Windows Server 2012 Virtual Machine Failure

I am running Windows Server 2012 R2 Host machine. In Hyper-V, I created a WS 2012 VM. The VM starts out OK, but after a few hours of work (configure and install SharePoint 2013), starts throwing errors (Machine had to re-boot). Eventually, the VM becomes
unstable and unable to re-boot. Last attempt threw this error in Hyper-V Event Manager:
'BISP2013' has encountered a fatal error. The guest operating system reported that it failed with the following error codes: ErrorCode0: 0x7A, ErrorCode1: 0x400207A0, ErrorCode2: 0xC0000185, ErrorCode3: 0x57BA6860, ErrorCode4: 0x40F4234. If the
problem persists, contact Product Support for the guest operating system. (Virtual machine ID 7E140D89-25B9-4D3B-835B-7BB882C629BB)
This has happened on multiple attempts occasionally ending with Error 0Xc000021a. Creating WS 2012 R2 VMs does not present this problem.
Any suggestions greatly appreciated.

Hi Mario,
This should not happen here .
My suggestion is to download a new server2012 ISO and reinstall .
Also please refer to following "best practice configurations for sharepoint 2013":

Hyper-V host fails with "RPC Server unavailable" error when I try to promote Windows Server in virtual machine to a domain controller

Host: Windows Server 2012 R2 with Hyper-V and RRAS (for Internet over NAT)
VM: Windows Server 2012 R2 with installed Active Directory Domain Services
When I open AD DS configuration window (“promote this server to a domain controller”) many services and programs on my host (include Hyper-V, RRAS & Server Manager) fails with RPC Server unavailable error.

Hello Aleksandr,
There wasn't any configuration information, ipconfig /all, network setup, etc. So it's difficult to tell.
More importantly, are you trying to promote the host server? If yes, that is not advised, for one, because it's a Hyper-V server, (not suggested at all), and two, RRAS is installed. RRAS is problematic with any domain controller because it turns it into
a multihomed domain controller.

Networking?
I don't know how your networking is setup, whether there are multiple NICs on the host server, if they are teamed, if you have the host interface set to allow the operating system to share administration, or if there are separate interfaces for each. Can
the host OS ping/communicate with the DC virtual machine?
If there are more than one NIC, you have the choice to team the NICs and share the Teamed NICs for the Hyper-V OS and the VMs, or keep them separate where one is devoted for the Hyper-V OS, and one for the VMs.

Error when creating a database on SQL Server 2012(Virtual Machine)

Hi,
I create a virtual machine on VMWare Workstation 10, then install Windows 7(32bit), then install SQL Server 2012 Enterprise version.
Then I write a Visual C++2008 program and using ADO to connect to the local SQL Server, with the connection string below:
“Provider=sqloledb;Data Source=(local);Integrated Security=SSPI;”
The connect succeed, then I try to create a new SQL Server database by calling:
m_pConnection->Execute(_T(“create database MyDatabase on primary (name = ‘MyDatabase’, filename = ‘E:\\MyDatabase.mdf’)”), NULL, 0);
where E: is a USB drive plugged in.
When running the above statement, I can even see the MyDatabase.mdf file is being created, but finally get an error and error number is 80040e31 when checking the error from m_pConnection, after analyzing the com exception, we find it reports the error as
“IDispath error #3121”. Both errors seem to indicate a “Timeout error”.
Then I try to create the database on the local drive in the virtual machine, as follows:
m_pConnection->Execute(_T(“create database MyDatabase on primary (name = ‘MyDatabase’, filename = ‘C:\\MyDatabase.mdf’)”), NULL, 0);
Then I get error number: 80040e14 from m_pConnection, and com error is “IDispath error #3092”
What is the problem?
Thanks

TS 140 Windows Server 2012 R2 install failure error 0x80070570

Recently bought 2 TS140 70A4001PUX servers with Xeon E3 1245 v3 attempting to install eval version of server 2012 R2 (latest on site April refresh) and keep getting the following error at around 62% in the getting files ready for installation:
Windows can not install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070570
I have seen web search results for various MS OSes that indicate this is due to bad memory, corrupt installation media or download, Nic cards, BIOS settings etc.
To rule out memory ran memtest for hours with no errors against the crucial 32GB mem 2 (CT2KIT102472BD160B) also tried installing against the 4GB mem that came with the system. I think I have done enough to rule out the memory.
Installation media, I downloaded the ISO from Microsoft's eval site three different times using Firefox, Chrome and IE burned the image to DVD 2 different times and tried numerous times using Rufus on an 8GB USB stick in different USB ports. I’ve tried installing the datacenter version with both GUI and server core options. Next thing I’m going to try is to install Server 2012 from an older ISO that I have used successfully many times in the past will update later though I would prefer to install fresh from R2.
I also have the Lenovo 1GBPS Ethernet I350-T2 Server adapter by Intel for ThinkServer. I have tried installing with it inserted and with it removed, also with nothing even disabling the on board Nic in the BIOS. Same result.
The SSD drive I have is the Samsung 850 Pro 128GB. After the failure I am able to mount this drive on another machine and see that a significant amount of files get copied to it so I ruled out the sata cable. I also tried with another no SSD WD HD with the same result. I even break out at install run dispart and clean the partitions.
Excerpts from setupact.log on SSD:
2015-03-24 13:58:37, Info       [0x0606cc] IBS   Calling WIMApplyImage (flags = 0x180)...

For BIOS settings I have reverted back to defaults tried IDE instead of AHCI and also tried CSM support enabled and disabled, NIC both enabled disabled.
Any suggestions would greatly be appreciated.
Thanks.
Solved!
Go to Solution.

In case anyone is interested the Server 2012 R@ eval ISO I had issues with is the following file:
9600.17050.WINBLUE_REFRESH.140317-1640_X64FRE_SERVER_EVAL_EN-US-IR3_SSS_X64FREE_EN-US_DV9.ISO
I am also reporting this to MS.

Hi Krishna,
Thank you for posting in Windows Server Forum.
When you are configuring RDVH initially, please see that you have meet prerequisites. Remember that you need these pre-requirements:
• Database based on SQL Server 2008 R2
• Static IP Address for all Broker
• Round Robin DNS
• All RD Broker must be members of AD Windows Group (es. RDCB Server Group)
• The group must be insert into SQL Server as sysadmin ONLY for the DB creation. After that DB will be created give the db_owner permission only for their DB
More information.
Windows Server 2012 R2: Unable Add New VDI Template
In addition, we need all RD Broker must have the same SQL Native Client as main SQL Server (es. SQL Server 2012 SP1). The Connection Broker server's computer account MUST be a member of the local administrators group on the Virtual Host (RDS Host) machine and
then reboot the server. Finally check the result.

I uninstalled all machines and VMware entirely, reinstalled VMware and then reinstalled machines, went though the guide again, same error when trying to connect the app server to the contoso.com domain.
Here's a screenshot of the error:
I also tried changing both machines to bridged connection, no luck, as well as NAT connection, still no luck.
Any help is greatly appreciated... Thanks guys!

MCSA Windows Server 2012 Certification Exam prep

I am studying for the MCSA Windows Server 2012 certification. I have looked at the books on amazon and would like your opinion on book selection. In the past I have found the self-pace exam prep books by microsoft to my liking. If you know of any
web sites that contain information on how to prepare for the MCSA Windows Server 2012 certification that would great too. I think I am going to setup a lab using Windows Server 2012 R2 machines to assist my learning so information on that topic would be great.
I am currently using Virtual Box to create virtual machines.

Hi, I always liked the exam prep book from MS with hand-on lab. There is
http://www.microsoftvirtualacademy.com/ from MS as well, could be a good place to check. I know too that @KeithMayer on twitter do post a lot of ressource too.
I will move the thread to the learning section, as maybe other users got other ressource of value.

Report Viewer control issue in Windows Server 2012 R2

Hi,
I have a reporting application (web) and it is using the Microsoft.ReportViewer.WebForms.dll (version 11.0.3366). While deploying I have kept all the Reporting Viewer related dll's into the bin directory and things are working fine in the below combinations.
1) Windows Server 2008 R2 , SQL Server 2008 R2 SP2
2) Windows Server 2012 and SQL Server 2012
Today I have installed the same setup into the Windows Server 2012 R2 (with SqlServer 2012) machine and I am facing the some issue. The Print icon and find/next options are not visible in the Report Viewer . I am not sure what was the cause for this.
Then I have installed the Report Viewer 2012 runtime on the Windows Server 2012 R2 machine and things are working fine. So , I am wondering how the same setup worked fine in other two combinations with out installing Report Viewer 2012 runtime.
Did any one have idea/suggestion on this.
Thanks in advance!
Best Regards
Muthuraja

Have you verified that the runtime assemblies are not on those servers? Maybe someone else added them. There are numerous other possibilities such as code refactoring that moved these elements from to other assemblies (unlikely) or that there was some other
difference in your installation that you overlooked. I am glad that you were quickly able to resolve your issue however and may help others if they experience the same problem.

Re-use Hyper V VM built in Windows Server 2008 R2 host in a new Windows Server 2012 host

Hi Forum members,
I was assigned a Windows Server 2008 R2 host machine with Hyper-V which I used to build many VM's for testing. This host machine now is going to be replaced with a new Windows Server 2012 host machine. Is it possible for me to continue
to use those VM's without any migration (e.g. is it possible to import or simply move the *.vhd + *.avhd files from the 2008 Server to 2012 Server and use them)?
Thanks and Regards,
Hien

That is the official statement of 'support'
They will run, and you may need to do some custom configuration (such as using a legacy nic) but you can't call MSFT support and say your Server 2003 VM is broken on Hyper-V 2012 R2
The act of importing the configuration and linking to the VHD and snapshots will work.
The act of booting the VM and having the OS in the VM 100% happy is not automatic, but should work.
It becomes a question of where do you place the risk.

Provisioning Windows Server 2012 R2 takes long time

I created a simple bluerpint with one Windows Server 2012 R2 machine and using Linked Clone deployment in vCAC. The entire provisioning process is taking a very long time (> 1 hour). It looks like most of the time is spent in CustomizeOS work flow step. What could be the issue? I didn't find any logs to figure out where it's spending time. Can you help me fix this issue?

I was able to fix this issue. There is a new Guest Agent for Windows Server 2012 R2. See VCAC 6.0.1 Windows 2012 guest agent stuck

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 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?
