问题
I created a new NAPTR records using the GUI. However I'd like to delete one of them using PowerShell.
I can prove there are 2 records:
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
HostName RecordType Type Timestamp TimeToLive RecordData
-------- ---------- ---- --------- ---------- ----------
foo NAPTR 35 0 01:00:00
foo NAPTR 35 0 01:00:00
> $OldObj = Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
> $OldObj[0].RecordData.Data
010001000155036F6E65036F6E6500
> $OldObj[1].RecordData.Data
0200020001550374776F0374776F00
> $OldObj[2].RecordData.Data
>
If I try to delete the records, I can do it interactively:
> Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR
Confirm
Removing DNS resource record set by name foo of type NAPTR from zone example.com on TOMDEV server. Do you want to continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
Sadly that deletes both of the records!
What if I try to remove the object, instead?
> $OldObj[1] | Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo"
Confirm
Removing DNS resource record set by name foo of type NAPTR from zone example.com on TOMDEV server. Do you want to
continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
Get-DnsServerResourceRecord: Failed to get foo record in example.com zone on TOMDEV server.
Oh no! That deleted both records!
Can I specify a single record to Remove-DnsServerResourceRecord?
Here's what I've tried:
This just gets rejected out-right:
> Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR -RecordData "0200020001550374776F0374776F00"
Remove-DnsServerResourceRecord: InputObject for resource record has an invalid value. Failed to remove the resource record on TOMDEV server. Please check extended error for additional details.
If I try to capture the one record and pipe it to Remove-, that removes both records:
# First, we single out exactly one record:
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR | Where-Object {$_.HostName -eq "foo" -and $_.RecordData.Data -eq "0200020001550374776F0374776F00" }
HostName RecordType Type Timestamp TimeToLive RecordData
-------- ---------- ---- --------- ---------- ----------
foo NAPTR 35 0 01:00:00
>
# That worked! Let's use that query and pipe it to Remove!
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR | Where-Object {$_.HostName -eq "foo" -and $_.RecordData.Data -eq "0200020001550374776F0374776F00" } | Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -Force
# Nope, that removed both records!
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
Get-DnsServerResourceRecord: Failed to get foo record in example.com zone on TOMDEV server.

It isn't removing everything at "foo", just the NAPTR records there. (In fact, the message says "record sets" (plural), not "record".
Let's prove that by creating an A record plus 2 NAPTR records all at label "foo". We'll see the same problem:
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo"
HostName RecordType Type Timestamp TimeToLive RecordData
-------- ---------- ---- --------- ---------- ----------
foo A 1 0 01:00:00 4.4.4.4
foo NAPTR 35 0 01:00:00
foo NAPTR 35 0 01:00:00
> $OldObj = Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
> $OldObj[0].RecordData.Data
010001000155036F6E65036F6E6500
> $OldObj[1].RecordData.Data
0200020001550374776F0374776F00
> $OldObj[2].RecordData.Data
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR | Where-Object {$_.HostName -eq "foo" -and $_.RecordData.Data -eq "0200020001550374776F0374776F00" } | Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo"
Confirm
Removing DNS resource record set by name foo of type NAPTR from zone example.com on TOMDEV server. Do you want to
continue?

How can I delete a single NAPTR record?
回答1:
If you are saying you want to delete one of them, and it does not matter which one, are saying you also tried this:
Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR |
Where-Object {
$PSItem.HostName -eq "foo" -and
$PSItem.RecordData.Data -eq "0200020001550374776F0374776F00"
} |
Select-Object -First 1 |
