Unbound or PowerShell?

[RayG]

If I look for a non existent name on the internet I see that the name does
no exist which is just fine

PS C:\> Resolve-DnsName -Name abc.abc.co.uk -Type A -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: abc.abc.co.uk : DNS name does not exist.
PS C:\> Resolve-DnsName -Name abc.abc.co.uk -Type AAAA -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: abc.abc.co.uk : DNS name does not exist.

PS C:\ Resolve-DnsName -Name abc.abc.com -Type A -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: abc.abc.com : DNS name does not exist.
PS C:\ Resolve-DnsName -Name abc.abc.com -Type AAAA -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: abc.abc.com : DNS name does not exist.

If I do the same thing on my local network I see the "Not enough memory..."
error

PS C:\ Resolve-DnsName -Name abc.abc.home -Type A -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: abc.abc.home : Not enough memory resources are available to
complete this operation.
PS C:\ Resolve-DnsName -Name abc.abc.home -Type AAAA -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: abc.abc.home : Not enough memory resources are available to
complete this operation.

The IPV4 name that resolves is configured as part of the local network when
unbound starts

PS C:\ Resolve-DnsName -Name test.home -Type A -DnssecOk -DnsOnly
-NoHostsFile

No IPV6 is configured on the local network

PS C:\ Resolve-DnsName -Name test.home -Type AAAA -DnssecOk -DnsOnly
-NoHostsFile
Resolve-DnsName: test.home : Not enough memory resources are available to
complete this operation.

If I remove the -DnsSecOK switch then I get the result I would expect.

PS C:\ Resolve-DnsName -Name abc.abc.home -Type A -DnsOnly -NoHostsFile
Resolve-DnsName: abc.abc.home : DNS name does not exist.
PS C:\ Resolve-DnsName -Name abc.abc.home -Type AAAA -DnsOnly -NoHostsFile
Resolve-DnsName: abc.abc.home : DNS name does not exist.

So is this a PowerShell issue or is it something that Unbound is
doing/returning to PowerShell?
