Step-DnsServerSigningKeyRollover

Brian Lich|Last Updated: 3/28/2017

SYNOPSIS

Rolls over a KSK that is waiting for a parent DS update.

SYNTAX

Step-DnsServerSigningKeyRollover [-ZoneName] <String> [-KeyId] <Guid> [-Force] [-PassThru]
 [-ComputerName <String>] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Step-DnsServerSigningKeyRollover cmdlet rolls over a key signing key (KSK) that is waiting for an update from a parent delegation signer (DS). If a Domain Name System (DNS) server that hosts a securely delegated zone cannot check whether the DS record in a parent is updated, use this cmdlet to force a rollover.

Important: You must manually update the DS record in the parent before you run this cmdlet.

EXAMPLES

Example 1: Force a key signing key rollover

The first command uses the **Get-DnsServerSigningKey** cmdlet to gets keys for the signed zone Sec.Contoso.com.
PS C:\> Get-DnsServerSigningKey -ZoneName "Sec.Contoso.com"
KeyId                                  KeyType         CryptoAlgorithm    KeyLength  StoreKeysInAD   IsRolloverEnabled
-----                                  -------         ---------------    ---------  -------------   -----------------
5fe47b29-6bf8-457a-b457-e640893ebd53   KeySigningKey   RsaSha256          2048       True            True
aaf3301e-feb2-4ba7-8ac6-273c6bda75af   KeySigningKey   RsaSha1NSec3       2048       True            True
fbf3116f-b0ba-4bf8-bf35-68dab6d4765b   ZoneSigningKey  RsaSha1NSec3       1024       True            True
f760fcb5-577b-4237-b0b2-513e1f68ec72   ZoneSigningKey  RsaSha256          1024       True            True

The last command forces a KSK rollover that is waiting for a parent DS update on Contoso.com. The command performs a KSK rollover for the specified key in the zone named Sec.Contoso.com. 
PS C:\> Step-DnsServerSigningKeyRollover -KeyId 5fe47b29-6bf8-457a-b457-e640893ebd53 -ZoneName "Sec.Contoso.com" -Force

This example gets keys for a signed zone, and then forces a KSK rollover for one of the keys in the zone.

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.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ComputerName

Specifies a remote DNS server. Specify the IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name, for the DNS server.

Type: String
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-Force

Forces the command to run without asking for user confirmation.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-KeyId

Specifies the ID of the key for which to perform the KSK rollover.

Type: Guid
Parameter Sets: (All)
Aliases: 

Required: True
Position: 2
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-PassThru

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

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
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.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-WhatIf

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

Type: SwitchParameter
Parameter Sets: (All)
Aliases: wi

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-ZoneName

Specifies the name of the DNS zone in which the cmdlet performs the KSK rollover.

Type: String
Parameter Sets: (All)
Aliases: 

Required: True
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
