Set-DhcpServerv4DnsSetting

Configures how the Dynamic Host Configuration Protocol (DHCP) server service updates the DNS server with the client-related information.

Syntax

Parameter Set: Set1
Set-DhcpServerv4DnsSetting [[-ScopeId] <IPAddress> ] [[-IPAddress] <IPAddress> ] [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-DeleteDnsRROnLeaseExpiry <Boolean> ] [-DynamicUpdates <String> ] [-NameProtection <Boolean> ] [-PassThru] [-ThrottleLimit <Int32> ] [-UpdateDnsRRForOlderClients <Boolean> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Detailed Description

The Set-DhcpServerv4DnsSetting cmdlet configures how the Dynamic Host Configuration Protocol (DHCP) server service updates the DNS server with the client-related information. The ScopeId or IPAddress parameter must be specified with at least one of the optional parameters.

The ScopeId and IPAddress parameters cannot both be specified.

If neither the ScopeId nor IPAddress parameter is specified, then the specified DNS update settings are set to the server level.

This cmdlet modifies the effective DNS update setting and sets the setting on the specified reservation, scope or server.

Parameters

-AsJob

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-ComputerName<String>

Specifies the DNS name, or IPv4 or IPv6 address, of the target computer running the DHCP server service.

-DeleteDnsRROnLeaseExpiry<Boolean>

Specifies that the DHCP server service should delete the DNS resource records for the client after the lease expires.
The acceptable values for this parameter are: True or False. This parameter can only be set if the DynamicUpdate parameter is set to Always or OnClientRequest.

-DynamicUpdates<String>

Specifies the conditions under which to perform dynamic updates on the DNS server.
The acceptable values for this parameter are: Always, Never, or OnClientRequest.
- Always: The DHCP server service will always perform dynamic DNS registration of A and PTR records for the clients.
- Never: The DHCP server service will not perform any dynamic DNS registration
- OnClientRequest: The DHCP server service will perform dynamic DNS registration of A and PTR records if the client has requested the same in the DHCP client message.

-IPAddress<IPAddress>

Specifies the IPv4 address of the reservation for which the specified DNS update settings are being set.

-NameProtection<Boolean>

Specifies the enabled state for the DNS name protection on the DHCP server service.
If this parameter is set to True, then DNS name protection is enabled. If this parameter is set to True and there is an existing DNS record matching the name, then the DNS update for the client will fail instead of being overwritten.

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-ScopeId<IPAddress>

Specifies the scope identifier, in IPv4 address format, for which the DNS update settings are being set.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

-UpdateDnsRRForOlderClients<Boolean>

Specifies the enabled state for the DNS registration of A and PTR records for older clients which do not request DNS updates.

-Confirm

Prompts you for confirmation before running the cmdlet.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4DnsSetting

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Reservation

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Scope

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Outputs

The output type is the type of the objects that the cmdlet emits.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4DnsSetting

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Examples

EXAMPLE 1

This example sets the server level, or server-wide, DNS update configuration settings to always update DNS with leases entries and deletes the client entry from DNS when the lease expires.

PS C:\> Set-DhcpServerv4DnsSetting -ComputerName dhcpserver.contoso.com -DynamicUpdates Always -DeleteDnsRRonLeaseExpiry True

EXAMPLE 2

This example sets the DNS update configuration settings for scope 10.10.10.0 to update the DNS with leases entries based on client request, indicated in the FQDN option (option ID 81), and enables name protection by creating dynamic host configuration identifier (DHCID) resource records.

PS C:\> Set-DhcpServerv4DnsSetting -ComputerName dhcpserver.contoso.com -ScopeId 10.10.10.0 -DynamicUpdates OnClientRequest -NameProtection True

EXAMPLE 3

This example sets the DNS update configuration settings for the reserved IP address 10.10.10.5 to never update the DNS for client lease entries. This cmdlet clears all of the properties other than the property that is specified.

PS C:\> Set-DhcpServerv4DnsSetting -ComputerName dhcpserver.contoso.com -IPAddress 10.10.10.5 -DynamicUpdates Never
