Network stucks at acquiring ip address in Windows XP

In Windows XP, Network does not acquire IP automatically and stucks forever at acquiring network address,

The possibilities are,

1. DHCP Service not running - Go to Start -> Run -> services.msc and start DHCP Client service and make it automatic.
2. Bad Network Cable - Replace Cable
3. Bad NIC Card - Service or Replace Network Card

that should do the trick !!!
