  1. Fix -WhatIf, -Verbose, and -ErrorAction support in the DnsServer PowerShell module

    The new cmdlets for DNS policies in particular have inconsistent and downright broken support for -WhatIf and -Verbose.

    Example:

    Add-DnsServerClientSubnet -cn MyDC -Name 'Whatever' -IPv4Subnet 10.0.0.0/32

    That works if you explicitly add -WhatIf. But if I make the call inside an advanced function that SupportsShouldProcess and call the outer function with -WhatIf, the preference will NOT carry over. In order to do that, I have to use -WhatIf:$WhatIfPreference.

    The same is true with -Verbose, having to use -Verbose:$VerbosePreference because it won't inherit it.

    This is true on the cmdlets for:
    - Client Subnets
    - Zone Scopes
    - Query Reoslution Policies

    • DNS: Application high availability

      Hello,

      On your site "What's new in DNS Server in Windows Server 2016" is written that there will be a new feature called "DNS Policies", which can be used for "Application high availability". But i can't find this feature, which allows me to redirect clients to the healthiest endpoint like a failover-cluster. I'm not looking for a loadbalancer.

      Other People are looking too for this Feature and some documentation, when will it be available?

      This feature would be great for applications like ADFS and so on.

      • Broke RRAS

        At the moment PPPoE is broken in Windows Server 2016 over RRAS.
        It would be great if this could be solved.
        Till yet we're using Windows Server 2012. But we would like to upgrade but can't 'cause RRAS is broken.

        • DNS recursion using wrong NS for delegated zone CNAME

          When Server 2016 DNS Server has a delgation within a primary zone, CNAME records in that delegation result in queries to the delgation's name servers, not forwarders / root hints.
          For example:

          Primary zone: one.example
          Delegation: foo.one.example, with nameserver ns.bar.com

          In that delegated zone, there exists a record:

          baz.foo.one.example IN CNAME other.two.example

          two.example's zone, hosted by ns.somethingelse.com, has a record:
          other.two.example IN A 1.2.3.4

          From a client pointed at the DNS server, query baz.foo.one.example.

          I would expect the server to query ns.bar.com for baz, receive a reply of other.two.example, and then query either two.example's nameserver, or use the default forwarders…

            • Make Direct Access to work also User based

              "Direct Access" which unfortunately only works for domain joined clients (I dont get it why u made this fantastic technology computer based and not also user based which would also work for non domain joined computers)

              Giving customers access to our fileshares via https would be easy then.
              Currently almost all products from Microsoft are ready to deploy to external users via https the only thing left is classic filesharing.

              I know u want customers to use ur cloud services, but there are also a lot of companys which could not use them for compliance reasons, so please dont forget…

              • Fix Remote-NetIPAddress to work inside try/catch

                Writing a script to provision a machine - we first remove the IPAddress (and any default gateway), But sometimes there is no address. That;s fine - we just try/catch and move on, liike this:

                Try {
                Remove-NetIPAddress -InterfaceIndex $IfIndex `
                -AddressFamily IPv4 `
                -Confirm $false
                }
                Catch {Write-Verbose 'No IPAddresses found'}

                But instead of the nice write-verbose message, we get a fatal error:
                Remove-NetIPAddress : No matching MSFT_NetIPAddress objects found by CIM query for instances of the ROOT/StandardCimv2/MSFT_NetIPAddress class on the CIM server:

                • Provide useful parameters for Enable-NetLldpAgent

                  The Enable-NetLldpAgent , in order to be useful in proper management of a network, should allow setting TLV subtypes.

                  include the optional TLV 5 system name

                  MAC address is easily obtained by other networking tools. Using this as the information for mandatory TLVs is redundant and useless.

                    • Move the GlobalBlocklist to the ADS

                      Everytime you set up a new DC with DNS (integrated DNS Zones) you have to remember to clear the GlobalBlocklist in the Registry (when using wpad and isatap). If you set up new DC everytime a new OS is live, you have to remember for this every ~ 3 years. Please move the GlobalBlocklist to a Paramter in the integrated zones, so that every DNS Server with this zone get a real "Global" Blocklist. Or, at least, make the Blocklist visible in the mmc. Would make the search for the misconfiguration a lot faster.

                      • Expose whether DNS Client Server Address assigned by DHCP or Static

                        The Get-DNSClientServerAddress cmdlet does not provide information on whether or not the Server Addresses were assigned via DHCP or have been statically assigned.

                        This is presumably because the information is not provided to WMI/CIM.

                        This information is available by using NETSH, so it is available in the OS.

                        This would allow some problems in the xDNSServerAddress resource in the xNetworking DSC resource module (in the Resource Kit) to be solved.

                        For more information about the problem and why it is causing problems, please see this issue in the xNetworking resource module: https://github.com/PowerShell/xNetworking/issues/164

                        • Roll back network changes if not confirmed

                          If you change network settings, you should be prompted to confirm once the change has finished in the same way as display settings. If not the change is rolled back.

                            • Remove-DhcpServerv4Reservation [IP Address] removes all reservations in the scope, even if the IP is not a scope IP

                              When using Remove-DhcpServerv4Reservation and just giving it an IP address without using the option -IPAddress, the cmdlet removes *all* reservations and turns them into leases.

                              This should not happen if the IP address is not a scope IP identifier and should throw an error rather than removing all reservations.

                                • Provide logging around DNS record aging

                                  It would be nice to have DNS logging around what records would be scavenged if scavenging was turned on.

                                  Add a log (or easy PowerShell way) to pull the records that would be scavenged, following the built-in algorithm that DNS uses (https://technet.microsoft.com/en-us/library/cc959277.aspx)

                                  • DirectAccess documentation

                                    Comparing the documentation of DirectAccess for 2012 with other products, even DirectAccess 2008, I see that it lacks some in-depth insights that an Admin needs to be able to deploy and manage the component effectively.
                                    for example, I could not find a TechNet article describing in details, what happens from start to finish when a resource is being accessed through direct access:
                                    1. how is the NAT64 working? how does NAT64 translates address and which IPv4 address translates to which IPv6 and vice-versa? how does the component come up with those connection security rules in GPOs based on admin input…

                                    • Additional DHCP Server Failover Links

                                      In Server 2012, Windows Server had DHCP failover added to eliminate the requirement of clustering for HA. DHCP failover is limited to either a Load Balanced pair or an Active-HotStandby member.

                                      It would be nice to have a load balanced pair of DHCP servers, with a second failover association of a Hot-Standby at a remote location.

                                      • DHCP server should check network connection and start servicing IPs after Event 1041

                                        In the scenario where the DHCP server is started before the network switch, event 1041 is triggered and even after network is operational no IP addresses are services unless the DHCP service is manually started.

                                        • Send network configuration scripts on the hyperV hosts before running it

                                          When doing modifications on virtual network equipment in SCVMM, we often lose connectivity because a switch that allowed connection is deleted before another one is created. The problem is that scripts regarding network configuration are executed remotely, wich means that we’ll lose connectivity at some point and won't be able to complete the script. We believe it would be safer to send the script entirely to the hosts before executing it, so they could complete it without any remote help and reconnect when it has been executed.
