Internal switch reset to public network profile after each reboot

Hi, I’ve created an internal switch with NAT (Windows 10 Pro for Workstation, OS Build 17763.529) and added to the switch some VMs. I set the profile to private using Power Shell, in order to allow the host and the guests to see each other. The internal
switch is bundled with the Default Switch as Unidentified network, and executing the Power Shell command on it changes the Default Switch’s network profile to private too.

But after reboot the profiles of Default Switch and the internal switch are reset to Public. Changing the Networks List Manager Policies of
Unidentified network to private with secpol.msc leads to problems in the creation of the Default Switch on startup.

Is there a way to preserve the Internal Switch private status after reboot, without having to execute the Set-NetConnectionProfile every time?

Thanks for your help, Marco

When restarting Hyper-V server on Windows 2016 it shuts down, after security update

Hi

After running Windows Update we are unable to restart the Hyper-V Windows 2016 server: when restarting the Hyper V Server it shuts down instead, and we need to physically push the power button on the server in order to start it again.

The Virtual Windows 2016 server does not have this problem, and restarts fine.

In the event Viewer we have the following information:

The process C:WindowsSystem32RuntimeBroker.exe (HYPERV) has initiated the restart of computer HYPERV on behalf of user HYPERVAdministrator for the following reason: Hardware: Maintenance (Planned)
 Reason Code: 0x84010001
 Shutdown Type: restart
 Comment:

Event ID: 1074

*****

The kernel power manager has initiated a shutdown transition.

Shutdown Reason: Button or Lid

Event ID: 109

*****

The WinRM service is not listening for WS-Management requests.

 User Action

A hint would be nice

Hyper-v

Hello, 

I have a server 2012 machine set up with Hyper-V installed.

I would like to have some users have access to use (not modify hardware etc) some vm’s (not all of the vm’s) 
The Users may access their vm’s simultaneously.
Users would ideally be able to stop/start/restart their vm’s.
The users can either be local or obtained from an already-existing Active Directory.
How can i assign the user rights for the vm’s, and what do i need present on the user’s PC’s?
Thanks

How to create Virtual Switch with NIC teaming with multiple VLAN

Hi,

 Please help me to resolve my problem.

I have 

1 Server 2016 (Physical Machine)

NIC teaming with LACP Dynamic (NIC3 + NIC 4) — Both NIC are connected on different Switch(Arista switches) port (SW1-E24 and Sw2 -E24)

Switch 1, 2 Configuration

Interface Port-Channel15

Switchport trunk allowed vlan 40,70

Switchport mode trunk

Mlag 15

|

|

Interface Ethernet 24

Switchport trunk allowed vlan 40,70

Switchport mode trunk

Channel-group 15 mode active

|

|

Question 1:  when i create NIC team with LACP, i need to define the VLAN ID 40 on  NIC team otherwise the server is inaccessible from NIC team. how to resolve this ?

I also add the interface on NIC team with VLAN 70.

Question 2: When create virtual switch(Switch-VLAN40) from Hyper-V virtual switch manager, with Connection type External Network, Allow Management Operating system to share this network adapter and specific the NIC team VLAN 40 network.

The server become inaccessible. same happen with VLAN 70. how can i resolve it.

Server replication, remote site

Hello

I am facing a problem, my hyper V server has only one physical network card, and my provider is not able to interconnect my two servers via their solution (Vrack) which requires a physical network card dedicated to this
interconnection
.

My configuration:

HV1:
1 VM of production + 1 VM Domain controller

HV2:
1VM which will be the replicate of the production VM + 1
testing VM

My need :

Replicate production Virtual Machine + Join
production and testvirtual machinesto the domain.

The replication method (HyperV or Veeam) does not matter to me, as long as it works.

Problem:

I only have ONE physical card on my HV’s

I do not have access to routers that bridge between my hypervisors and the internet

Do you have any ideas

Is it technically feasible with a single network card?

Thanks !!

VPN connection to host, RDP to VMs

Hi

I’m trying to sort out a situation. We have two hosted servers, Server 2012R2 with the RRAS and Hyper-V roles, each with a single NIC and they are connected directly to the internet (So public IPs). On each host is multiple VMs connected. Each VM has its own
public IP and used by our roaming clients. We are trying to cut down on our public IP needs so we want to change how the system works.

We want our roamers to start a VPN connection to the host machine, then use RDP through the VPN to connect to their respective VM… But I cannot seem to get the RRAS to play fair. The clients don’t need to access the host machine at all, just the VMs. I have
managed to get the VPN side of things to connect and that is about it. I cannot seem to figure out how to allow routing to the internal VMs. VMs also still need internet access.

I’m stuck and need some help. I want to start fresh and take it from there.

RemoteFX3 Screen Tearing NVIDIA Quadro P4000

Hello,

my IT dpeartment is trying to get RemoteFX working under Windows Server 2012 R2 but we ran into some trouble. We are using a HP Proliant 380p GEN8 with NVIDIA P4000 GPUs. The server recognizes the GPUs and we can configure RemoteFX on the host and the guest
VMs. The VMs also see the RemoteFX WDDM device in the device manager. The main problem we are having right now is the performance of the VMs, the cpu offloading during graphic intense workloads works just fine but the overall performance isnt bearable. If
we manage to connect to the VM with the configured 4 monitors (which is maybe a 3 in 10 chance of happening), the resulting screen tearing makes it so working isnt possible. We’ve tried configuring the NVIDIA control panel and the BIOS of the HP server but
without any results. 

If someone has any experience with RemoteFX under Windows Server 2012 R2 and can help me with this problem i’d be gratefull

Thank you
