Hello Friends,

We are trying to add a redundant domain controller to our existing domain.After creating additional domain controller ,i was unable to see it from the client when primary domain controller is down..

Make sure the appropriate entries for the new domain controller are in DNS.
If your primary domain controller is also the DNS server and it goes down, you're out of luck. So also install DNS on your second domain controller and point your clients to both of them

The replication of DNS will piggyback on top of AD and your DCs' will also host DNS, so you're killing two birds with one stone when your clients target the DCs' for login and DNS lookups. It's also the best way to go because since DNS is integrated with AD, it's secure and can't be corrupted by unauthorized zone transfers or those who don't have permissions to modify the zone file.
