Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

I have a 2012 Server R2 Standard Hyper-V VM (Server1) that has Remote desktop services with all the roles on it. This is for Published Apps. I setup a second Hyper v VM (Server2) to replace Server1. I access Server1 by going to http://rds.domain.com/rdweb and the cert is for rds.domain.com. I can access this fine and open the apps.  I access Server2 by going to http://access.domain.com:8443/rdweb and the cert is for access.domain.com this is a self signed cert for now. When i go to http://access.domain.com:8443/rdweb and login and run an app i get this error " Your Computer cant connect to the remote computer because the remote desktop Gateway server address requested and the certificate subject name do not match." If i select view certificate i see the Server1 cert rds.domain.com.

I think this has to do with port 3389 and that when i launch the app its pointing to the server1. Is there a way to change the port on Server2 if this is the issue?

Hello Experts
i need some advise on best way forward to setup a 3 node hyper v failover cluster using windows server 2016.
I got 3 Dell Servers all identical config,  and 1 dell SAN storage. 2 Dell iSCSI 10GB swithces,  2 Cisco c3750 switches, 1 dell server to act as standalone DC.

i have been doing 2 node clusters in past but never done a 3 node cluster. so need some advise on network config as in 2 node cluster i used to connect two servers via direct crossover cable for cluster heart beat etc and use cluster quorom disk .

so any tips will be much helpful.

Physical server died, it had 3 VM's running on it.   Physical server was a windows 2012 r2 standard
We were able to extract the manual copies of the vhds, snapshots, and the config files. some of the vm's had multiple snapshots.

we have a spare server that we loaded, also with windows 2012 r2 standard and installed hyper V on it.
What's the process of importing the VM's onto it (keeping in mind that they have snapshots, etc).
14 Hyper v hosts, managed via SCVMM running on a c7000 blade chassis with 10G interconnects - All intel CPU's, 192 GB RAM etc. Broadcom nics but vmq disabled.

Dell 10GB switch managing ISCSI to the chassis and SAN.

IBM v3700 with 2 expansion trays.
5x400GB SSD's in raid 10 for easy tier, 4 x raid raid 6 arrays of 10k disks. (lets call it 8 disks each array) 1 x large Raid 6 of Nearline drives.

The environment is well loaded and runs fine running a varying number of VM loads.

We monitor extensively all performance etc and know that there are no issues with CPU, memory or disk access etc UNTIL:

If a backup is misbehaving, someone is doing a high disk load activity or something like deploying a templated VM, all users across all VM's notice a slowdown or lockup.

DISK IO on the SAN is neligable, Ram usage, CPU Usage does not spike and there only a small increase in the amount of network traffic.

It seems like everything runs well, but just a small event can cause issues.

Looking for ideas, configuration changes or otherwise.
I am wanting to set a user up with a roaming profile. they have a surface they use at the office. When they are out they vpn in to connect to resources. I am setting them up a hyper v machine that I want to look and feel like there current desktop. Any ideas on this one.
We have a two server boxes in a HA Cluster setup

When a node is shutdown, the VMs on that node are not appearing /migrating to the other node thats in the HA cluster.

When both nodes are on, VMs can happily migrate from node to node without a problem.

Why is this ?
I've got a Win 10 Pro laptop with 16 GB of ram. I've got Hyper V installed & another Win 10 VM running on it, for working with point of sale software.
In settings, I've specified 8 GB of ram, dynamic is enabled, 512MB min & 1048576 max (not sure where I came up with that).
System properties shows 7.91 GB installed & 1.88 available, which is about what task manager shows.
How can I increase this? Uncheck dynamic?
I'm in the middle of a project & didn't want to start tinkering with things, being wary of the Murphy's law thing...
I have a Hyper-V Manager in a workgroup on and a Freecom NAS drive on Both are in a workgroup called JGL.
When creating a new VM I point the .iso location to \\\Software\server2016.iso which it accepts but when I click finish I get the error:
From Windows Explorer I can map to \\\Software and I'm prompted for a username and password and I click "remember" (subsequent connects don't require credentials)
I can't see anywhere in Hyper-V where I can enter credentials.
Server 2016 Standard with two running Hyper-V VM's. One running as the PDC and the other as the Exchange server. Months ago we had to turn off the original Exchange server because it was having problems and Dell didn't ship the operating system. To get exchange up and running  we installed a third VM using a trial version of Server 2016 Standard. This configuration has been running for months without any errors. To clarify VM's; 1. PDC, 2 Exchange (original), 3. Exchange2 (2016 trial version).

The VM running the trial version of Server 2016 (Exchange2) we want to power down and migrate the exchange server, or EDB to the original Exchange VM.

What is the best way to move the exchange server from one VM to the other? Ideally with the least or no downtime to end users? Is this possible?

As of now I've copied the EDB from Exchange2 and am thinking of using a tool to migrate this from EDB directly into the new server.
I have a Windows 2016 Hyper-V manager with two guest VMs. One guest VM is a Domain Controller and the other is a SQL DB server which is a member of the domain.
The Hyper-v server is in a Workgroup. Should I make the Hyper-V server a Domain Controller for a separate domain and then make resources such as a NAS, members of that domain?
I'd like to access the NAS from the Hyper-V manager for VM builds and Disaster Recovery and I'd also like to access the NAS from the Guest VMs for software images.

I keep getting the following error when creating a cluster on Hyper V

An error occured while creating the cluster and the nodes will be cleaned up.
Please wait...

There was an error cleaning up the cluster nodes. Use Clear-ClusterNode to manually clean up the nodes.

An error occurred creating cluster XXX-XXX-XX Cluster.

Patch levels and networking are all sound.
Hi guys,

We implement Skype for Business Cloud Connector on-premise  VMs on Hyper-V. (Building 1)
Also take a SIP Trunk from our ITSP in Building 2. There is some questions as below:
1-      Is it possible to forwarding SIP port from IP static in building 1 to IP static in Building2?
2-      How should I edit configuration.ini file? Specific in voice gateway section… put IP static that related to building 2 or what?
3-      Where should I use my SBC IP & IP address which I take with SIP Trunk modem
PS: Network structure and Configuration file is attached. Please help us in this regards ….
Thank you
Using Server 2016 Hyper-V, I'm comparing Dynamic vs. Fixed Disks using 10,000 RPM SAS drives and a Dell PERC H730.  
I have currently set all four partitions on the two VM's to dynamic disks but wondering if it is worth the effort to convert them all to fixed disks.
The partitions are all using VHDX files (two partitions for each VM--operating system and data for each).   According to this web page, dynamic disks are actually faster in "overwriting" than fixed disks so perhaps I should keep the disks to dynamic:
Thank you.
Can two Hyper V Hosts be configured to see the same shared SAN storage like vCentre does for clustered Esxi hosts ?
I have a management console on a Windows 7 VM. I need to create on for a new site. The software is exactly the same, just needs a IP change and a few configuration changes to create on for a new site. Can I copy the VM I have an reconfigure it for the new site. It will set on the same Host. I know how to import and export the VMs but not sure what I need to do for the domain to see it as a new PC. Please advise. We use Windows Server 2012 R2 standard and Hyper-V.

New creating VMs so any recommend links would be appreciated as well.


I have Hyper-V cluster and running two Hyper-visor on  with attached Dell Storage and Dell  Server.  I am using  Power Vault Modular disk storage Manager to manage the Array.

while we double click on Storage Array I am getting the following error

 java.lang.NullPointerException" has occurred.  

Can any once please more with Dell storage experience  help me how to overcome this problem.


I was reading the above mentioned article, and it appears to suggest not using dynamic disks if at all possible.  It suggests not using dynamically expanding disks because of reduced performance by increased overhead and fragmentation.

I usually assign the guest VM OS as a fixed disk.  This also applies to virtual disks with databases.  However, for growing company file storage, I usually assign the virtual disk as dynamically expanding with a cap imposed.

I will be installing a new Windows 2016 hyper-v server with two vms.  On one of the two vms I was going to assign the guest os (80Gbs) and a database virtual disk (150Gbs) as fixed virtual disks.  Their company data is currently at 330Gbs, and growing, and I was going assign it as a dynamically expanding disk with a cap of 800Gbs.   As a rough estimate the amount of disk space will probably double within 4 or 5 years.

After reading this article, I may want to consider assigning this virtual disk as fixed (800Gbs), and be done with it.  I understand, a large fixed disk has drawbacks when it comes to moving/restoring the entire drive should that be necessary.  However, fragmentation is just as an important issue over the near/distant future.  Also, I purchased this server with a more than adequate amount of overall disk space to last many years, so disk space is not …
When trying to connect to a VM through Hyper V manager getting an error "An authentication error has occured (Code: 0x8009030e). Remote Computer : Server1.domain.local" and another error right after "Cannot connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator. Would you like to try connecting again?"
I can remote into the VM through RDP and i can connect to the host through another Hyper V manager and connect to the VM. Seems to be a UA issue on the host of that Vm. Any ideas?

I have 2 windows 2016 hyper-v hosts in a workgroup and I plan to join those 2 hosts to domain.
Hosts have 2 DCs(2008r2) as a guests VMs and couple other member servers.
Reading this article I dont expect problems running DCs on domain joined hosts
Should I expect any problem if I join hyper-v hosts to domain?
I plan to shutdown guests VMs and join host(s) to domain and than power on guest VMs.

I am  new in SCVMM  ( hyper-v ) and comes from VMware background. i have  recently been tasked  to create to development server from critical running VM's  in cluster environment.  i have looked into this but cannot find snapshot operation the reason we are using System Centre 2012 Virtual machine manager where it only gives option for checkpoint.
 My question is  checkpoint is similar to snapshot and how  I can safely  create two development server using   Two live production VM's ,.
Please can any one expert on hyper-v en light  best way to achive this.

Using Windows 2016 Hyper-V I have created a couple of VMs and a Test VM so that I can prove my backup and restore process.
I have successfully backed up my Test VM and so have now deleted it using the Hyper-V Manager. Using Windows Explorer I have also deleted its associated Test.vhdx file. However, there are some .VMRS files that I can't delete because they are in use
Delete errorHow can I remove these files

2 windows 2016 with hyper-v role in a workgroup(2 hosts in a workgroup)

I have 2 guest DCs(2008r2) on one host and I need to migrate one DC on another host.

Since hosts are in a workgroup live migration is not an option?

Is this proper way to migrate DC on another workgroup host?


Its DC server,so Im careful because I dont want to change SID or something like that J

So,I just need to copy(or cut and paste?) vhd disk(without configuration files?) to another host and attached to new VM?

Is there anything in this process to pay attention?
I have converted 3 Physical servers (server 2012 R2) to VMs using P2V program. I have now got all 3 VMs up and running in hyper-v (server 2016). I have created a virtual switch and  attached the VMs to it. It is configured as an external virtual switch so that the VMs can communicate with the rest of the network.

The problem is I cant ping anything. I cant even ping the hyerp-v hosts ip address?

I have created a fresh virtual switch and still nothing,

All the VMs are configured with static ip addresses.

Any ideas?
I created 2 Vm with the hyper-V (windows 2012).  At the first cm i install and configure the AD services,DHCP and DNS roles. The problem is that when
i tried to join the domain i received the error :
The error was: "This operation returned because the timeout period expired."
(error code 0x000005B4 ERROR_TIMEOUT)

I attached the complete file with the error error.txt

What is going wrong?
