Hyper link of public image(hyperlink or image) can not be saved on windows server 2012 and sharepoint 2010 problem

hyper link of public image(hyperlink or image) can not be saved on windows server 2012 and sharepoint 2010 problem, is this a bug?
thanks for any reply.

It is not a bug, you might be using IE in Windows server 2012 and and browser might be restricting your site actions to respond properly.
Check this in a different browser or access site in a differ OS.

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

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?

In my itunes tab is images / photo disappeared. . can not get it back, so now I can not get pictures on my iphone??? I do not want to use the photo stream. there are others who have experienced this tab disappears

Hi Russ, Thank you for your reply!
System Spec:
2x2.26 Ghz QUAD-CORE
12 GB RAM 1066 MHz DDR3
I've stored the library in HARD DISK which is installed inside my computer (1 TB capacity) and different from my hard disk in which I've installed all my applications (600 GB capacity).
I've installed FCP since 2001, bought FCP X in 2012: never had a problem. Yesterday I was editing my video of my last vacations (in California!) and I have updated FCP X, downloading FCP X 10.1.1: then the problem!
Strange is the fact that I've just tried to export a short project, I can see the final product quite well.
What is impossible is playing the clips within Final Cut: they are jumpimg, moving, presenting some frame in green or red ...
Everything all right in iMovie.
I've just checked the RAM: 9GB out of 12 GB is busy, could this be the problem?
Motion is very slow: for 20 sec of project, it takes minutes to play. And once again, if you finalize the projet and export it in Quicktime, you can see it correctly.
I do hope you may suggest something, I'm getting crazy!
Thank you in adavance

Bitmap image not showing up on windows title bar in windows server 2012 std

I have an application written in VC++ (MFC). Its a legacy app. Recently we were asked to check its compatibility with windows server 2012 std edition. We found some issues and one of those is as follows:
1) We display a BITMAP image using Windows.StretchBlt() function on the titlebar of the app. It shows up properly in windows server 2003, win XP and win 7. But doesn't show up in windows server 2012. I am assuming its a windows paint issue because button
is there on titlebar as I can click on it and see the expected behavior. But its just not visible.
Here is some technical workflow:
-> This function get called to paint the framwnd-
        CMainFrame::OnNcPaint()
             CMDIFrameWnd::OnNcPaint();
             // here we have code to paint the bitmap
Could anyone here please tell me why the same code is behaving differently in win server 2012? Also if there is any solution for this.

This forum is more of a general purpose forum about Windows Server. You question is more closely related to programming issues. You would be better served to post in a .NET development forum.

No. Not without access to a computer running iTunes. You do want to use your own computer so that you can restore from your backup and sync your own content back from iTunes.

Windows server 2012 File Server - Corrupt Images

Hi Guys,
I migrated a windows file share from Windows server 2003 to a new virtual windows server 2012 data centre server. All appears ok except for one issue
There are numerous word docs on this file share (over 300 pages) with images in them (jpegs,pngs ) At times when users open these docs on the new server the images in them are corrupted. When a local copy of the same file is opened all appears fine. It has
happened on a few docs now but I cant pin point why this is happening. Obviously it was not happening on the 2003 server. I have no dedup turned on or compression. I simply copied the files over and ntfs permissons. It does not happen all the time so I am
thinking it is some read/write issue in 2012. The server reports no high cpu or memory at any time.
Any thoughts on this?
Thanks

Hi. Did you ever get to the bottom of this problem?
I have the exact same issue after migrating from Server 2003 to 2012. Occasionally Office files that include images stored on the share will get corrupted with the top of some of the images showing normally and then blurring or noise in the rest of them.
I can usually restore a copy of the file made by shadow copy but the corruption of images should not be happening in the first place. Some users are losing confidence in storing their work on the share which is potentially a big issue.
I am pretty convinced that this is an issue with Server 2012 as we have not migrated from Office (2010 Enterprise) and files stores on 2003 servers on or PC hard drives are not affected.
Thanks!

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)

> 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 Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

I have racked my brain and done everything that I know to do for about two weeks now. I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
profiles. It keeps telling me that the roaming profile could not be loaded because of a slow connection. These are workstations that are connected directly to the switch that the DC is connected to. I have tried multiple connections regarding
the layout (DC into the router, router into the switch). The router is a Cisco RV220W. I have two VLANS, one for public and one for private domain. The Private VLAN has DHCP turned off since I am providing it through the DC. I currently
have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port). I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller. The DC can see
the internet fine and the workstations can connect to the shared folders on the server. I can retrieve files by just using the computer name or FQDN. The DC is also running DNS and DHCP. The DNS has the _msdcs setup from when I installed
the active directory role. I have attempted to assign static IP addresses to the workstations:
IP:                     10.0.0.80
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:        10.0.0.12
I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
The server is assigned:
IP:                     10.0.0.12
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:         10.0.0.12
The DNS entries have forwarders that forward to my ISP DNS servers for lookup
I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
I've lost my patience with this project and am sinking fast. Can someone please offer some advice as to what I've done wrong? I've created this exact scenario at work many times but, I've never done it with Windows Server 2012. Is this
possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV? I am going to attempt to work on it some more tomorrow when I get over there. I think there may be an issue with the SR-IOV not being enabled on the machine
through the Dell Bios. Would the SR-IOV really cause the workstations to report a slow connection? When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct. I don't
have "ignore slow connections" or any of those GPO's set. I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem. Any help that someone can offer, I am more than willing
to listen. If you need more information, please ask.
Thanks,
Jay

So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
Im disappointed in MS right now.

Cluster Quorum Disk failing inside Guest cluster VMs in Hyper-V Cluster using Virtual Disk Sharing Windows Server 2012 R2

Hi, I'm having a problem in a VM Guest cluster using Windows Server 2012 R2 and virtual disk sharing enabled.
It's a SQL 2012 cluster, which has around 10 vhdx disks shared this way. all the VHDX files are inside LUNs on a SAN. These LUNs are presented to all clustered members of the Windows Server 2012 R2 Hyper-V cluster, via Cluster Shared Volumes.
Yesterday happened a very strange problem, both the Quorum Disk and the DTC disks got the information completetly erased. The vhdx disks themselves where there, but the info inside was gone.
The SQL admin had to recreated both disks, but now we don't know if this issue was related to the virtualization platform or another event inside the cluster itself.
Right now I'm seen this errors on one of the VM Guest:

We don't know if this can happen again, what if this happens on disk with data?! We don't know if this is related to the virtual disk sharing technology or anything related to virtualization, but I'm asking here to find out if it is a possibility.
Any ideas are appreciated.
Thanks.

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.

Adding Hyper-V features to Windows Server 2012

I have already set up a virtual machine with Windows server 2012, when I try to add Hyper-V features it prompts error:
Hyper-V cannot be installed: The processor does not have required visualization capability.
The VM properties is:
Memory 1GB
Processor 2
Thanks to help me on this,
Zara

Confirmimg brian response, the CPU needs virtualization features for Hyper-V to be enabled.
The following link shows the hyper- V requirement for Hyper-v 2008 R2 (also true for 2012)
https://technet.microsoft.com/en-us/library/cc731898.aspx
If you want to test hyper-v inside VMs, you can download VMware workstation. There is an interesting feature (only for test purposes) that can let the vcpu inherit virtualization features, that you can enable via the VM settings. You will however notice
performances hit.

Configure Hyper V Failover Cluster on Window Server 2012 R2

I have 3 node cluster of hyper v and configured csv all machine working fine but after run backup machines get paused, so i have removed backup agent, during starting one virtual machine csv volume get un accessible and all machine pertain to that csv get
offline. subjected are the errors.
Cluster Shared Volume 'Volume2' ('Volume2') is no longer accessible from this cluster node because of error '(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.
Cluster Shared Volume 'Volume2' ('Volume2') has entered a paused state because of '(c0000015)'. All I/O will temporarily be queued until a path to the volume is reestablished.
after troubleshooting i found a patch for the related issue but its not working for window server 2012 R2,
Windows8-RT-KB2838669-x64: its not running so kindly assist how to get this fix.

Hi TFMalik,
"To avoid CSV failovers, you may have to make additional changes to the computer after you install the hotfix. For example, you may be experiencing the issue described in the "Symptoms" section because of the lack of hardware support
for Offloaded Data Transfer (ODX). This causes delays when the operating system queries for hardware support during I/O requests.
In this situation, disable ODX by changing the FilterSupportedFeaturesMode value for the storage device that does not support ODX to
1 "

Agent installation failed on chsicoecdh03.casper.com.
Fatal error during installation (0x80070643)
Recommended Action
Try the operation again. If the problem persists, install the agent locally and then add the managed computer.
==================================================================
Error on Hyper-v server:
MSI (c) (E8:D0) [16:53:24:726]: Windows Installer installed the product. Product Name: Microsoft System Center Virtual Machine Manager Agent (x64). Product Version: 3.2.7510.0. Product Language: 1033. Manufacturer: Microsoft Corporation. Installation success
