber and IM12.5

[Juraj Papic]

Hello,

I have to add DNS to my subscriber and IM, will this have any impact and I have to restart any services?

thanks.

If I remember correctly it would result in a restart of the network, with a small dip in communication, but not resulting in any real disruption to services.

Have a look on below document.

Hello,

The pdf is talking about the DNS name I just want to change the IP address for the Primary and Secondary.  The name will be the same, should I reboot the hold cluster?

thanks.

You don’t have to restart the cluster.

Hello Roger,

THanks in advance.

If all you want to do is to change DNS servers you don’t need to restart any service or server.
