Windows Server 2003 and Windows XP provide the Netsh utility, which, among its many capabilities, can configure the IP properties of NICs. To set a static IP address, use this format:
netsh interface ip set address local static <IP address>
<subnet mask> <gateway> <metric of gateway>
as in the following example:
netsh interface ip set address local static 192.168.1.15
255.255.255.0 192.168.1.1 1
(Some command lines wrap to two lines here because of space constraints.)
To set a client's NIC DNS settings, run this command:
netsh interface ip set dns local static 192.168.1.150
primary
To set a client back to DHCP, run these commands:
netsh interface ip set address local source=dhcp
netsh interface ip set dns local source=dhcp
