I have a server (Physical) that has been promoted to  a Domain controller.
I have a DHCP server running on it and DNS server also.
(I have an exchange 2013 server box too).

In order to have a backup I created another server and also made it a domain controller.
it is working fine. I checked the logs and everything seems fine.
I also configured DNS on that server and it is playing nice with the other DNS server on my 'primary' domain controller.

as for the DHCP i used the option of 2012R2 that has the load balancing.
there also it is working fine.

my problem is the following :
As far as I know the FSMO roles can leave (each one) on 1 server only.
If my assumption is right then if I have a problem with my primary server (DC) then reverting to the second DC (if the first one is dead) will not make me run 100% without issues.
is that statement correct ?

what I am trying to say is what are the settings/measures I should be taking so that my 2 servers (DC1 and DC2) can be replaceable (meaning I m 100% functional if one is down forecefully).

I am sure that it is possible. It is just me that doesnt have the knowledge. That is why I come back to you gurus !!
