I am setting up a new domain controller in an office.

Can somebody please confirm the correct settings. I believe it is the following.

For server:

192.168.0.25
255.255.255.0
192.168.0.1

primary dns: 192.168.0.25
secondary dns: 192.168.0.1

work stations:

192.168.0.X
255.255.255.0
192.168.0.1

primary dns: 192.168.0.25
secondary dns: 192.168.0.1

DHCP is setup on router no the windows 2012 server - that how I want it.

Are these setting correct? Please assist

Those settings are technically sound; are you having issues using that network configuration?

im actually replacing a windows 2003 server. The previous IT guy had these settings:

server:

server ip: 10.0.0.1
subnet: 255.0.0.0
default gateway: 10.0.0.2
primary dns : 10.0.0.2
secondary dns: 8.8.8.8

workstation:

ip: 10.0.0.14
subnet: 255.0.0.0
default gateway: 10.0.0.2
DNS servers: 10.0.0.1
Primary WINS server: 10.0.0.2

DHCP is setup on the router- so the workstation receive network settings dynamically. The funny thing is WINS is not installed on the windows 2003 server so why is the ipconfig /all on the workstation showing Primary WINS server as being 10.0.0.2.  The funny thing is these settings are working, but how? Are they correct?

If the settings you just posted are working, then the network configuration you're looking to move towards will not work without making changes on the rest of the environment.  A couple things to keep in mind:

192.168.x.x will not work if the gateway is still 10.0.0.2, are you planning on changing the gateway to a 192.168.0.x address as well?

If WINS is not in use then there shouldn't be any issue removing it from the settings.

The environment is currently a /8, that seems a bit extreme for a single office.  If you stay with the 10.x.x.x subnet I would recommend subnetting further, going with a /16 (10.0.x.x) or even a /24 if you can get away with 254 IPs.  

Is the current 2003 server a domain controller as well?  You'll want to ensure you cleanly move roles (if they exist) to the new server and make necessary changes to AD sites and services if the IP schema changes to 192.x.x.x.

Unless 192.168.0.1 is a device that can handle DNS, there should be no mention of it anywhere.

Also, a domain controller sometimes runs into issues when a second DNS server is at play. Get rid of the second entry.

Is the router configured for your proposed subnet?
