Redundand DNS Server

hi,

i know solution have redundancy following setup:

 

windows server 1

ad / dhcp / dns / file server

 

windows server 2

redundand server failover server1.

 

server 1 set 192.168.0.1, clients connected using 192.168.0.1 primary dns. 

 

now question is, if server 1 fails, computers run slow , unresponsive primary dns dead.  server 2 needs set additional domain controller, dns?  how set dns redundand in case server 1 fails?  same question dhcp.

 

thanks in advance.

 

hello,

proceed that:

• promote second server additional dc
• install dns service on
• make gc server

after ad replication, dns ad-integrated zones replicated second dc. so, make sure domain zones ad integrated.

after make each dc points primary dns server , other 1 secondary one. also, configure client computers use second dc secondary dns server.

this ensure high-availability of ad/dns service , reduce risk of losing domain.

for dhcp, can use 50/50 dhcp rule (ip addresses assign divided on both dhcp servers. ensure high-availability of dhcp service , permit avoid conflits of ip addresses assigning.

note both dcs used authentication , ldap queries.
