Can Hyper-V host join a domain of a virtual machine domain controller on that same host?

Learning about Failover Clustering with Hyper-V. I have two hyper-v nodes(servers). I want to add them to a failover cluster, but it said that the nodes must be in a domain to join failover cluster.
Can I create a domain controller role on a virtual machine hosted on that same node and join that node to the domain?
Can I just create a role on one of the two nodes along with hyper-v role and join the second node to the domain?

You can create
an AD VM and join the Hyper-V host to it in Server 2012 (or Hyper-V Server 2012, the preferred OS for running a Hyper-V Cluster). This did
not work in any previous version of Windows.
This would be a really horrible idea for a production environment, but suitable for a lab/training.
Also, you only need one host/node to form a cluster (though it probably throws errors/warnings if you do)

How to join a Domain Controller Server to an two-tier (SQL Server 2012) and Sharepoint 2013 (SP2013) farm

Hi,
I am trying to build a 3-tier SharePoint 2013 farm.
1. SQL Server 2012, Windows 2012 VM
2. DC Server, Windows 2012 VM
3. SharePoint 2013, Windows 2012 VM
I didn't built the DC server. Someone else did. However, I created about 14 service domain user accounts for SQL Server and SharePoint install and operation.
I was able to join the SQL Server into the SharePoint server farm using SharePoint 2013 Product Configuration Wizard. When I start the Central Admin, and click on Servers in the Farm, I only see the SharePoint server and SQL server,
but the DC server is not listed. Any suggestion on what did I miss?
Thanks
Jean

You cannot join the Domain Controller to your SharePoint farm. You must instead join each server from that farm to the domain that is served up by that DC. You will want to uninstall SharePoint and probably SQL before you do this. If it's
an option, I would re-provision your VMs completely and start fresh. Once you login to a new server, join that server to the target domain like this:
http://www.petri.co.il/join-windows-server-2012-to-domain.htm
You'd have to ensure that your DNS resolves to the target domain on the server being joined to the domain. If it doesn't, you can always use HOSTS entries to overcome that in the short term.
Once you've joined both the future SQL and SharePoint servers to the domain, you can install SQL Server and then SharePoint on their prospective servers to create your farm.
I trust that answers your question...
Thanks

How can I know the version of Application Server Java Virtual Machine

How can I know the version of Application Server Java Virtual Machine?
Thanks a lot.

Thats easy. Your jdk/jre are located in the App Server home directory. Just run the java command under the jdk directory with the "-version" switch and it will provide you with detailed information about your VM.
For example if you're doing it at command prompt it will be something like
java -versionI hope this will be useful to you.

Can I assign several physical storage locations for each virtual machine when using the replication-feature from Hyper-V 2012 R2?

Hi everyone,
I have 2x physical servers running Hyper-V 2012 R2. Each hosts several virtual machines. The VHDs of the VMs are stored on several dedicated physical disks to have a performance boost. For exampe if VM A has two VHDs attached I made sure that the VHDs are
on different physical disks to have them not slow-down each other in case of intensive disk accesses.
So far so good. I was looking forward to the replication-feature. The idea is to have the two physical servers have their primary running VMs being replicated to the other physical server and vice-versa. I was hoping to have the chance to choose for each
individual VM where the replicated VHD will be stored. But instead I can only see the one location/path which is configured in Hyper-V Manager when I activate the replication-feature on the server.
Is there by any chance a way how to select the storage location for each VHD/VM if using the replication-feature of Hyper-V 2012 R2?
Thanks in advance.
Cheers,
Sebastian

Secondly, you could replicate different VMs to different storage locations to perform some of the disk balancing you are trying to perform. Lastly, you could copy the vhd file to a different location
before starting the VM.

Hi Tim,
thanks for the reply. Sorry, but I had some other tasks to take care of, so I wasn't paying enough attention to this thread.
The part I quoted from your reply sounds exactly like the action I'd like to perform, but as you pointed out before this should not be possible.
How can I perform the action (replicating each VM to a storage location) as you mentioned secondly? To sum it up again:
2x physical machines carrying severel HDDs
8+ VMs spread to run on the 2x servers
when setting up replication I can only set the storage-location from server A on B and vice versa B on A
Thanks again for your reply.
Cheers,
Sebastian

Can i add a windows 2008 domain controller in a open directory ?

i want to add an windows 2008 r2 domain controller to a open directory .
is this possible, and replicated all users to active directory?

Yes, You must establish a two-way trust between the central forest and user forests to enable distribution group expansion when groups from user forests are synchronized as contacts to the central forest.

Can account SUPPORT_388945a0 be deleted from domain controller?

Hi Guys,
I see that there have an account "SUPPORT_388945a0" has been created on domain controller automatically. Can we delete it safety?
Thanks,
OCS User

Actually that statement is incorrect. AD (or more specific the DSA/DC) can request that a set of default accounts and groups are to be created, this is for example used when you introduce a DC with a new NT version in a domain (This is independent on DFL/FFL)
their is different “default” accounts and groups defined for example Windows 2000 and Windows Server 2008 R2.
The introduced DSA with a new NT version calls the operational attribute runSamUpgradeTasks, the conditions for this operation and the accounts and groups will create in the domain are outlined here:

This can't be automatically, as there is no way AD can create account until its been automated using script or some other tools. I have seen few groups created automatically during application installation,would suggest don't delete it immediately, might
create an issue, if used for authentication as an service. Disable it & then check the impact to proceed further.

Hyper-v failed to enable replication. The virtual machine is not in a valid state to perform the operation.

I was able to replicate 2 out 5 VMs on our server but I am not sure what this error refers to. Any ideas... The VMs are up and Running
Thanks

Hi,
On the Hyper-V host server, check “Replication Health” for the VM and post the result.
Also you can use PowerShell command to check VM state and VM replication health, check that and give us feedback for further troubleshooting.
For more information please refer to following MS articles:

Can't access workstation joined to domain

I have a 2008 Server with just a few workstations attached. I turned on remote desktop on these stations and can remote to them from another workstation joined to the domain. I plugged in my laptop onto the same lan but not joined to the domain
and cannot remote to these same stations. I can remote to the server from my laptop. What is going wrong?

Hi,
What user account you used to connect to the domain joined workstations? Please try this format,
domain name/domain user account as the user account name.
Also, it can be casued by the IPSec Policy as Livi mentioned. If so, please contact your network administrator for help.
Thanks.

Can I use my Snow Leopard license in a virtual machine hosted by Mountain Lion?

If I upgrade to mountain lion, can I install snow leopard from my existing upgrade CD, purchased years ago? Need to keep snow leopard around because I'm running an app which won't run in newer OSX versions.

But they sell SL now for $19.99 at the Apple Store, and if you call Apple's phone sales team at 1.800.MYAPPLE (1.800.692.7753), you can get SL Server, also for only $19.99, so that's what I did.
We'll see how well VmWare likes it.
WOW: That is the biggest news I have heard in a long time!
I am going to call Apple and purchase a copy of SL Server for research purposes.
Also, there are some people who need access to Rosetta that just do not have the capability to use Terminal and I have always suggested that they look into acquiring SL Server (since both Parallels and VMWare allow for easier installation of SL Server).
So putting up the look and feel of SL Server may be worth the ease of installation.
This may cause me to restart an old project: extracting all of the additional frameworks that Server installs, so that it can be installed but look like and work like Snow Leopard client again
UPDATE: I just ordered my copy! Thanks!
My work here may finally be over...

Can't launch Virtual Machines in Hyper-V after sysprep on host (Server 2012)

Hi all!
I am setting up lab environments for official Microsoft Cources. I just took a new approach which is to prepare a machine with all the VMs in Hyper-V, basically I set up the whole virtual machine environment ready-to-go, then the last thing is to sysprep
the machine and then roll it out to a whole classroom.
Acording to http://support.microsoft.com/kb/2249906, this has to do with the /generalize-switch of sysprep, which is doing some spooky with SIDs that is all logical.
My question is, how can I make sure that all the VMs in the image can start up properly after the redeployment of the image?
Below is the error-msg when trying to start the virtual machine after sysprep on the host:

You should re-import the VMs on new hosts that have been deployed from a sysprepped image. This is due to the unique security GUIDs set on each VHD which can't be re-used on a duplicate host.

Time was not correct on dc which is hyper-v virtual machine

My enviroment:
1 physical server dell R720
Role: Hyper-V host
OS: Windows 2008 R2 SP1
Domain: join to domain xx.com
1 virtual machine
Role: DC+DNS+DHCP
OS: Windows 2008 R2 SP1
Domain: xx.com (olny one dc)
Located on: this hyper-v host
Issue:
I found time of virtual machine (this only one dc) was slower than current time. At that moment, time on host machine also slower, and same as dc. When I manual adjust this time to correct. It would go wrong again.
Considering time sync rule of domain and hyper-v, I just unchecked 'Time Synchoniation' on hyper-v intergrate services. Howerver time was slower again after few days.
Could it be possible wrong on hyper-v host which join to domain??
So could you give me some suggestion for this? Thanks in advance.

Hi,
You should not need to disable Hyper-V time synchronization in order to use a different time synchronization source.
" if you are running a Domain Controller inside a virtual machine I would recommend that you leave Hyper-V time synchronization enabled but that you also setup an external time source. You can do this by going to this KB article:
http://support.microsoft.com/kb/816042 and following the steps outlined in the “Configuring the Windows Time service to use an external time source” section. "
Here is a grate article about time synchronization in hyper-v :

Windows domain controller in a virtual machine: how dangerous is saving its state for a short period of time?

I have a Windows Server 2012 R2 virtualization cluster. All the hosts are connected to an external storage system, and virtual machines' files are stored on external volumes (CSVs). All the hosts and virtual machines are a part of the same AD domain
(mixed Windows Server 2012 RTM / 2008 R2 domain controllers). All the domain controllers are running in the virtual machines on the hosts of this cluster.
To prevent problems when all the hosts are turned off and then on simultaneously (for example, because of a power failure) all the domain controller VM files has been placed on local disks of the virtualization hosts (not on the Cluster Shared
Volumes). As Hyper-V services don't depend on other Windows Server services (except its networking components), it means that my domain controllers can always start, providing the virtualization host can start at all. However, it also means
that those DCs cannot be (quickly) migrated to other hosts while their current hosts are being rebooted. So if I need to reboot a virtualization host to install new updates, for example, I have to shut down the corresponding DC, reboot the host
and wait for the DC to finish cold boot and come back online. It means some interruption of service for our users, which, in turn, requires me to perform the reboots late in night.
The downtime can be significantly decreased by saving the state of the VM in which the DC is running. However, all the articles I've found on the Internet strongly recommend against it. I'm trying to understand why this recommendation was issued in the first
place. However, I'm unable to find a clear explanation. I've found some statements that saving state of a DC can cause serious AD replication problems because of tombstoning, and that the password of a DC computer account may be changed
while the DC itself stays in the saved state, which could prevent the DC from connecting to the domain after its state has been restored. However, those considerations are non-significant when we discuss a short-time
(5 to 10 minutes) saved state.
I work with AD and virtualization long time, and I fail to see any danger in saving state of a DC for several minutes. In my opinion, after its state has been restored it would simply replicate all the AD changes from other DCs, and that's all.
What's your opinion?

Hello,
as stated in "http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(v=ws.10).aspx"
Operational Considerations for Virtualized Domain Controllers
Domain controllers that are running on virtual machines have operational restrictions that do not apply to domain controllers that are running on physical machines. When you use a virtualized domain controller, there are some virtualization software features
and practices that you should not use:
Do not pause, stop, or store the
saved state of a domain controller
in a virtual machine for time periods longer than the tombstone lifetime of the forest and then resume from the paused or saved state.
This may sound as it is supported to store it for shorter times and use it.
BUT recommendation also from the Hyper-V Program manager in
http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/11/24/the-domain-controller-dilemma.aspx recommends against using them.
Also best practices

No longer able to view virtual machine from Hyper-V Manager

From the Windows 2008 R2 host machine, I can run the Hyper-V Manager and 'connect' to the Virtual Machine. The window pops up with nothing but a gray background (clearly the same gray background of the log in screen), but no 'ctrl-alt-delete' prompt
and no ability to log in. This was previously working fine.
Note that I can still make a Remote Desktop connection to the Virtual Machine and it works fine.
Thanks.

Hi,
I never seen this issue before, base on my experience, it may cause by your AV soft block some critical components of Hyper-V host, please try the following exclude specific
directories or process with your AV soft.
•Default virtual machine configuration directory (C:\ProgramData\Microsoft\Windows\Hyper-V)
•Custom virtual machine configuration directories
•Default virtual hard disk drive directory (C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks)
•Custom virtual hard disk drive directories
•Custom replication data directories, if you are using Hyper-V Replica
•Snapshot directories
•Vmms.exe (Note: This file may have to be configured as a process exclusion within the antivirus software.)
•Vmwp.exe (Note: This file may have to be configured as a process exclusion within the antivirus software.)

Integrating a Domain controller into a small office setup

So this is where I am:
I am trying to integrate a windows 2012 server which I can use as my domain controller in our office and run active directory from it, then eventually group policy, wsus, microsoft deployments and windows deployment toolkits etc.
However because our current Mitel 3300 phone system sets the phone DHCP I don't want to mess the current network arrangement up.
This is the internal structure:
Our internet router's IP address 172.16.21.1
Mitel 3300 Box IP address 192.168.10.10
Default gateway 192.168.0.1
So our IP phones sit on the subnet of 192.168.10.xxx and our PC's grab IP's such as 192.168.0.xxx up to 192.168.0.254.
What should I set my DHCP settings on the Domain controller to see the PC's on the current network, and or the DNS settings as I am fairly new to this.
If I havent explained anything properly please let me know and I will provide more info, thanks.
Jan

are all devices on the same backbone with two different subnets on it?
Are phone and computer both DHCP clients i.e. no have static addresses?
In server 2012 r2 DHCP you have the ability to rules so the phones can get ip addresses from the phone system and the computers can get ip addresses for the Domain controller.
Are you sure the phone system is DHCP for both and not your firewall? with two network adapters? or phone system one and firewall another dhcp?
typically if you phone system is giving out DHCP it would need two ip addresses and interfaces to be able to host both subnets.

Can Hyper-V host join a domain of a virtual machine domain controller on that same host?
