Ransomware Virus Help
Hey All,
Recently got it with the Ryuk Ransomware virus and potentially Cryptowall as well. Is there any piece of software out there that will assist in cleaning this mess up. Not necessarily worried about the encrypted files. But the servers are beat up from it. DHCP, DNS and so on.
Just curious and thanks in advance.....

event 81 Failover clustering
Hi,
We have a server 2019 that is also our Hyper-v Server.
This server is not part of any Cluster and Cluter manager console is also not installed on this server.
in the application log we see lots of event 81 Failover clustering-client
Why should we see this event when this server is not part of any cluster!?
Thanks

HyperV Measure-VM MeteringDuration empty
I have setup resource metering on a vm. Now whenever I run the measure-vm command against the VM, the MeteringDuration property is for the most part blank.
Sometimes the value is there in the beginning after I have reset the counters.
System is Server 2019 Datacenter HyperV

HyperV resource metering
Can anyone explain to me what the difference is between the 1 hour resource metering duration on HyperV and measure-VM is?
From what I can see measure-VM picks up resource utilization from when you enable it on the VM. If that is the case, what is the 1 hour duration on the Host?

Powershell function inside a string
This may seem strange but I am trying to store powershell functions in a SQL table.
I can do the SQL part but when I try to import the functions stored inside a string I get nothing.
For example:
$test = "function hello() { write-host ""hello world"" }"
$ps = New-Module -Name PS -ScriptBlock {$test} -AsCustomObject
$ps | gm
I get the following output:
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
No function

Virtualizing a server
Hello, Please bear with me because I am fairly new to virtualization in general.
I am attempting to virtualize a windows server 2012 r2 so that I may run it from a hyper visor host on a separate server, what is the best way to create a .vhd or .vhdx file from a live physical machine? I understand there is a tool called sysinternals disk2vhd, but this particular tool has thus far not worked for me, are there any other alternative method for accomplishing this task?

Boot to Network
We have a working USB drive. Press F12 and it will connect the machine to our SCCM server. Then you can choose an OSD task sequence to build your machine with Windows 10.
I have used a conversion tool to convert our USB drive into an .ISO. I have imported this .ISO into our Hyper-V virtual machine manager. I have built a new VM and I tell it to use the newly created .ISO.
When I boot up my VM pressing F12 does not do anything. It tries to PXE boot (even if I don't press F12) and it never connects.
How do I make F12 work in this scenario?

Port forwarding will not remain open
Synopsis:
Forwarding of port 81 to a static IP address configured in a Hyper-V Ubuntu server will not remain open.
Setup:
A Windows 10 Pro (build 18362.175) hosts a Hyper-V (100.0.18362.1) Ubuntu 18.04 server running Apache/2.4.39 listening on port 81. A Hyper-V virtual switch is configured as a wireless network adapter on the host Windows system. The Ubuntu server's Ethernet is configured with a static IP address of 192.168.222. A Netgear R6250 router is configured to forward port 81 to IP address 192.168.222:81. Appropriate server settings are set so that the host can use a web browser to view the site on the VM at 192.168.222:81.
A No-IP free ddns account is configured to forward projectmana.ddns.net http requests to the public IP address reported by its service running on the Windows system. The status of port 81 for the public IP address is checked with No-IP's port check tool (http://portchecktool.com).
Observations:
The port will not remain open. The public IP has remained constant for more than 48 hours. It is also true that no periodic refreshing (either by the router or No-IP's Windows service) is running. In short there is no evident mechanism that causes the port to be blocked. If the port is reported as blocked it can be opened by either turning on the installed No-IP Windows service or by clicking on Apply in the router's DDNS screen. Leaving either of these services on or off has no effect on whether the port becomes blocked. This suggests that neither the router or the No-IP service are responsible for the port becoming blocked while the public IP address remains constant.
The problem also occurs with port 80.

Cluster Mix (2012 and 2016) with Hyper
Hi,
after deleting the server with windows 2012 R2 from my mixed cluster with Windows 2016, I need to:
- Raise the cluster level
- Update VM Integration Services
- Update VM Versions
Is there any correct order to perform these actions?
And do I really need to perform all these steps?
Thank you.

How to remove VM if you delete the configuration file
Hi,
there are cases that we need to restore a VM that presented problem, however we do not want to lose the VM that is in trouble.
So we restore the VM with another name and this is bad for the hyperv inventory.
Is there any option that we can remove only the VM from the hyperv inventory without losing VM settings?
Thank you.

Snapshot merge process stuck on Merge in Progress (20%)
Hi guys,
On Hyper-V 2019 (which is a member of the Failover Cluster) I took a checkpoint for one of the machines.
3 hours later I deleted that checkpoint and now can see that merging process stuck on Merge in Progress (20%) and its been like this for 15-20 minutes.
However Get-VM | Get-VMSnapshot doesn't show any snapshots.
What is this and how to resolve it?
Thank you.

How manage Hyper-V from Linux?
Most my Hyper-V servers got OS Microsoft Hyper-V 2016.
For managing virtual machines i use instrument on Windows 10 MMC "Hyper-V Manager". Does microsoft give some instrument for managing virtual machines from linux. For example often i use this functionality: create, delete, export, change location, checkpoints.

Locking VM in hyperv
Hi,
Is there a way to lock/unlock the VM so that VM is not migrated in cluster environment ? In-between the lock and unlock, i like to copy the files to another system and not get impacted with migration.

Unable to start replicated virtual machine. Key protector could not be unwrapped
I have 2 virtual machines that are replicating to another Hyper-V host. One machine works and starts up fine and seems to run fine, but if I try to start my other VM it immediately come up with the error "the application encountered an error while attempting to change the state of 'server'. 'Server' failed to start. 'Server' could not initialize. The key protector could not be unwrapped. Details are included in the HostGuardianService-Client event log.
In the details section it does say local certificates not found : signing Count = 0, encrypt = 0
I am not encrypting the drives of the hyper visor or the VMs that are running below it and I am not using shielded machines. Any help would be great. Thanks

Windows 10 Pro Hyper-V Remote Management to Hyper-V on a Windows Server 2012R2
I am attempting to access a Hyper-V Management Console from a Windows 10 Pro Version 10.0.18362 Build 18362. The Hyper-V Server is running on a Window Server 2012R2. I am getting the following message when I attempt to access the Hyper-V Server from my Windows 10 Pro workstation.
The workstation and the Server are on the same domain and the Server is a domain controller. I have the domain user as a local user on the workstation and in the Hyper-V administrator group and the user is on the Server in the Hyper-V administrator group.
Looking at the Microsoft FAQ on Hyper-V the Windows 10 Pro Hyper-V MMC is backward compatable to Windows Server 2012R2.
Can anyone help with this issue or did Microsoft break this with the latest version of Windows 10 Pro.
