Description

The Start-DnsServerZoneTransfer cmdlet starts a zone transfer of a secondary zone from the master servers. You can do a full transfer, where the secondary Domain Name System (DNS) server gets a copy of all the resource records for the zone. You can also do an incremental transfer, where the secondary DNS server gets new and changed resource records.

A zone transfer forces a check of the version number in the master server Start of Authority (SOA) record. If the version number on the master server is higher than the secondary server version number, then a zone transfer begins that updates the secondary server. If the version number is the same, no zone transfer begins.

Examples

Example 1: Start a zone transfer

PS C:\> Start-DnsServerZoneTransfer -Name "contoso.com"

This command starts a zone transfer on the local DNS server for the secondary zone named contoso.com. The command does not use the FullTransfer parameter, so it performs an incremental transfer.

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
Position:	Named
Default value:	None
Required:	False
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[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ComputerName

Specifies a DNS server. If you do not specify this parameter, the command runs on the local system. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), Hostname, or NETBIOS name.

Type:	String
Aliases:	Cn
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-FullTransfer

Specifies that this cmdlet performs a full transfer. Without this parameter, the cmdlet does an incremental transfer.

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

-Name

Specifies the name of a zone. The cmdlet transfers records for this zone.

Type:	String
Aliases:	ZoneName
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
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
Position:	Named
Default value:	None
Required:	False
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
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

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