Microsoft Virtual Server

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.

Hello All,

I have two major issues with trying to implement HyperV Virtual machine over Scaled out File Server (SOFS), I would really appreciate it if anyone can help out on this.

The Setup

Scaled out File Server Name: SOFS
Test Share: \\SOFS\VM

The Issues

Creating HYPERV over SOFS Shares
- Creating a Virtual Machine on HYPERV1 from HYPERV1 does not have any issues
- Creating a Virtual machine on HYPERV2-4 from HYPERV1 result in General access denied error (0x80070005)

Quick/Live Migration over SOFS Shares
- Migration does not have any issues if I grant EVERYONE - FULL Permission to the share \\SOFS\VM
- Migration will error out in permission error if I only give FULL Permission to HYPERV1$, HYPERV2$, HYPERV3$, HYPERV4$, HOSTCLUTER$, SOFS$, SYSTEM, Administrator

I have tried other methods such as granting
Kerberos delegation
and they didn't work either. THIS IS DRIVING ME CRAZY!! PLEASE HELP!!!
Our call center is currently using a VDI environment and they want to have team viewer equivalent. Unfortunately due to the way its set up they don't know who is on which virtual desktop at which time. Are there any tools for VDI environments and call center (shadowing features) that people can recommend. Our quick fix is VNC/teamviewer on the Virtual desktops and a quick logon script that adds to a log file the user name and the hostname they use.

vCenter 5.5 - Horizion View 6.0 - View Agent 6.2 - Server 2012R2
I'm getting this error.
And when I try to power off the machine it doesn't let me because of the same message.

I try to access via console and nothing it doesn't let me enter the console same error.

So what do I do?
When I try to delete a check point I get a Error msg: Cannot delete checkpoint catastrophic error 0x8000FFFF.

Some of the checkpoints don't are missing the option of restore, export, delete.

The machine is working perfectly fine.

Look the check point got cropped.

Is it safe to delete the snapshot folder?
I have a Hyper-V host that is hosting 2 virtual machines.

One of the virtual machines is the domain controller, running DHCP and DNS

DC Static =
Default gateway is

DNS forwarders have been set-up to

The host has internet - and all the computers connected to the network have internet access - however the domain controller can't resolve IP addresses but can ping the internal network.

I have the DNS set on the VM NIC to loop back and the DG to 89.1

Am i forgetting something or have i mis configured something?
We urgently need help with file contents either corrupt or missing on certain files. We had a file server (virtual) with 2 shared drives which we had to redeploy after failure. We still have the 2 shared drives (vhdx) which we have attached to the new virtual machine. When opening certain documents we have found contents to be either corrupt or missing. Could this be due to file permissions? We have noticed that the permissions are no longer set on the files. We still have a backup of the registry key which holds the file permissions, and even after restoring the registry key, we're still experiencing the same problem. The registry key is definitely working, it is the same key we used when converting to server from physical to virtual about a month ago.
Hi All I am not able to login into any of the below
vcenter  server
vsphere client
web client

How to proceed?
Hi Experts
I cannot seem to get my head around HyperV Snap Shots.
Here is a very basic scenario,
I have a VM - VM1, current state CS1
I have 12 windows updates to install
I take a snapshot of CS1
Then I install the windows Updates
VM1 is now in new state NS1
NS1 has problems and does not boot
I know I have only two actions Apply or Delete
I want to go to CS1
What do I do?

ps: I know this is very basic, but my tests are not confirming what I watched on youtube. and I want help from Experts in here
I'm trying to configure Hyper-V on a Dell T430 using the provided virtual hard disc and virtual machine in the import wizard. prior to setting up the VM I have configured the virtual switch to use one of the two on board NIC ports. I selected external network and de-selected the option to allow the management operating system to share the network adapter. After configuring the VM I have connectivity on the Host OS but not in the VM. The error message is "not connected - No connections are available" when I hover over the network icon in the system tray.

I have verified that both Ethernet cables are good. I can connect from either NIC port (after deleting the virtual switch) from the Host OS. I have tried configuring the virtual switch on NIC 1 and NIC 2 with the same result.
I am setting up a pilot server to run remote capable virtual machines on a server. I will likely have a full blown 2012 R2 license if the project gets approval. In the mean time, I have installed the free Hyper-V server from MS and I have successfully created a VM and a Virtual switch. The VM is running according to the Get-VM. I have joined this server to the domain and it is accepting domain credentials. Here is where i am having problems: I would like to preferably use the Hyper-V manager from my Windows 10 Laptop but I keep getting the same message. "An Error occured while attempting to connect to server [servernamehere]. Check that the virtual machine management service is running and that you are authorized to connect to the server." I have researched hours and run the 2 minute fix that adds the information to the firewall. I have added my direct domain username to the Hyper-V managers and the Remote administrators group. Still get this message.

I have also tried to access the VM from the server directly but I am unsure how to do so from CMD or PS. does anyone have any suggestions?
I have a recently p2v'd Windows Server 2003 R2 vm (hyper-v) that has an important partition that is running out of space (D:) . I am looking for the best way to extend it live with out taking down the vm.  Now  I was told re-sizing via (hyper-v manager>edit disk) could lead to corruption.  I tried to extend  the partition via the unallocated space but the option is not their. Now their is enough space on the Host Server to add an additional space if needed. What would be the best route to go to safely add additional space with out risking corruption? Is it safe to convert the MBR to a dynamic disk?
Any help appreciated.


after a regular reboot of the Windows Server 2012 guest VM I am no longer able to insert any Mouse or Keyboard input into the VM, using the HyperV-Manager (tried from Win7 and WinSrv2012).
Also I cannot connect via RDP to the guest - I enter my credentials, the connection window builds up but stays black. After a timeout the windows closes again.
Fortunately I can access the server using a remote control software. In Device Manager I can see errors with mouse and keyboard.

I cannot "update" the drivers but I also cannot reinstall the integration services (Message " already installed on this machine").

All services on this server are running fine, but I cannot "access" it any regular way, not even using the hardware on the VM host.

How can I reload the drivers for mouse/keyboard or for the integration services?
Dear All,
 I have two virtual machine that keeps constantly freezing for some days, usually every second day.
Others virtual servers are fine and there are no problems.

First virtual machine is Windows 2008 server with SQL and SAP, NOD and vmtools. This machine works fine for long time. Second machine is Windows 2008 R2 with vSphere server 6, NOd and vmtools. This machine starts freezing after upgrade vSphere server 5.0 to 6.0. Both server lost ping and when I try to log in the screen freeze, so I have to make HARD RESET. If I dont login, after lost ping, I can shut down them via cmd (shutdown /r /t /m). Sometimes they are in blueScreen when they starting.

After hours of trying to figure out what could be the cause of this problem I decided to ask if anyone had an idea ? Of course I also searched intensively the web but I was unable to find any hint.

Thanks a lot in advance for any hint or help !

Thank you,

Please provide me with the steps on how to enable virtualization within the BIOS on a Latitude e6420 laptop.
When I go into the "Turn Windows features on of off" section of programs and features on a Windows 7 Enterprise OS and put a checkmark in the Windows Virtual PC selection and then click OK the virtual machine is not enabled.

This Windows 7 OS already has all of the Microsoft and Office updates installed.

I have already run the Microsoft utility and it says that this machine is capable of running virtual machines. What can I do to fix this issue so I will be able to enable virtual machines and install Windows XP Mode?
We receive this error even though we have already installed the Windows Virtual PC program, rebooted and then when we try to install Windows XP Mode we receive this error message (see the screenshot).

I have run the Microsoft hardware virtualization tool and it says that this laptop is ready for virtualization.

What can be done to fix this issue?

XP mode can't be created
I have a used Dell R515 server that has been sitting idle and want to redeploy it. I seem to recall that Dell has some sort of deployment manager where I can boot from and then specify what OS to install and also update firmware etc...

I want to install Windows 2012 and it will be used for Hyper-V role

It's been a number of years since I have done this. Any help is appretiated
Hello EE community,

Here is my problem. My Azure virtual network is set up as I need to setup VPN with corporate network, which is
Is there any way to NAT on azure side to as it relates to corporate network. My preference would be to setup Dynamic Gateway (Route-based VPN)

We usually run our VM opening first the Hyper-V Manager application, choosing the VM and clicking to open.
However, we notice a small apps titled 'Virtual Machine Connection'.  
We thought that this windows will take us straight to the VM we want but it doesn't work.

Can we use this windows to open and work with a VM?

Please advice

we are using a server 2012 running hyperV  . hyper V houses a virtual file server( FS1 ), and a virtual terminal server ( TS1 ).

We noticed that the disk space on my hyper V server had been used and there was very little left.  my tech, and I am no tech, said that for a temporary time,  I had copied a large file on to my FS1 , which allocated space from my HyperV.    and that although I deleted the file from FS1,  the hyper V server does not contract, even after the FS1 server deleted the large file

he explained it this way... it was like putting a big box on my hyper V  with data in it.  then subsequently removing the contents of the box, did not affect the fact that hyper v was still accommodating the size of that box.

sounds all good, but my hyper V C drive is a color of bright red in my file explorer and it concerns me with a relatively small amount of disk space free , at least seemingly so.

Can anyone confirm this is how it functions, and is there a type of a Defrag program which reclaims this unused space for my hyper V server ?
We have a customer on an old server but does not want to upgrade to Office 365 due to connectivity. We have used disk2vhd to convert the physical disk o vhd formats. and have created the new HyperV server on the host. The server then boots fine but due to the version of the OS we do not get a mouse. So we add the integration tools and install them OK. It then asks for a reboot

This is where the problem starts, the server boots and goes straight into a windows failed to start message stating that winboot.exe could not be found. I have googled around and have seen that I can boot with a server 2008 disk and do a rebuildbcd command.

This appeared to work as the server would now boot but after getting the windows scrolling bar that server appears to blue screen and reboots again, looping continuously.

Any ideas how to fix this, as was fine until the integration tools were installed .

I am installing Remote desktop, virtual machine based desktop deployment, on a virtual machine (Hyper-V server 2012 running on a host server 2012). I am getting an error msg “to proceed the server most have hardware-assisted virtualization”. Based on what I understand from this exchangethe role needs to be installed on the host. [Session based desktop deployment, could be installed on the VM].
Is this correct?
If yes, do I need to join the host to the domain?
I know in server 2008 is was not recommended to join the host to the domain, does this say that Microsoft feels comfortable joining the host to domain in the new version?
My impression was keeping the host for hosting only is the best practice, am I wrong with this assumption?
Have to move 4 VM's to another host to correct disk problems(bad blocks) on the RAID that stores the vhd files.  Two of the VM's have current backups while the other two (a DC and Exchange) have backups which are about 45 days old.  Was able to create a Windows backup of the Exchange database, just not the entire VM.
1) Should I rebuild a new VM from scratch to replace the DC? Have another DC in the domain.  Worried about tombstone, etc.
2) Can I restore Exchange and then try to restore the Windows backup of the mailbox database or should I also create a new VM, load Exchange and move the mailboxes?

Thanks in advance!
