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.

Examples

Example 1: Add a trust anchor to a DNS server

PS C:\> Get-DnsServerResourceRecord -ZoneName "sec.contoso.com" -RRType "dnskey" -ComputerName DNS1 | %{ $_.RecordData | Add-DnsServerTrustAnchor -PassThru -Verbose -Name "sec.contoso.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.

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.
