Configuring a new router in win 2003 dhcp server?

Hi, guys how are you doing?

I am working in a small company as network administrator. When I joined the company everything was configured by a former network administrator. Right now, I have some difficulties configuring a new Router in DHCP server. Let me explain it in detail.
Well, in this company there were not an internet connections until today but now the administration of the company bought a static DNS from ISP provider and said " you have to configure the Router to the DHCP server so that, all DHCP clients gonna have an internet connection because soon we will run web applications." right now, my problem is the DHCP server was not configured properly from the beginning because this server address (192.168.0.1) should be reserved for a Router address. please Take a look the configuration of the DHCP server

IP Address = 192.168.0.1
Sub net = 255.255.255.0
Gate way = no
DNS = 192.168.0.1

The Address pool is starting from 192.168.0.20 -192.168.0.254

right now, my question is what if i change the IP Adress of my domain controller from 192.168.0.1 to 192.168.0.2? and also changing the DHCP from the scope option the same address to the DC? then i will give this address 192.168.0.1 to the Router? just like this

IP Adress = 192.168.0.2
subnet = 255.255.255.0
g.way = 192.168.0.1
DNS = 192.168.0.2

please guys i need your help?
