Add-DnsServerTrustAnchor

Add-DnsServerTrustAnchor is accessible with the help of DnsServer module. To configure DnsServer, go through this link.

Synopsis

Adds a trust anchor to a DNS server.

Description

The Add-DnsServerTrustAnchor cmdlet adds a trust anchor (DNSKEY record or DS record) to a Domain Name System (DNS) server. If no trust anchor is present, the cmdlet creates one. If you specify the DigestType parameter, the cmdlet adds a trust anchor delegation signer (DS) record.

If you specify the Root parameter the cmdlet retrieves the trust anchors from the URL specified in RootTrustAnchorsURL property of the DNS server.

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.

-Base64Data

Specifies key data.

-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. The acceptable values for this parameter are: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.

-Confirm

Prompts you for confirmation before running the cmdlet.

-CryptoAlgorithm

Specifies the cryptographic algorithm that the cmdlet uses for key generation. The acceptable values for this parameter are:

-Digest

Specifies the DS digest data.

-DigestType

Specifies the type of algorithm that the zone signing key uses to create the DS record. Valid values are one or more of the following:

-KeyProtocol

Specifies the key protocol. The default is Dnssec.

-KeyTag

Specifies the unique key tag that the DNS server uses to identify a key.

-Name

Specifies the name of a trust anchor on a DNS server.

-PassThru

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

-Root

Indicates that the cmdlet adds the trust anchor of the root zone from the URL specified by the RootTrustAnchorsURL property of the DNS server.

-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.

-WhatIf

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

—————EXAMPLE 1—————
Add a trust anchor to a DNS server
PS C:>Get-DnsServerResourceRecord -ZoneName “Tech.TOSSolution.com” -RRType “dnskey” –ComputerName DNS1 | %{ $_.RecordData | Add-DnsServerTrustAnchor -PassThru -Verbose -Name “Tech.TOSSolution.com”}
This command uses the Get-DnsServerResourceRecord cmdlet to obtain a DnsKey resource record from the DNS server DNS1 for the zone named sec.contoso.com. The command then uses the pipeline operator to send it to the Add-DnsServerTrustAnchor cmdlet to add a trust anchor to the current DNS server for this zone.

—————EXAMPLE 2—————
Add a trust anchor from the RootTrustAnchorsURL property
PS C:\>Add-DnsServerTrustAnchor -Root
This command adds the trust anchors from the URL specified by the RootTrustAnchorsURL property of the DNS server.
