3 server in hyper-v

hi all
we need to implement in a small network 50 users (70 mailboxes) a new setup off server:
sql
exchange
AD
can It done (recommended)Although Microsoft recommendation ( NOT TO DO THIS )to hosts 3 virtual machine (exchange 2013;sql;AD). what is the risks?
thanks.

Can it be done, sure.
What are the risks, you have a single point of failure. If the VM host goes down, you lose everything. You have no backup until the host is repaired.

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.
(I have split the image to save horizontal space).
Unable to recreate the problem / find definitive trigger
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
http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx
> 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.
Use Cluster Shared Volumes in a Windows Server 2012 Failover Cluster
http://technet.microsoft.com/en-us/library/jj612868.aspx
> 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)
Understanding Requirements for Failover Clusters
http://technet.microsoft.com/en-us/library/cc771404.aspx
> 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 Hyper-V network latencies

Hi All,
I have an issue with our Windows Server 2012 Hyper-V hosts that I can't seem to figure out. Situation:
2 x Dell PowerEdge R815 servers with AMD opteron 6376 16 core CPU's and 128 GB RAM running Windows Server 2012 with Hyper-V.
2 virtual machines running on the same physical host and connected to the same virtual switch show high TCP connection latencies. One virtual machines runs a SQL Server 2012 database instance and a Dynamics AX 2012 R2 instance. The other machine a
SharePoint 2013 instance and the AX client. We see latencies of 20ms and higher on most of the TCP connections that are made from the sharepoint machine to the sql server machine.
At first I thought it might have something to do with the physical NIC's. It turned out that VMQ wasn't correctly supported by the firmware of the Broadcom BCM5709c cards. By default this setting is enabled. Turning off the VMQ setting somewhat improved
the situation but the latencies are still at 8ms and higher.
What I don't understand is what influence enabling/disabling VMQ should have on network performance. As I understand it now virtual machines connected to the same virtual switch bypass the physical altogether. Another point is that VMQ should actually improve
performance, not decrease it.
Another question I have is about the various tcp offloading settings on the physical NIC's. After installing the new firmware and drivers from Dell most of these settings are set to disabled. The documents I have been able to find talk about Windows Server
2008, any thought how these settings relate to Windows Server 2012 and whether they should be enabled?
Thanks in advance for your time and thoughts
Kind regards,
Dennes Schuitema

Hi Denes,
Please try to update your BroadCom NIC driver version ,the newest version should be 7.8.51
For details please refer to following link :

Server 2012 Hyper-V locks up Virtual Server for no reason.

Server 2012 Hyper-V locks up virtual servers for no reason.
This is a production server. I began building this server in February. I installed the server in November. 2012 server R1 is full of bugs!
First who was the rocket scientist that decided that the TURN OFF function in Hyper-V means "Please turn off when the
F*#@$*% you feel like it"? Idiots!
I have a Supermicro server with perfect memory (for those who want to blame this on memory).
It is running 12 Virtual Servers. Every morning, at a random time, at least 1 of the servers lock up solid. Sometimes as many as 5 decide that for no reason they all want to lock up. The servers that lock up may be 1 or more: a database server, a terminal
server, an exchange server, a Windows 8.1 Ent VDI server, an IIS server, and or AD server. All 2012 R1.
They are running all current Microsoft and other vendor patches and hardware updates.
The only common denominator is the Hyper-V server.
I cannot shut them down using the Hyper-V manager. I cannot turn them off. I have a hundred users standing by while I nicely ask them to turn off. The VM will turn off after 20 minutes and a lot of gentle coaxing.
I cannot Kill the vmwp.exe process associated with the locked Virtual Machine.
No .DMP are created. No events in the event viewers. No reason at all. When they restart, there is no indication of a problem.
I ran two VMWP dumps and posted it here.
www.a1bcs.com/hyper-vlockup.zipx
Does anyone know why these are locking up?
Thanks in advance for any help.
Robert

I'm not positive of the cause but I was able to stop the problems.
It turned out that Network Load Balancing (NLB) between the two terminal servers and another between the two gateways was causing the lockups.
This is a normal configuration and it should work. Especially since Microsoft has seen fit to remove the DRAIN USERS function from RDP as well as the LOCK OUT till next reboot function. JUST FYI these functions are still available at a DOS prompt
by using the CHGLOGON command. But still the NLB also provides these functions.
Anyhow, once I removed the NLB I haven't had the lockups anymore.
That doesn't however change the fact that TURN OFF should mean TURN OFF not turn off please!
Thanks again,
Robert

Windows Server 2012 - Hyper-V - Cluster Sharded Storage - VHDX unexpectedly gets copied to System Volume Information by "System", Virtual Machines stops respondig

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. This is the primary host and normaly all VMs run on this host.
HP ProLiant G5, 20 GB RAM. 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 off.
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, VMs 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 two 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 a random VHDX gets copied to System Volume Information by "System" of the Clusterd Shared Storage (i.e. C:\ClusterStorage\Volume1\System Volume Information).
All VMs stops responding or responds very slowly during this copy process 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.
This happens at random and not every day and different VHDX files from different VMs gets copied each time. Some time it happens during daytime wich causes a lot of problems, especially when a 200 GB file gets copied (which take a lot of time).
What it is not:
We thought that this was connected to the backup, but the backup had finished 3 hours before the last time this happended and the backup never uses any of the files in System Volume Information so it is not the backup.
An observation:
When this happend today I switched on ShadowCopy (previous files) and set it to only to use 320 MB of storage and then the Copy Process stopped and the virtual Machines started responding again. This could be unrelated since there is no way to see
how much of the VHDX that is left to be copied, so it might have been finished at the same time as I enabled ShadowCopy (previos files).
Our question:
Why is a VHDX copied to System Volume Information when scheduled ShadowCopy (previous version of files) is switched off? As far as I know, nothing should be copied to this folder when this functionis switched off?

Please note:
Please only answer our question and do not offer any general optimization tips that do not directly adress the issue! We want the problem to go away, not to finish a bit faster!

Hallo Lawrence!
Thankyou for youre reply, some comments to help you and others who read this thread:
First of all, we use Windows Server 2012 and the VHDX as I wrote in the headline and in the text in my post. We have not had this problem in similar setups with Windows Server 2008 R2, so the problem seem to be introduced in Windows Server 2012.
These posts that you refer to seem to be outdated and/or do not apply to our configuration:
The post about Dynamic Disks:
http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx is only a recommendation for Windows Server 2008 R2 and the VHD format. Dynamic VHDX is indeed recommended by Microsoft when using Windows Server 2012 (please look in the optimization guide
for Windows Server 2012).
Infact, if we use fixed VHDX then we would have a bigger problem since fixed VHDX are generaly larger then Dynamic Disks, i.e. more data would be copied and that would take longer time = the VMs would be unresponsive for a longer time.
The post "What's the deal with the System Volume Information folder"
http://blogs.msdn.com/b/oldnewthing/archive/2003/11/20/55764.aspx is for Windows XP / Windows Server 2003 and some things has changed since then. for instance In Windows Server 2012, Shadow Copies cannot be controlled by going to Control panel -> System.
Instead you right-click on a Drive (i.e. a Volume, for instance the C drive/Volume) in Computer and then click "Configure Shadow Copies".
Windows Server 2008 R2 Backup problem
http://social.technet.microsoft.com/Forums/en/windowsbackup/thread/0fc53adb-477d-425b-8c99-ad006e132336 - This post is about the Antivirus software trying to scan files used during backup that exists in the System Volume Information folder and we do not
have any antivirus software installed on our hosts as I stated in my post.
Comment that might help us:
So according to “System Volume Information” definition, the operation you mentioned is Volume Shadow Copy. Check event viewer to find Volume Shadow Copy related event logs and post them.
Why?
Furhter investigation suggests that a volume shadow copy is somehow created even though the Schedule for Shadows Copies is turned off for all drives. This happens at random and we have not found any pattern. Yesterday this operation took almost all available
disk space (over 200 GB), but all the disk space was released when I turned on scheduled Shadow Copies for the CSV.
I therefore draw these conclusions:
The CSV Volume has about 600 GB of disk space and since Volume Shadows Copy used 200 GB, or about 33% of the disk space, and the default limit is 10% then I conclude that for some reason the unscheduled Volume Shadow Copy did not have any limit (or ignored
the limit).
When I turned on the Schedule I also change the limit to the minimum amount which is 320 MB and this is probably what released the disk space. That is, the unscheduled Volume Shadow Copy operation was aborted and it adhered to the limit and deleted the
Volume Shadow Copy it had taken.
I have also set the limit for Volume Shadow Copies for all other volumes to 320 MB by using the "Configure Shadow Copies" Window that you open by right clicking on a drive (volume) in Computer and then selecting "Configure Shadow Copies...".
It is important to note that setting a limit for Shadow Copy Storage, and disabaling the Schedule are two different things! It is possible to have unlimited storage for Shadow Copies when the Schedule is disabled, however I do not know if this was the case
Before I enabled Shadow Copies on the CSV since I did not look for this.
I now have defined a limit for Shadow Copy Storage to 320 MB on all drives and then no VHDX should be copied to System Volume Information since they are all larger than 320 MB.
Does this sound about right or am I drawing the wrong conclusions?

There is something strange about the limits on the Secondary host!
I have not in any way changed the settings on the Secondary host and as you can see, the Secondary host has a maximum limit of only 35 MB storage on the CSV, but it also shows that this is 10% of the Volume. This is clearly not the case since 10% if 600
GB = 60 GB!
The question is, why does it by default set a too small limit (i.e. < 320 MB) on the CSV and is this the cause of the problem? I.e. is the limit ignored since it is smaller than the smallest amount you can provide using the GUI?
Is the default 35 MB maximum Shadow Copy limit a bug, or is there any logical reason for setting a limit that according to the GUI is too small?

Hello,
I have setup server 2012R2 Hyper-V. I have 2TB physical HD and partition the C drive to 300GB and the rest,1.5Tb, for my DATA. 1. How do I use Powershell to initialize the 1.5Tb, format to NTFS and assign drive letter?
I am able to remote into the Hyper-V using remote desktop. When connect to the server using Hyper-V Manager, I got the following error "Operation on computer failed"10.10.10.10".
2. How do I enable the RPC using powershell?
veasna

Hello veasna,
to 2:) is your Server Domain based? If so, then RPC communication should work out of the box. If not then you can use to configure the Client and Server the tool
hvremote. The link contains as proper documentation as well.
to 1:) YOu can connect to the Server and start a local Powershell. Then follow the guidance in this
article.
Hope this helps
Kind Regards
Thomas

Server 2012R2 Hyper-V Are the VDI machines of a collection always running

Hello
I got a Windows Server 2012r2 Hyper-V Cluster to run Windows 8.1 Guests on.
If I create the collection with 10 Guests, are these machines always running?
Or can I configure that only two machines are running and always when a user is connecting to a running guest, one more guest is started up to be ready for the next user?
Thanks for your answer,
Juerg

Hi,
Thank you for posting in Windows Server Forum.
In respect to your comment, I can say that you have Hyper-v cluster to run windows machine. As per my knowledge, cluster won’t shut down or power off. If we use PS to shut down our VDI, we need ask the helpdesk to startup our VDI manually, so the VM in VDI
must always running. As all know, there are many servers are running under single cluster, so if one fail, all the application will up on others servers, but the application can close by its admin, cluster cannot control this operation.
Based on my knowledge, for your other comment “one more guest is started up to be ready for the next user?” VDI admin need start up this VDI manually and there is no any option or feature which can ready the VM to be used by other users.
Hope it helps to understand!
Thanks.

2003 Server in Hyper V

Good Morning,
I have a 2008 server and I am running HYPER V with a virtualized 2008 server and I am also trying to virtualize a 2003 server. I have installed the 2003 server but I cant get the mouse to work. Hyper v is telling me to install the integration services which I try and do and then I get an error saying that "an error has occured the specified program requires a newer version of windows."
Am i able to install a 2003 virtualized server on a 2008 server running hyper V?

Yep, Brian's on point with this one
You'll need to make sure you're running the Release version of Hyper-V by downloading the RTM Update
950050 Description of the update for the release version of the Hyper-V technology for Windows Server 2008
http://support.microsoft.com/default.aspx?scid=kb;EN-US;950050
The VMs that you have configured now may not work after you update to RTM. If you cannot start them after you update, read this article:
949222 Virtual machines that were created on the beta version of the Hyper-V role do not start after the Hyper-V role is updated to a later version
http://support.microsoft.com/default.aspx?scid=kb;EN-US;949222
Now, in regard to the message you're seeing when you attempt to install the ICs. Windows 2003 requires Service Pack 2 before the Integration Services will install. Download it here http://technet.microsoft.com/en-us/windowsserver/bb229701.aspx and then install it and the ICs will install just fine.
=============================
In regard to the error about the patch not applying to your system, verify wether or not it's already installed.
Go to Programs and Features in the Control Panel, then select 'Show installed Updates' in the upper left hand corner, and look for (KB950050) - it should be toward the bottom if not the actual last update listed.
If you have it there then the message is right - it doesn't apply. Then all you'd need to do is install Sp2 for 2003 and you'll be good to go for installing the Integration Services.

Crystal Reports XI R2 and Window Server 2008 Hyper-V environment

Hello,
Is there any known issue that Crystal Reports XI R2 running on Window Server 2008 Hyper-V enviroment?
I tested on Development Server which is Window Server 2008 and it is working fine but when tested with another servers which are in Hyper-V enviroment and ASP.NET program keep crushing.
I got the below error on my event log:
Faulting application w3wp.exe, version 7.0.6002.18005, time stamp 0x49e023cf, faulting module unknown, version 0.0.0.0, time stamp 0x00000000, exception code 0xc0000005, fault offset 0x03976ce8, process id 0x%9, application start time 0x%10.
Thanks,
Yin

Hi Yin,
Hyper-V I assume is the Hyper threading Intel and others enabled correct? Should not make a difference other than performance. You are still using 1 CPU so the cycles are being split between multiple programs. Not really an advantage.
Try using ProcessMonitor and search on access denied to see what is having the problem.
Other issue is CR XI R2 is not supported on windows 2008, or at least you should be running Service Pack 6 to at least get Windows 7 and Vista support, which is about the same as Windows 2008.
Go to our download page and install SP 4 full build and then SP 6. ( assuming you don't have any SP's installed ) or look in the download area and download all of the patches from SP 4 as well as the distribution files for how ever you are deploying your application.
Thank you
Don

Hyper V manager on 2008 R2 connect to 2012 R2 server core hyper V without domain

Dear all
I am using Hyper V manager on 2008 R2.
Now I have one 2012 R2 server core hyper V without domain, I want to manage this server core hyper V with Hyper V manager on 2008 R2.
When I add/connect, it display credential wrong. (use command net use drive works)
May I know is it a must to join domain?
thx
Q K

You're saying you want to use Hyper-V Manager on 2008R2 to manage 2012R2 Hyper-V, correct? If so, unfortunately this is by design:
http://blogs.msdn.com/b/virtual_pc_guy/archive/2012/05/30/the-v2-wmi-namespace-in-hyper-v-on-windows-8.aspx
You'll have to use the built-in tools in Windows 8.1 to manage 2012 R2 Hyper-V remotely. Here's the support matrix:

New Windows server 2003 Hyper-V guest fails to boot

Hello,
I'm currently doing some virtualization experiments on my new server hardware. The host hardware is:
IBM x3650 M4
x2 Xeon E5-2609
32GB RAM
x2 480 GB SSDs
Server OS: Windows server 2012
I'd like to test some legacy app virtualization. I've configured a VM and have installed Windows server 2003. The install is done via DVD. The issue at hand is that after the initial installation, the server fails to boot. The VM goes into a reboot loop
and so far the only error logging I'm able to find is in the hosts event log.

If its relevant, the host is not yet activated license wise. I downloaded the demo version so I could test my idea before making a purchase to go ahead with full implementation.
As it stands right now I'm not sure how to troubleshoot this. Many searches on google have not turned up any helpful info. Does anyone have any ideas?
Thanks,

Hi ,
First , please refer to the supported guest OS of windows 2012 hyper-v :
http://technet.microsoft.com/library/hh831531.aspx
2003/R2 should be with sp2 and max 2 virtual processors .
"'LegacyTS' was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault."
If the issue is not due to the above items , you can try to check the "CPU compatibility " in that VM settings for troubleshooting:
Hope it helps

Server 2008 Hyper-V Failover Cluster Error on Domain Controller Reboot

I am pretty new to Hyper-V virtual but I have 2 Hyper-V Clusters, each with 2 Nodes and a SAN, 1 Physical Domain Controller for failover cluster management and 1 virtual domain controller as backup. All is running well, no issues. I installed
windows updates on the physical DC and upon reboot, got an error 5120 on cluster 2 that says "Cluster Shared Volume 'Volume1' ('Cluster Disk 1') is no longer available on this node because of 'STATUS_CONNECTION_DISCONNECTED(c000020c)'. All I/O will
temporarily be queued until a path to the volume is reestablished. It pointed to the 2nd node in that cluster as being the issue but when I look at it, it is online and all healthy so I don't understand why the error was triggered and if the DC would
go down for a failure, would that node not be able to access the CSV permanently.
Appreciate any help anyone can provide.

Hi mtnbikediver,
In theory, if you has the correct configuration of cluster the DC restart will not cause the CSV down, does your shared storage installed on your DC? Did you run
the cluster validation before you install the cluster? We strongly recommend you run the cluster validation before you build the cluster, same time please install the recommend update of 2008 cluster first.

http://support.microsoft.com/kb/957311
I found a similar scenario issue the DC restart will effect the cluster network name resource offline, but it is for 2008R2.
Cluster network name resource cannot be brought online when one of the domain controllers is partly down in Windows Server 2008 R2

I’m glad to be of help to you!

Exchange Server 2013 Hyper-V vs Physical Server & SMB3.0 vs SAN

Looking for advise on installing Exchange Server 2013 in a virtual (Hyper-V) environment or dedicated physical server installation. Also, when setting up the data storage, what's the best practices for using SMB3.0 vs direct storage SAN. We're
leaning to shared storage using SMB3.0 rather the SAN (very costly) and can use a dedicated 2012 Server with 4TB of storage (RAID 10) with (shares).
Thank you,
William

Have you tried Storage Calculator? search it on TechNet site an input the values .. If you want me to give your the specs then I'd ask
Total Send/Receive Capability / Mailbox / Day
Average Message Size (KB)
Mailbox Size Limit (MB)
Personal Archive Mailbox Size Limit (MB
If you already have an existing Exchange 2010/2007 then you can also calculate the above input.
Let me know ..

0x80070569 Error When Creating Second Virtual server in Hyper-v 2012

I get this error when I try to create a second VM from Hyper-v Manager on windows 8 / server 2012 / server 2008 R2.
Hyper-v is running on a new install of server 2012 core.
I was able to create the first VM (server 2012 with a GUI) and is running fine.
I have tried adding the local administrator account to the logon as a batch job and doing a gpupdate /force with not luck.
Both the server 2012 core and the server 2012 VM are joined to the same domain. I am logged into server 2012 and server 2008 R2 as the domain administrator.
Any ideas would help!

Hi,
Error Message: The user has not been granted the requested logon type at this computer, this problem typically occurs when the user does not have the permissions to log on locally on the computer.
By default, members of the Users group have the ability to log on locally, but an administrator can deny the right to specific user or group accounts. An explicitly denied right always overrides an allowed right.
This can be caused by either of the following:
Neither the user account nor any of the groups it belongs to has been granted the Allow log on locally user right.
The user account or one or more of the groups it is a member of has been listed in the Deny log on locally user right.
Ensure that the user, or a group the user belongs to has the right to log on locally. Ensure that the user, and all groups that the user belongs to, are not denied the right to log on locally.
Also, have you tied to restart to restart the Hyper-V host server? Restart it and check the result.
You may also try to create VM using PowerShell command:

Backup active directory server in hyper-v (copying vhdx)

We want to add 2nd AD in our network(about 45+ user) and thinking putting it in a hyper-v server. Just wondering if the hyper-v host are die is it possible to copy the vdhx of the 2nd AD and move it into another host to run. Have anyone have any experience
on it , thanks?

Hi Sir,
>> Just wondering if the hyper-v host are die is it possible to copy the vdhx of the 2nd AD and move it into another host to run.
Yes ,you can copy the VHDX file to another hyper-v host then create new VM attach this VHDX .
After the new VM starts-up , If the VM's IP is configured to static in original hyper-v host then you may need to delete the original NIC information ,please refer to following registry path (delete the NIC under Interfaces which has the
old static IP address ):
Then you can configure original IP address for the new virtual machine .
