Windows computer can't get IP address from DHCP

Suppose you configured a Windows computer to obtain IP address automatically via DHCP, but it doesn't work. Ipconfig shows that IP address is 0.0.0.0 and running ipconfig /renew returs errors like "Unknown interface" or "RPC server not available".

The most likely reason for this: DHCP Client service is not running. It is started automatically by default, but some users stop it, because it is not needed when you have a static IP address. Just start the service and ipconfig /renew should get you your IP address.
