[<CommonParameters>] Description
The Set-DnsServerRootHint cmdlet replaces the list of root hints on a Domain Name System (DNS) server. This cmdlet overwrites the list of root hints with the list of root hints that you specify by using the InputObject parameter.
Examples
Example 1: Change the IP address of a root hint
The first command adds a root hint for the DNS name server that is named H.Root-Servers.net and the IP address 172.24.60.128.
PS C:\> Add-DnsServerRootHint -NameServer "H.Root-Servers.contoso.net" -IPAddress 172.24.60.128
The second command assigns the value that is returned by the **Get-DnsServerRootHint** cmdlet to the variable $a. **Get-DnsServerRootHint** gets a list of all root hints on the local DNS server. The command then passes that collection to the **Where-Object** cmdlet by using the pipeline operator. **Where-Object** filters the resource record to get the root hint for the DNS name server that is named H.Root-Servers.net.
PS C:\> $a = (Get-DnsServerRootHint | Where-Object {$_.NameServer.RecordData.NameServer -eq "H.Root-Servers.contoso.net."} )
The third command sets the value of the IP address of the root hint to 172.24.60.132 for the DNS name server H.Root-Servers.net.
PS C:\> $a.IPAddress[0].RecordData.Ipv4address = "172.24.60.132"
The fourth command replaces the list of root hints on the local DNS server with the root hint for the DNS name server H.Root-Servers.net.
PS C:\> Set-DnsServerRootHint $aThis example adds a root hint to the list of root hints on a DNS server and changes the IP address of the root hint.
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.

-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
Specifies a remote DNS server. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

-InputObject
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
| Type: | CimInstance |
| Position: | 1 |
| Default value: | None |
| Required: | True |

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

| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ThrottleLimit
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.
