DHCP Client

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 computer is part of a domain and dynamic DNS (DDNS) is used, then one should be aware that the DHCP Client is also responsible for registering the computer in the DNS.

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:

An error has occurred while renewing interface Local Area Connection. The RPC server is unavailable.
