One Domain for 3 networks

hello guys, i've been looking best solution , i'd opinion.

today scenario basically;

3 networks different domains (w2k3);

192.168.0.x/24

192.168.2.x/24

192.168.3.x/24

i can connect in network from/to direction.

my idea deploy new dcs (w2k8) in 192.168.0.x network , "duplicate" other ones. 

dc 0:

192.168.0.1/24

192.168.0.254 gw

dns 192.168.0.1

dc 2:

192.168.2.1/24

192.168.2.254 gw

dns 192.168.2.1

dns 192.168.0.1

dc 3:

192.168.3.1/24

192.168.3.254 gw

dns 192.168.3.1

dns 192.168.0.1

can guys see mistake?

i first recommend making dcs dns , gc servers high-availability of ad / dns services , minimize risk of losing ad domains.

i recommend making adjustments on dns configuration. recommend following:

dc 0:

192.168.0.1/24

192.168.0.254 gw

dns 192.168.2.1

192.168.3.1

192.168.0.1

dc 2:

192.168.2.1/24

192.168.2.254 gw

dns 192.168.2.1

dns 192.168.0.1

192.168.3.1

192.168.2.1

dc 3:

192.168.3.1/24

192.168.3.254 gw

dns 192.168.3.1

dns 192.168.0.1

192.168.2.1

192.168.3.1

that, if 1 dcs fail, other ones able dns resolution no issues.
