How to set Static/DHCP IP Address from command line

In Windows Server 2008 Core installation, the only way to setup IP Address eithe Static or DHCP is from the command line. The following procedure helps setting the IP Address from the command Line using “netsh”. This procedure works in Windows Server 2008 (No core installation as well), Windows Server 2003, Windows XP, Windows Vista.
To setup Static IP Address:
From the command prompt:
1. Type 
C:\Users\Administrator> netsh interface ipv4 show interfaces
Idx  Met   MTU   State        Name
—  —  —–  ———–  ——————-
  1   50 4294967295  connected    Loopback Pseudo-Interface 1
 10   20   1500  connected    Local Area Connection
This should show the Network Connections. We are looking for the name here. On mine, I have one LAN interface and is named as “Local Area Connection”
2. To set a static IP Address type the following command
C:\Users\Administrator>netsh interface ipv4 set address name=”Local Area Connect
ion” source=static address=192.168.0.5 mask=255.255.255.0 gateway=192.168.0.1
The syntax is
netsh interface ipv4 set address name=”” source=static address= mask= gateway=
Where:
ID is the name of the LAN Connection
StaticIP is the static IP address that you are setting
SubnetMask is the subnet mask for the IP address
DefaultGateway is the default gateway
3. Now set the DNS Servers one at a time with the followind command. For each DNS server, increase the index number.
C:\Users\Administrator>netsh interface ipv4 add dnsserver name=”Local Area Conne
ction” address=192.168.0.1 index=1
C:\Users\Administrator>netsh interface ipv4 add dnsserver name=”Local Area Conne
ction” address=192.168.0.10 index=2
The syntax is
netsh interface ipv4 add dnsserver name=”” address=index=1
Where:
ID is the name of the Network Connection
DNSIP is the IP address of your DNS server
This should do. To confirm, do an “ipconfig”
Ethernet adapter Local Area Connection:
   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Broadcom 440x 10/100 Integrated Controller
   Physical Address. . . . . . . . . : 00-1D-09-D4-2C-8F
   DHCP Enabled. . . . . . . . . . . : No
   Autoconfiguration Enabled . . . . : Yes
   IPv4 Address. . . . . . . . . . . : 192.168.0.5(Preferred)
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.0.1
   DNS Servers . . . . . . . . . . . : 192.168.0.1
                                       192.168.0.10
                                       127.0.0.1
   NetBIOS over Tcpip. . . . . . . . : Enabled
Set IP through DHCP Server
To set the DHCP Server, from the command line
C:\Users\Administrator> netsh interface ipv4 set address name=”Local Area Connection” source=dhcp
Syntax is
netsh interface ipv4 set address name=”ID” source=dhcp
where ID is the name of the Network Connection
