The Remove-DnsServerResourceRecord cmdlet removes resource record objects from a Domain Name System (DNS) zone.
You can either use the Get-DnsServerResourceRecord cmdlet to specify an object, or you can specify the RRtype, Name and RecordData of the resource record you want to remove.
If you specify an RRtype or name and there are multiple resource records, you can specify the RecordData to delete a specific record.
If you do not specify RecordData, the cmdlet deletes all records that match RRtype and Name for the specified zone.
This command removes all root hints for a DNS server.
Example 2: Remove multiple A records
PS C:\> Remove-DnsServerResourceRecord -ZoneName "contoso.com" -RRType "A" -Name "Host01"
Confirm
Removing DNS resource record Host01 of type A from zone contoso.com on ROOT server. Do you want to continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): n
This command removes all A resource records in the contoso.com zone that have the name Host01.
This command removes all SRV records in the _msdcs.contoso.com zone that have the name _misc._tcp.
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.

-RecordData
Specifies the data contained in the resource record you want to delete.
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.
