Final answer:
The feature that enables a Windows Server 2008 server with DHCP services to automatically detect and assign an IP address to a new workstation is Dynamic Host Configuration Protocol (DHCP). DHCP reduces administrative overhead and helps prevent IP conflicts by managing IP addresses dynamically.
Step-by-step explanation:
Dynamic Host Configuration Protocol (DHCP) is the feature that enables a Windows Server 2008 server with DHCP services to detect the presence of a new workstation and assign an IP address to that workstation.
When a new workstation connects to the network, it sends out a broadcast request for configuration information. The DHCP server receives this broadcast and responds with an IP address assignment, as well as other network configuration details such as the subnet mask, default gateway, and DNS servers.
DHCP is crucial because it simplifies the management of IP address allocation, effectively reducing the chance of IP conflicts and the administrative overhead associated with manual IP address assignment.
Without DHCP, administrators would have to manually configure IP settings for each new workstation on the network.
