A. 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 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
