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 again.. on a roll...

So, i have created this VM , i am having issues RDP'ing into after i changed the NetBIOS name and IP address. I get the username and password prompt but then when i punch in credentials it doesn't do anything and the prompt closes. It wont let me shut it down , comes up with error saying it may not support shutting down but i can switch it off.
Any suggestions welcome...

Hi , i just recently setup a VM guest running Server 2012 R2 - realised it only has 1 processor and wanted to allocate more. Is there a way to do this after its been built?

Good Morning Everyone,

I have a slightly unique deployment opportunity that I'm seeking some input on.  I have a client that for 2 months out of the year is a large public attraction, corn maze, pumpkin patch, zombie paintball hunting and ghost town etc...

Down time during this 8 week season is not an option.

I have migrated them to Server 2012 R2 and have done a slight bit of the pre-work for how I'd like to see this setup.  Their primary server is strong enough to run Hyper-V and at least a single virtual server.  So I have the physical machine in a standalone workgroup with the only thing being ran off that box right now one single DC in a virtual deployment.  that DC is of course 2012 R2 as well, and it also hosts quickbooks point of sale, a time clock program for employee check-in/out and also just quickbooks pro database manager.

it's a pretty small footprint, and over the last 48 hours has been running great.

I want to introduce some high-availability into this environment where the virtual will live migrate to another physical machine in a different building, but since it is a farm and there is not any existing fire suppression, I don't want all the components in the same building.  Right now two buildings are the primary and secondary network hubs (per say) as one camera server resides in a dedicated locked room with a 24 port netgear managed switch running gigabit and the other Hyper-V host server sits in the office also hooked up to a 24 port netgear…
In Hyper-V 2012R2 a guest OS is considered enlightened when integration Tools is installed. This enhances access to hardware resources, among other things. When Hyper-V is installed on Windows 2012 R2, the host OS is no longer "on the metal." Hyper-V is then underlying what earlier was the host OS, and then no longer host OS is actually a virtual machine.

My question is;
Is the host os enlightened the same way a virtual machine is with integration tools under these circumstances?

I have one physical box that is running Hyper-V and has three virtual servers running. They are all running Windows Server 2012 Standard. I am trying to get the OS that is the physical box to be able to remotely manage the other virtual servers without always having to remote connect to the virtual environment. I can see and then add the servers, but I constantly receive the error: Ensure that WinRM 3.0 is installed and enabled, all firewall ports are open. We are using AVG firewall on the virtual servers and Windows firewall on the box, because we can't seem to get the firewall service to install on the box. Below is a list of what I've tried, with the same error each time.
configure-smremoting enable all
Disable AVG Firewall
Disable Windows Firewall
Disable both Windows and AVG firewalls at the same time
Ensured that each server has a check for "Allow server to be controlled remotely"
Any and all assistance is appreciated.
I have a number of Virtual Server 2005 Virtual Machines that I need to migrate to Windows 2012 R2 Hyper V.

How do I do this ?   Issues ?

I have a small network with two file servers.  the units are identical.

Each will have server 2012 R2 standard running hyper V with two virtual servers created
One virtual server will handle roaming profiles / data storage and the other will handle exchange 2013.

Is DFS namespace a good strategy to set the units up so that if one server failed, the second one would take over and the users would not notice an interruption in service, or would there be a better way to do this

I presently work with virtualization...VMware and hyper-v, but don't deal with much security.  Can someone send some links on what I should be concerned with when it comes to virtualization and security?   .
Hi All,

I have a Windows 2012 R2 Hyper-V server with three VM’s in a four person network.  On the Hyper-V server I have one OpenVPN appliance that is almost always idle, a utility server that is also almost always completely idle, and the primary server providing file share and AD running Windows 2012 R2.

I have the following perfmon counters running on the host and primary VM:
Host drive with VM’s:
PhysicalDisk, % Disk Time
LogicalDisk, Avg. Disk Queue Length

Primary VM:
LogicalDisk, Avg. Disk Queue Length

What I am seeing is that the Avg. Disk Queue Length on the host never gets above about 0.2 while the Avg. Disk Queue Length on the VM sometimes spikes to 11.0.  

Wouldn’t it make sense that the host reading should spike to levels of at least the highest VM reading since the VM is getting the data from the host drives?  Meaning, if the VM spikes to 11.0, shouldn’t the host spike to at least 11.0?
Is there a HyperV setting that I should investigate to get the queue length lower on the VM?

hello Im about to enable DFS on a production server and set up replication to a new VM. The VM is on a VLAN locally, then after it sync's the plan is to relocate it to another site.  So far everything is setting up correctly with both servers on the namespace, etc.

Question is, one server is loaded with Data and I dont want to lose anything so going from left to right Im assuming when I get there. Left being the existing server. Any dangers with pulling the trigger on this?
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 !
