Description:DHCP(Dynamic Host Configuration Protocol) is used to store network configuration at a central place (DHCP Server). The DHCP client will automatically contact the DHCP server (Port 67) and acquire what network configuration it should use.
- Client IP-Address
- Gateway IP-Address
- Primary & Secondary DNS Server IP-Addresses
Note if the client is configured in the network properties to acquire its TCPIP configuration through TCPIP, and there is no DHCP-Server available to serve an IP-Address to the client, then the client will block while timing out.
Note if the DHCP Client service is disabled or cannot find a DHCP server (not able to ping, broken TCPIP stack), then the command "ipconfig /renew" will give the following error message:

- Automatic, if using dynamic IP and on network with a DHCP server (Ex. Dialup user).
- Disabled, if using a static IP (And the computer doesn't need to register its hostname in DNS).
