xDnsServerAddress (IPv6) fails with Property NameServer does not exist

[roneystein]

In an IPv6 interface, after disabling DHCP and configuring the interface address, attempting to configure DNS server address results in:

"Property NameServer does not exist at path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\Interfaces{#interface#}."

Where #interface# is the interface identifier.

Configuration IPv6Dnsserver
{
    Import-DscResource -Module xNetworking
    Node 'localhost'
    {
        xDnsServerAddress IPv6DnsServer
        {
            Address        = '#ipaddress#'
            InterfaceAlias = 'Ethernet'
            AddressFamily  = 'IPv6'
            Validate       = $false
        }
    }
}

With #ipaddress# being the DNS Server IPv6.
Worked fine on version 4.0.
OS is Windows 10.

Hi @roneystein - I've identified the cause of the problem I think and should be able to fix it. I'll submit a PR today or tomorrow to get this fixed and it should go in before the next release.

Thanks for submitting this.

FYI: It is caused if the NameServer property does not exist for an interface in the registry. This error should have been suppressed but the Get-ItemPropertyValue cmdlet ignores the -ErrorAction SilentlyContinue parameter.

@roneystein - I've submitted a PR for this and should get it merged over the next few days (depending on how busy the other maintainers are). Thanks again!
