VMM 2016 and Network Controller certificate Issue’s

Since near the end of last year I was blessed with some hardware to test al lot of new features and stuff of Windows Server 2016, System Center 2016 and Azure Stack. Last week I experienced an issue with my Network Controller VM’s. In the end it turned out to be more of a VMM issue I think. But I wanted to share this with the world in case somebody else experienced this issue and does google for nothing because there is nothing to find about this issue.

Problem

I did the network controller and SLB Mux setup several weeks ago and all was running fine while all of a sudden I couldn’t change stuff in VMM anymore. Almost every action I did triggered this error:

Error (21426)
Execution of :: on the configuration provider  failed. Detailed exception: Unable to connect to the network service. Check connection string and network connectivity. Execution of Microsoft.SystemCenter.NetworkService::OpenDeviceConnectionEx on the configuration provider 3e2875a7-5831-4fb2-b388-1672e1c20fee failed. Detailed exception: System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
Check the documentation for the configuration provider or contact the publisher support.

Recommended Action

Troubleshooting

So I did a bunch of tests and troubleshooting

Hyper-V Virtual Switch Internal with NAT -Update-

This is a quick blog post to correct a “legacy blog” I made in January this year..

I haven’t been using any VM’s on my Surface for a long time, since then new Windows 10 builds have arrived. As Thomas Maurer discribes here things have changed.

If you were running the commands in my previous blog and have been using it you have come to the conclusion (I hope sooner as me 🙂 ) that the Nat VSwitch is gone and the VM’s depending on it have no network connection.

You can recreate it as internal VSwitch like this:


New-VMSwitch -Name VSwitch-NAT -SwitchType Internal
New-NetIPAddress –IPAddress 10.10.0.1 -PrefixLength -InterfaceAlias "vEthernet (VSwitch-NAT)"
New-NetNat –Name NATnetwork –InternalIPInterfaceAddressPrefix 10.10.0.0/24

But you will run in to an issue with the last command.

Go Hyper-converged with S2D

Windows Server 2016 is getting to it’s final RTM state within several months now. After that time we can start using Windows Server 2016 Storage Spaces Direct (S2D) for production environments and start using Hyper-converged stacks.

I’m not going to explain how Storage Spaces Direct works, this is just a blog about the setup. If you want some more info about S2D check out this link for an overview and for te more tech guys or girls look here.

I have spend some lab time setting up en using Storage Spaces Direct (S2D) and use Hyper-converged hosts and started this blog to share some info.

Beware that the info below is Lab stuf. I’ve taken some shortcuts to be able to setup S2D on VM’s with Virtual disks. So do not use this commands for you’re own setup, unless you are also running tests in VMs.

General Info

I have 2 VM’s running on a Windows Server 2016 TP5 physical box. The VM’s are enabled for nested virtualization to make sure a can start VM’s on the VM’s. Both VM’s have 10 disks attached to them. So no shared VHD, just 10 .vhdx files to both VM’s which makes a total of 20 .vhdx files. The VM’s are also running Windows Server 2016 TP5.

Create and attach disks

To create and attach the disks I used some powershell commands. I have 2 “Hosts” HV-01 and HV-02.
