The xDhcpServer DSC resources are used for configuring and managing a DHCP server. They include xDhcpServerScope, xDhcpServerReservation, xDhcpServerOptions and xDhcpServerAuthorization.

Please check out common DSC Resources contributing guidelines.

• xDhcpServerScope sets a scope for consecutive range of possible IP addresses that the DHCP server can lease to clients on a subnet.
• xDhcpServerReservation sets lease assignments used to ensure that a specified client on a subnet can always use the same IP address.
• xDhcpServerOptions currently supports setting DNS domain and DNS Server IP Address options at a DHCP server scope level.
• xDhcpServerAuthorization authorizes a DHCP in Active Directory.
• This resource must run on an Active Directory domain controller.

• IPStartRange: Starting address to set for this scope
• IPEndRange: Ending address to set for this scope
• Name: Name of this DHCP Scope
• SubnetMask: Subnet mask for the scope specified in IP address format
• LeaseDuration: Time interval for which an IP address should be leased
• State: Whether scope should be active or inactive.
• Ensure: Whether DHCP scope should be present or removed
• ScopeID: Scope Identifier. This is a read-only property for this resource.

• ScopeID: ScopeId for which reservations are set
• IPAddress: IP address of the reservation for which the properties are modified
• ClientMACAddress: Client MAC Address to set on the reservation
• Name: Reservation name
• AddressFamily: Address family type. Note: at this time, only IPv4 is supported.
• Ensure: Whether option should be set or removed

• ScopeID: ScopeID for which options are set
• DnsServerIPAddress: IP address of DNS Servers
• DnsDomain: Domain name of DNS Server
• AddressFamily: Address family type
• Ensure: Whether option should be set or removed

• Ensure: Whether the DHCP server should be authorized.
• DnsName: FQDN of the server to authorize. If not specified, it defaults to the local hostname of the enacting node.
• IPAddress: IP v4 address of the server to authorized. If not specified, it default to the first IPv4 address of the enacting node.

• Added xDhcpServerAuthorization resource.
• Bug Fix LeaseDuration is no longer mandatory for xDhcpServerScope resource.
• Bug Fix DnsServerIPAddress is no longer mandatory for xDhcpServerOption resource.
• Bug Fix corrects verbose display output in xDhcpServerOption resource.

• Fix "Cannot set default gateway on xDhcpServerOption".

• Bug fix, enables creating more than 1 DHCP server scope.

• Initial release with the following resources
  • xDhcpServerScope
  • xDhcpServerReservation
  • xDhcpServerOptions
