Hyper-V Server 2016 – HNV 1.0 – configuration lost after a while

Hi Expert,

Background and issue:

  1. Hypervisor: Hyper-V Server 2016 (note that it’s not Windows Server 2016)
  2. Deployment Model:Standalone
  3. Host Network: NIC teaming is used, and 2 physical NICs
  4. Hyper-V Network Virtualization: 1.0 (just consider it’s supported by Hyper-V Server 2016 since both HNV1 & HNV2 are supported by Windows Server 2016)
  5. Want to implement network isolation by using HNV 1.0
  6. run the following PowerShell command: 
New-NetVirtualizationLookupRecord -VirtualSubnetID "5001" -CustomerAddress "" -ProviderAddress "" -MACAddress "00155D971F27" -Rule "TranslationMethodEncap"

    7. after that, I can view the lookup record by running get-NetVirtualizationLookupRecord, but almost 3-5 minutes later, run get-NetVirtualizationLookupRecord again, no any output, seems that the configuration is totally lost.

Thanks in advance!

connecting to virtual machine management service hangs

Re-posting from this thread:

ORIGINAL POST from itr88:

Overview of environment

Hyper-V host 1 - Server 2016 - not domain bound - static IP - 4 nics (1 mgmt 2 guests and 1 spare)

- software additional to OS (webroot / labtech / veeam backup & replication)

- Runs two guests

-guest1 = DC / FS / DNS / DHCP / Backup server

-guest2 = WEBSERVER


This morning at 4am, the host reboot because of monthly patches (was not suppose to but a different story altogether), issue since then.

Can connect to host, but cannot connect to hyper-v manager, stuck on this: "connecting to hyper v management service"

We have done the following in troubleshooting

-Setup DHCP and DNS (as this is running on the DC that is not running atm)

-Run MOFCOMP %SYSTEMROOT%System32WindowsVirtualization.V2.mof

-Uninstall webroot and labtech and patches.

-Ran DCOM fixes and various other attempts to fix this

We have then booted from OS disc, reinstalled OS, after reinstall could access Hyper-V manager, imported VM’s, one failed, one succeeded, rebooted server and back to square one, unable to connect to hyper-v manager service.

Hyper-V still runs as we have the webserver running, and we can do some management via powershell, but that’s it.

Anyone encounter this or a similar issue, we’ve searched the internet and we can’t find anything closely related to this issue.


Did you end-up figuring out what happened, or find a fix?

We experienced the exact same issue on June 17th (the day after your post).

We have two VM host servers. After scheduled Windows patches in the middle-of-the-night, both rebooted.  One came up normal.  But when the other
host rebooted, it came up, but none of the VMs were online.

Same thing - It was stuck on "connecting to hyper v management service".

We tried the following, but had no luck

- Reviewed Error logs - (nothing useful, other than the service was not able to change the states of the VMs)

- Tried running MOFCOMP %SYSTEMROOT%System32WindowsVirtualization.V2.mof

- Uninstalled the recent Windows patches, rebooted

We’re running a Lenovo System X server.  We initially thought perhaps it was a firmware issue / incompatibility issue with the latest patch, but uninstalling
the patch didn’t help.

We ended up re-installing Window Server 2016, after updating all system firmware.  Ran all Windows Updates, then reinstalled Hyper-V role.

With no VMs added, we started Hyper-V manager and it came up.

We did not restore any of the prior VMs. Instead we created a new one. Started it. Rebooted the host, it all came up.

We added two more VMs, rebooted the host, all came up.

Since then, we added the rest of our VMs but have not rebooted the server.  We are definitely concerned about not having yet determined the root cause
of this issue, troubleshooting (besides reinstalling everything from scratch) or a fix.  Nothing we did brought the service back, so this is still of great concern.

Any new information you may have on this issue would be highly appreciated.

Hyper-V Manager – CredSSP Issue


I hope this is the right place to post this question. I have roughly 60 servers running Hyper-v Server Core 2012 r2. From time to time I have to use Hyper-V Manager to connect to one of the machines. Such as when the server loses power and shuts down. Sometimes
the RODC VM will come to the boot recovery options screen, after such a shutdown, and I have no choice but to use Hyper-V Manager to connect to it.

Recently our workstations were patched against the CredSSP vulernability, and as work around until we can get the servers patched, we’ve deployed a GPO disabling network level authentication. So, I can RDP into the Hyper-V core host using mstsc.exe, but I cannot
"connect" to the VM using Hyper-V Manager.

Has anyone seen this? The only way I can "connect" to the VMs on the the Hyper-V host using Hyper-V Manager is to uninstall the CredSSP patch on my Windows 10, 1803 PC.

I also don’t see a way to patch the Hyper-V Core server. I tried to install the patch slated for Server 2012 R2 core and it fails to install stating that the server doesn’t need this patch.

Anyway, I could use some help, if anyone has any to offer. If not, I will open a ticket with MS.

Proactively Identifying Potential Risk with VMware Skyline

Read full post . . . or

As part of our goal to continuously improve the customer support experience, Technical Support Engineers (TSEs) can now interactively view the proactive findings and recommendations delivered to customers today within the Skyline Operational Summary Report (OSR). Additionally, within the findings and recommendations, TSEs can view customer environment inventory information along with all Support Requests (SRs) for the particular customer they are assisting. All of this together enables Global Support Services (GSS) to better help our customers. These new capabilities are only available to those customers who have adopted VMware Skyline.

VMware Skyline is available globally to Premier Services customers along with a select number of Production Support customers. If you are interested in receiving proactive support from VMware, show your interest by signing-up for the Managed Access Program. We will continue to invite customers from the Managed Access Program as we scale proactive support services. Additionally, you can ask your VMware Account Team for information about how we’re radically transforming the customer support experience.

Going Beyond Break/Fix

When the circumstances exist that a SR is needed to troubleshoot an issue, TSEs will help the customer resolve the issue. Additionally, they can now review the customer’s proactive findings and recommendations as part of the SR process.

Perhaps the customer experienced an issue that was discovered by Skyline. In that instance, the TSE can immediately assist the customer with determining how many additional objects could be impacted by the same issue. TSEs can now help answer the question, how many more objects could be impacted by the same issue. Furthermore, the recommendation to resolve the issue has already been found, helping expedite the resolution of the issue across all impacted and potentially impacted objects.

Or, if a customer experiences an issue that requires a patch or update, the TSE can review the proactive findings and recommendations to determine if the patch or update required to resolve the original issue, could also resolve additional potential issues. This is not always the case, however, with more information available to TSEs, the better enabled they are to help customers.

Interactive findings and recommendations

Finding Potential Issues

TSEs can now view customer proactive findings and recommendations within a SaaS-based web application. This allows for better search and filter capabilities of findings and recommendations. TSEs can sort by issue severity, quickly looking at all critical findings within a customer’s environment. Or, a TSE can filter for only network-related findings if assisting a customer with a network-related SR. All of this together better enables our TSEs to better serve our customers and assist them beyond just problem resolution.

Technical Support Engineers can sort by issue severity or filter by compute, network or storage


Today, customers who have adopted proactive support with VMware Skyline receive an OSR. Within the OSR, customers are proactively notified of potential risks within their environment. Additionally, recommendations are provided for how to remediate those potential risks. Now, TSEs have this same information at their fingertips and can help customers with understanding potential risk within their VMware environment.

These new enhanced support capabilities are only available to customers who are receiving proactive support with VMware Skyline. This is just one of many steps VMware is taking is radically transform the customer support experience. Additional information about VMware Skyline is below.

importing and starting VMs in Hyper-V Server 2016 core using Powershell. All Virtual Machines are located on a diffierent partition


I’ve upgraded my infrastructure hastily and I done this before the correct way but as I sold my original server I had move the VM’s quickly but with consequences.

The correct way would have been to build the server, add to domain whilst it was live on a different Hyper-V host, assign static IP, change server name, installed windows feature e.g. Hyper-V,

I done this before and all worked fine as the DC is a VM which is was always online to authenticate against without issues e.g. AD, DNS, DHCP. however as mentioned I rushed it and now I’m stuck
in a workgroup environment on the Hyper-V server 2016 core install.

current Setup:

x1 HP ProLiant ML350 G6, 3 partitions with partition 1 is OS running Hyper-V server 2016 (Core OS), Partition 2 is VMS Datastore (I store all my Virtual machines here) and Partition 3 is ISO and
general software and files.

all other Hyper-V servers are offline and unavailable which would not help as DC VM is offline

Currently the Hyper-V server 2016 core is in a workgroup environment

IP address for the server are statically assigned, and I can ping them from w10 workstation

All workstations are on the domain there are no workgroups and I cannot connect to the domain as
the VM is offline

Firewall has been disabled on server and workstations to allow connectivity for ping, etc

routers been configured for DHCP, DG to allow connectively 


How do I import the DC VM into Hyper-V via PowerShell, so I can turn it on, then I can connect the server to the domain after configuring the server IP statically, so the IP & DNS point to
the DC VM and all will be good in the world again as I can use Hyper-V manager to connect and import the other VM via Hyper-V manager?


I have a Hyper-V server 2016 core install and I’m not sure how to import the virtual machine to get them started using PowerShell with VM’s located on a different partition, does anyone know how
to do this?

Thank you, God speed
