Applies To: Windows Server 2012 R2, Windows Server 2012

Use the following procedures to display and review DNSSEC parameter values and settings using the DNS Manager console or Windows PowerShell. When you have completed the procedures in this topic, return to the parent checklist.

You can use DNS Manager or Windows PowerShell to review DNSSEC parameters and settings:

Review DNSSEC parameters and settings in DNS Manager

Membership in the Administrators group, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

To review DNSSEC parameters and settings in DNS Manager

  1. Open DNS Manager on a primary, authoritative DNS server, or connect to a primary, authoritative DNS server with DNS Manager.

  2. Right-click a DNSSEC-signed zone, point to DNSSEC, and then click Properties.

  3. Review settings on the following tabs: Key Master, Next Secure (NSEC), Trust Anchor, and Advanced.

  4. To review KSK settings, click the KSK tab, click a signing key under Key signing keys (KSKs), and then review information under Summary. You can also click Edit to review KSK settings.

  5. To review ZSK settings, click the ZSK tab, click a signing key under Zone signing keys (ZSKs), and then review information under Summary. You can also click Edit to review ZSK settings.

  6. Click Cancel when you have finished.

Review DNSSEC parameters and settings in Windows PowerShell

Membership in the Administrators group, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

In the Windows PowerShell examples that are used, replace secure.contoso.com with the name of the DNSSEC-signed zone that you wish to review.

To review DNSSEC parameters and settings in Windows PowerShell

  1. Open an elevated Windows PowerShell prompt on a primary, authoritative DNS server.

  2. To review a summary of zone settings, use the Get-DnsServerDnsSecZoneSetting cmdlet. See the following example.

    PS C:\> Get-DnsServerDnsSecZoneSetting -ZoneName secure.contoso.com
    
    ZoneName                      : secure.contoso.com
    IsKeyMasterServer             : True
    KeyMasterServer               : DC2.contoso.com
    KeyMasterStatus               : Online
    DenialOfExistence             : NSec3
    NSec3HashAlgorithm            : RsaSha1
    NSec3Iterations               : 50
    NSec3OptOut                   : False
    IsNSec3SaltConfigured         : True
    NSec3RandomSaltLength         : 8
    NSec3UserSalt                 : -
    DnsKeyRecordSetTTL            : 01:00:00
    DSRecordSetTTL                : 01:00:00
    DSRecordGenerationAlgorithm   : {Sha1, Sha256}
    DistributeTrustAnchor         : {None}
    EnableRfc5011KeyRollover      : True
    ParentHasSecureDelegation     : False
    SecureDelegationPollingPeriod : 12:00:00
    PropagationTime               : 2.00:00:00
    SignatureInceptionOffset      : 01:00:00
    
  3. To review a summary of signing keys, use the Get-DnsServerSigningKey cmdlet. See the following example.

    PS C:\> Get-DnsServerSigningKey -ZoneName secure.contoso.com
    
    KeyId                                  KeyType         CryptoAlgorithm    KeyLength  StoreKeysInAD   IsRolloverEnabled
    -----                                  -------         ---------------    ---------  -------------   -----------------
    1adabf48-5039-4e71-907c-99ff87f43564   KeySigningKey   RsaSha256          2048       True            True
    08bf6bd0-b242-49d5-8674-eff9d338ea2f   ZoneSigningKey  RsaSha256          1024       True            True
    
  4. You can also review detailed information for signing keys using Format-List (fl). See the following example.

    PS C:\> Get-DnsServerSigningKey -ZoneName secure.contoso.com | fl *
    
    KeyId                         : 1adabf48-5039-4e71-907c-99ff87f43564
