| 16. Service Name:-DHCPServer |

Description:-:The DHCP Server service allocates IP addresses and allows the advanced configuration of network settings such as DNS servers, WINS servers to DHCP clients automatically.
DHCP uses a client-server model. The network administrator establishes one or more DHCP servers that maintain TCP/IP configuration information and provide it to clients. The server database includes the following:
- Valid configuration parameters for all clients on the network.
- Valid IP addresses maintained in a pool for assignment to clients, plus reserved addresses for manual assignment.
- Duration of a lease offered by the server. The lease defines the length of time for which the assigned IP address can be used.
Dynamic Host Configuration Protocol (DHCP) is an IP standard designed to reduce the complexity of administering address configurations by using a server computer to centrally manage IP addresses and other related configuration details used on your network. The Windows Server family provides the DHCP service, which enables the server computer to perform as a DHCP server and configure DHCP-enabled client computers on your network as described in the current DHCP draft standard.
DHCP includes the Multicast Address Dynamic Client Assignment Protocol (MADCAP) which is used to perform multicast address allocation. When registered clients are dynamically assigned IP addresses through MADCAP, they can participate efficiently in the data stream process, such as for real-time video or audio network transmissions.
With a DHCP server installed and configured on your network, DHCP-enabled clients can obtain their IP address and related configuration parameters dynamically each time they start and join your network. DHCP servers provide this configuration in the form of an address-lease offer to requesting clients. With a DHCP server installed and configured on your network, DHCP-enabled clients can obtain their IP address and related configuration parameters dynamically each time they start and join your network. DHCP servers provide this configuration in the form of an address-lease offer to requesting clients.
If the DHCP Server service is stopped or disabled off, DHCP clients will not automatically receive IP addresses or network settings.

| 17. Service Name:-DFS |
| Executable Name:-dfssvc.exe |
| Log On As:-LocalSystem |
| Description:-: The Distributed File System (DFS) service manages logical volumes distributed across a local or wide area network. DFS is a single hierarchical file system, the contents of which are distributed across the network. DFS provides a logical tree structure for file system resources that may be anywhere on the network. Since the DFS tree is a single point of reference, regardless of the actual location of the underlying resources, you can access network resources based on a meaningful representation of the data. You no longer need to know and specify the actual physical location of files distributed across the network.
If the DFS service is stopped or disabled, users will be unable to access network data through the logical namespace and any attempt to configure a DFS root using the MMC DFS snap in will result in an RPC error. In order to for users to access the data, users will need to know the names of all the servers and shares in the namespace, and access each of these targets independently.
