Cloning Windows Server 2012 R2 Std for Tier-1 Microsoft application template ?

Hi People,
Can anyone here please suggest me what is the best way to clone Windows Server 2012 R2 Std edition to be a golden VM image or template ?
I want to use this VM image that I have created and patched so that I can deploy Tier-1 server application like : 2013 SharePoint server, Lync, Exchange Server 2013 and also domain controllers.
The Underlying Hypervisor is VMware vSphere.

Hi,
Sysprep is a commend line tool that removes unique information from your Windows installation so that you can safely reuse that image on a different computer.

Installing terminal server role on windows server 2012 to use for Windows server 2008 R2 machines.

Dear
Our current setup is as follows :-
Active Driectory is in Windows Server 2003.
Citrix Xenapp version 5.6 with all Xenapp servers in Windows Server 2003
Now we are upgrading our Citrix farm to 6.5 and all Xen app servers into Windows Server 2008R2.
We did the configuration and testing; everything works fine except the terminal server is not configured which gives the pop always for the expiry date.
We do have license for 2012 terminal server which is not possible to downgrade for some reason and managent need to install new Windows Server 2012 for terminal server and activte the licenses.
My question is :-
1 Whether Windows Server 2008 R2 will get RDS cal license from Windows Server 2012 terminal server (RDS CAL license is of windows server 2012).
2. What is the role and features I need to activate in Server 2012 in order to use for Citrix 6.5 (only applicable fetaure for getting the RDS cal license.)
3. Whether I can add this 2012 server into domain. Is it possible to add 2012 server into Windows Server 2003 AD.
Your early reply is highly appreciated.

Thanks Jeremy..
I got exactly the right answers I am lookoing for ..
I successfully activated the terminal service on the newly created Windows 2012 Server and installed the retail license pack we had of 50+50+25 keys . It later shows the 125 keys successfully applied.
when I tried to link the Xenapp (Windows Server2008R2) to the license server, it first gives me error that session host service role is not installed on the ternial server. So I installed that role also in the terminal server.
But now its anothee error as below.
RDS Cals are not available for this Remote Desktop Session host server, and licensing Diagnostic has identified licensing problems for the RD session host server.
1. Is it wrong I did by installing session host server role into the terminal server (but really it gave me error like 'session host server role is not running on the license server' when I tried to link the license server).
2. Is it the problem that Windows Server 2008 R2 will not get license from 2012 RDS CAL license.
3. whether Clearing house will take time to update the license.
Your reply is highly appreciated. I need to know whether any other way I can link the Windows Server 2008 R2 Servers (Xenapp) to the license server.

Requirement to have 3 hyper-v in Windows Server 2012 R2 Std

Hi,
I want to configure three Hyper-V in my Windows Server 2012 R2 Standard.
1. ERP System
2. Mail Server
3. AD
What requirement or license do I need to have?
Thank You.

as per my knowledge if you want to use 3 Application you can run one application on Host and other 2 Application on virtual instances.
that is not accurate.
As per MS documentation, if you run two virtual instances, the host (hypervisor) may only be used for hypervisor functions, it may not be used for applications.
http://www.microsoft.com/licensing/about-licensing/briefs/virtual-licensing.aspx
Windows Server 2012 R2 Standard
All physical processors need to be licensed. Each license covers up to two physical processors.
You may run the server software in one physical OSE and in up to two virtual OSEs for each license you assign. If you run all of the permitted instances the instance in the physical OSE can only be used to manage the virtual OSEs.

Advice on setting up a windows server 2012 domain LAB for study within Hyper V server 2012 r2 machine

HI im wanting to setup a study lab containing several windows 2012 r2 servers (mixture of core and full installs) to allow me to study towards my MCSA in server 2012 r2 and then for MCSE.
Physical equpiment,
1 pc   which is has window 8.1 pro installed from this machine. This machine i would like to remote manage and connect through to my Hyper-v server and then into any of the virtual machines. (this machine is more of a gaming pc so not
able to run to many vm's from it)
2 pc bought Just for study 8 core processor 1 tb of hhd space 16 gb of ram.
This machine i would like to setup using hyper-v server 2012 r2, which then i would create a test domain within it also with some clients allowing me to play and undstand the principles im learning.
now im getting conflictiong information regarding the Hyper-v server 2012.
If i set the hyper-v server up as a standalone in a work group. Would i be able to manage ther VM's within the hyperv server from my external windows 8 pro machine using the remote server management tools or would i need to connect that pc
to the domain.
Things I think i can do but not sure.   as im still learning
Could I setup a server 2012 r2 running AD dns and add the hyper-v role then wihtin that create the rest of the domain inside, allowing me from my other phyical machine log on to domain and manage all servers and machines.
Could I set up as i originally suggested, set up hyper-v 2012 server in a workgroup, then create the domain within the hyper-v server but still connect from my external pc to manage the hyper-v and all the internal VM's within the domain.
I could run a Domain controller on a VM from my other windows 8 machine (within hyper-v or wmware), then on the 2nd machine install the hyper-v server connect it to the domain running from the other machine from what i can see, many people say this is the
better option, BEST Practice, but this is only a lab and i dont require resilience. and i would prefer to have my  as a sever manager via the remote tools.
So what i like to know if you can point me in the right direction either by a guide for someone who has setup a similar to me.
or tell which of the above options is possible or not so i dont waste anytime.
Network, i know i can do this virtually but i already have cisco routers and layer 2 swicthes so i may make the network lab via them.
Thanks in advance for any help you can give me

"If i set the hyper-v server up as a standalone in a work group. Would i be able to manage ther VM's within the hyperv server from my external windows 8 pro machine using the remote server management tools or would i need to
connect that pc to the domain."
It makes it easier to set up if everything is in the same domain, but it is quite possible to manage the VMs without being part of the domain. A very useful tool that I use for my lab all the time (my lab is in a lab domain and my laptop is in the
corporate domain with absolutely no trusts between them) is RDCMAN.
http://www.microsoft.com/en-us/download/details.aspx?id=21101 I all my machines, physical and virtual, defined within RDCMAN and can easily connect to any one of them from my laptop. But to understand how to manage everything remotely, I create
one virtual workstation within the domain and load all the management tools on it. I RDP to the management workstation and perform most management functions, but I can get to any machine directly if I need to.
"Could I setup a server 2012 r2 running AD dns and add the hyper-v role then wihtin that create the rest of the domain inside, allowing me from my other phyical machine log on to domain and manage all servers and machines."
Yes, but you could also build the AD as a VM, too.

Install Windows Server 2012 R2 VM on Storage Spaces with Storage Tiers

Hey guys
In my small/medium sized company we will soon update to Windows Server 2012 R2. I would like to implement virtual servers using Hyper-V. I didn't find a lot of information about Hyper-V in combination with storages spaces and autoamted storage tiers.
And this is very confusing to me as it seems to me that this would be the best practice as it is the most cost-efficient and most elegant solution.
My ideal scenario:
With Hyper-V I virtualize two Windows Server 2012 R2 instances. So two separate virtual machines.
I use the following disk setup:
1x cheap HDD 40GB for hyper-v server 2012 r2 core.
2x SSD 200GB (enterprise-grade)
2x HDD 4TB (7.2k, enterprise-grade)
Step 1:
I will install Hyper-V Server 2012 R2 Core on the 40GB HDD. Via command line, I will create a storage pool with automated tiered storage using the SSDs and the HDDs in mirrored mode the following way:
With Tiered Storage, I create a storage pool containing the SSDs and the HDDs. Then I create storage space A (1TB) and B (3.2TB) with the SSDs in a mirrored setup and the HDDs in a mirrored setup. The SSDs for the „hot files“ and the HDDs for the „cold files“.
Step2:
Ontop of the storage space A I want to install the first Windows Server 2012 R2 instance with Active directory. On storage space B I want to install the second Windows Server 2012 R2 instance for a business application to run on it.
Conclusion:
The SSDs are mirrored and therefore one SSD can fail.
The 4TB HDDs are mirrored and therefore one HDD can fail.
I have a fast and easy scalable environment.
But in the Internet I found many information that it’s not possible to install an operating system onto a storage tier.
Question 1:
Is this setup possible?
Question 2:
If this setup is possible, why is not everyone doing it?
Question 3:
Is it possible to do Step 1 over a GUI from a remote machine?
Question 4:
If the creation of Storage Tiers in the Hyper-V Server 2012 R2 is not possible. Would it work to use a Windows Server 2012 R2 as a parent system on the 40GB HDD? To do Step 1?
I would gladly get some feedback of people knowing Storage Tiers well.
Thanks a lot!

I would absolutely prefer a GUI. But a Windows Server 2012 R2 Standard Licence allows you to run two VM machines.
It also grants you a physical installation ("POSE" in the licensing documents). You can buy one copy of WS2012R2 Standard, install it on the hardware, enable Hyper-V, and then operate two virtual machines with WS2012R2 Standard ("VOSE"
in the licensing documents). The only restriction is that the management operating system (POSE) can only run services and applications meant to manage the virtual machines and/or the management operating system. The Hyper-V Server license is the same way
so it's not really any different.
In short, given the benefits of the GUI at your stage of learning, you have no solid reason not to install the full system and take advantage of it. You can disable the GUI later once you get your footing. Or not. Whatever suits you. However, in response
to your Question 3, you can do this all remotely. Once you get WS2012R2 installed in a guest, you can use it to manage the management operating system if you want. There are many options.
But then I would also need to have redundancy on the 40GB HDD as if this HDD brakes, all others brake as well?
Yes, you're going to want some redundancy for the management operating system. But, you've listed 5 drives in your original layout. You don't really have a 5-bay system, do you? Is there an empty sixth bay? Could you not get two 40 GB drives instead of one
and use hardware RAID-1?

Windows Server 2012 - Hyper-V - iSCSI SAN - All Hyper-V Guests stops responding and extensive disk read/write

We have a problem with one of our deployments of Windows Server 2012 Hyper-V with a 2 node cluster connected to a iSCSI SAN.
Our setup:
Hosts - Both run Windows Server 2012 Standard and are clustered.
HP ProLiant G7, 24 GB RAM, 2 teamed NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the primary host and normaly all VMs run on this host.
HP ProLiant G5, 20 GB RAM, 1 NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the secondary host that and is intended to be used in case of failure of the primary host.
We have no antivirus on the hosts and the scheduled ShadowCopy (previous version of files) is switched of.
iSCSI SAN:
QNAP NAS TS-869 Pro, 8 INTEL SSDSA2CW160G3 160 GB i a RAID 5 with a Host Spare. 2 Teamed NIC.
Switch:
DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
Virtual Machines:
3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
1 Windows Server 2008 Standard Exchange Server.
All VMs are using dynamic disks (as recommended by Microsoft).
Updates
We have applied the most resent updates to the Hosts, WMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
Normal operation
Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with 2 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
we see speeds up to 400 Mbit/s of combined read/write for instance during file repair
Our Problem
Our problem is that for some reason all of the VMs stops responding or responds very slowly and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
Symptoms (i.e. this happens, or does not happen, at the same time)
I we look at resource monitor on the host then we see that there is often an extensive read from a VHDX of one of the VMs (40-60 Mbyte/s) and a combined write speed to many files in \HarddiskVolume5\System Volume Information\{<someguid and no file extension>}.
See iamge below.
The combined network speed to the iSCSI SAN is about 500-600 Mbit/s.
When this happens it is usually during and after a VSS ShadowCopy backup, but has also happens during hours where no backup should be running (i.e. during daytime when the backup has finished hours ago according to the log files). There is however
not that extensive writes to the backup file that is created on an external hard drive and this does not seem to happen during all backups (we have manually checked a few times, but it is hard to say since this error does not seem leave any traces in event
viewer).
We cannot find any indication that the VMs themself detect any problem and we see no increase of errors (for example storage related errors) in the eventlog inside the VMs.
The QNAP uses about 50% processing Power on all cores.
We see no dropped packets on the switch.

We have not succeeded in recreating the problem manually by, for instance, running chkdsk or defrag in VM and Hosts, copy and remove large files to VMs, running CPU and Disk intensive operations inside a VM (for instance scan and repair a database file).
Questions
Why does all VMs stop responding and why is there such intensive Read/Writes to the iSCSI SAN?
Could it be anything in our setup that cannot handle all the read/write requests? For instance the iSCSI SAN, the hosts, etc?
What can we do about this? Should we use MultiPath IO instead of NIC teaming to the SAN, limit bandwith to the SAN, etc?

Hi,
> All VMs are using dynamic disks (as recommended by Microsoft).
If this is a testing environment, it’s okay, but if this a production environment, it’s not recommended. Fixed VHDs are recommended for production instead of dynamically expanding or differencing VHDs.
Hyper-V: Dynamic virtual hard disks are not recommended for virtual machines that run server workloads in a production environment

> This is the primary host and normaly all VMs run on this host.
According to your posting, we know that you have Cluster Shared Volumes in the Hyper-V cluster, but why not distribute your VMs into two Hyper-V hosts.

> 2 teamed NIC dedicated to iSCSI storage.
Use Microsoft MultiPath IO (MPIO) to manage multiple paths to iSCSI storage. Microsoft does not support teaming on network adapters that are used to connect to iSCSI-based storage devices. (At least it’s not supported until Windows Server 2008 R2. Although
Windows Server 2012 has built-in network teaming feature, I don’t article which declare that Windows Server 2012 network teaming support iSCSI connection)

> I have seen using MPIO suggests using different subnets, is this a requirement for using MPIO
> or is this just a way to make sure that you do not run out of IP adressess?
What I found is: if it is possible, isolate the iSCSI and data networks that reside on the same switch infrastructure through the use of VLANs and separate subnets. Redundant network paths from the server to the storage system via MPIO will maximize availability
and performance. Of course you can set these two NICs in separate subnets, but I don’t think it is necessary.
> Why should it be better to not have dedicated wireing for iSCSI and Management?
It is recommended that the iSCSI SAN network be separated (logically or physically) from the data network workloads. This ‘best practice’ network configuration optimizes performance and reliability.
Check that and modify cluster configuration, monitor it and give us feedback for further troubleshooting.

Windows Server 2012 R2 - SharePoint 2013

After an front end server upgrade from Windows Server 2012 Datacenter to Windows Server 2012 R2 Datacenter of our SharePoint 2013 farm, the following error is being experienced when trying to open a document library with Windows Explorer (this
feature worked prior to the upgrade): Message from webpage "We're having a problem opening this location in File Explorer. Add this web site to your Trusted Sites list and try again."
Our domain is in the trusted sites list (*domain.com), the Webclient services are running, and the User Interfaces and Infrastructure > Desktop Experience feature is installed.
It looks like this error was previously remedied with KB2903928. This update doesn't seem to apply to Windows Server 2012 R2 Datacenter.
UPDATE: We have also discovered that site email boxes are not working.
Thank you for your assistance,
Jeanne

Hi,
Glad that the issue was solved.
Meanwhile, please understand that before the release of Microsoft SharePoint Server 2013 Service Pack 1 (SP1), Microsoft did not support the installation of SharePoint Server 2013 in a Windows Server 2012 R2-based environment.

According to the
Understanding Exchange 2007 upgrade prerequisites, https://technet.microsoft.com/en-US/Library/ee958305
these are the supported windows operating systems
64-bit edition of Windows Server 2008 Standard Service Pack 2
64-bit edition of Windows Server 2008 Enterprise Service Pack 2
64-bit edition of Windows Server 2008 Standard R2
64-bit edition of Windows Server 2008 Enterprise R2
has this list been
upgraded to include Windows server 2012 R2?? I am planning to migrate my Exchange 2007 server to 2010.
I have a downgrade license to 2008 STD R2, so i am wondering if i will have to downgrade the OS.
Thanks

SharePoint 2013 with sp1 install on windows server 2012 R2

Hi All:
excuse me I have a question about sharepoint installation. I install sharepoint 2013 with sp1 on windows server 2012 R2，but i always got "Configuring Application Server Role, Web Server (IIS) Role"
message. I refer to this article <http://support.microsoft.com/kb/2765260>. I still got this message ... Which I did wrong step ?? I have been troubled for a long time, thanks to the help ...

Hi TiM,
According to your description, my understanding is that you got an error when you installed the prerequisites for SharePoint 2013 SP1 on Windows 2012 R2.
Please make sure that you have installed .NET Framework 3.5 on Windows Server 2012 R2, and enable .NET Framework 3.5 by using the Add Roles and Features Wizard.
Here is a blog you can refer to:

Windows Server 2012 Standard - HP OfficeJet Pro 8600 Plus printer not working after promoting to Domain Controller / AD Services

An associate and myself installed the built-in drivers for the HP OfficeJet Pro 8600 Plus multi-function (network) printer on a Windows Server 2012 Standard server installation and everything worked fine whenever I want to print anything directly from the
Windows Server machine (there's a reason for this, so please understand that ;) ).
We were able to print without any problems from the Windows Server 2012 machine, using the drivers from Microsoft. Mainly, because HP has not listed any specific support for Windows Server 2012, only Windows Server 2008 R2, however, the drivers that
came with Windows 2012 seem to work very well.
PROBLEM: I later had to promote the Windows Server 2012 to a Domain Controller, and created the Active Directory configurations, even enabled the Print Services. After doing all of that, the HP printer will not print anything. It's like all print
requests directly from the Windows Server go to Nil.
Has anyone encountered a problem like this before? The only thing I can think of is that after perhaps something affected printing directly once we promoted the server to being a DC, and added other features / roles. I even tried installing the
HP drivers for Windows Server 2008 R2, and the results are still the same...nothing prints. Trust me, the printer is set as the Default Printer and even when choosing to print, we make sure the HP OfficeJet Pro is selected, and is on, as other Windows
Client PC's can print to it directly.
Does anyone have any suggestions we could try? Thanks in advance.

While it is quite a while since this was posted - I can concur a similar issue exists.
We have spent the better part of a day trying to work out why other HP printers work fine but our 8620 prints are not printing and going to Nil. The print server is hosted on a shared DC. Comparing to the initial posters details, for some reason
it seems to be most commonly related to the OfficeJet Pro 8600/8610/8620/8630 series printers.
I ended up doing a print server migration from the domain controller to stand alone host and all printers now work from a single server rather than a mix. Domain controller OSes varied from 2008, 2012, 2012 R2 (tested with multiple) and only after
all of those failed then tried a stand alone server os machine as a last resort which worked fine. Printing directly from Win 7 / 8 /8.1 clients to the IP always worked.
