Remove-DnsServerRootHint

Removes root hints from a DNS server.

Syntax

Parameter Set: InputObject
Remove-DnsServerRootHint [-InputObject] <CimInstance> [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-Force] [-PassThru] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Parameter Set: Parameters
Remove-DnsServerRootHint [-NameServer] <String> [[-IPAddress] <IPAddress[]> ] [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-Force] [-PassThru] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Remove-DnsServerRootHint cmdlet removes root hints from the list of root hints on a Domain Name System (DNS) server. When you remove a root hint from a DNS server, the DNS server cannot contact the root DNS server on startup and cannot answer queries for names outside its own authoritative zones.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Examples

Example 1: Remove all root hints on a DNS server

This command removes all root hints on the local DNS server. The Get-DnsServerRootHint cmdlet gets all root hints on the local DNS server and pipes the results to the Remove-DnsServerRootHint cmdlet.


PS C:\> Get-DnsServerRootHint | Remove-DnsServerRootHint

Example 2: Remove a root hint by using a resource record

In this example, the Get-DnsServerRootHint cmdlet gets a list of all root hints on the local DNS server. The command then pipes that collection to the Where-Object cmdlet.

Where-Object filters out the resource record to get the root hint for the DNS name server that is named H.Root-Servers.net. Where-Object then pipes the filtered DnsServerRootHint object to the Remove-DnsServerRootHint cmdlet, which removes the root hint.


PS C:\> Get-DnsServerRootHint | Where-Object {$_.NameServer.RecordData.NameServer -eq "H.Root-Servers.net."} | Remove-DnsServerRootHint
