I have disabled DHCP on the modem what is next please help...
The server will need to be a domain controller. http://www.windowsreference.com/dns/...-server-setup/
On the clients ip is assigned automatically as well as dns... Is this right?
Yes only if a DC is created
Do i need to disable dns on the router as well?
The server will have dhcp and dns enabled so turned off on the router
The switch connects to the the router and all the PCs are connecte to the switch.
