==Definition:==
The DHCP (Dynamic Host Configuration Protocol) tells the hosts IP addresses. It operates on the principle ROSA (Request Offer Selection Acknowledgment). It applies to the IP from a so-called IP address pool. Windows 2003 Server includes defaultly a DHCP server. The DHCP- Server will arrange IP addresses to the clients, but they will defautly exist 8 days, then you will need a new address. After the PC gets a new address. This process is called leasing. After the 4 days the host will ask the DHCP server if he is available. Similarly, after seven days. If the DHCP server on the 8th day is still not reachable, the host loses the IP address and gets the IP 0.0.0.0. Therefore, always 2 DHCP server row.
