Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Are all WYSE thin clients the same.  I have upgraded the firmware of Dell WYSE ThinOS5010 to 8.6.  After the upgrade users are complaining that when they drag a document to a different location on their screen they see a ghost trail of the document being moved.  How can I tell if this is the thin client causing this or the virtual desktop.  Also are all thin clients the same, should I try purchasing a more powerful Dell WYSE Thin client.

I have an RHEL 7 running on physical server that's been fully hardened.
Would like to convert it to a VM image for use as template for future
VMs (running RHEL) rollout.

Can help provide the detailed steps involved?
Do we do P2V or we can take a backup (dd backup??) to make it to a
bootable iso?

We are using VMWare vSphere 6.5
The users in our office all access the RDS VM using a workstation. We have five licenses for the above Adobe product. For over a year I have had the email icon, which allows me attach the pdf file to an Outlook email (from O365). For reasons unknown to me, the icon is now gone and all attempts to replace it have failed.

It is checked on Show File Tools on the toolbar, and I cannot find any window which would allow me to add it. Every other user (who, of course, doesn't need it or use it) still has this email icon and email functionality.

Any suggestions as to why it is gone and how to get it back?

Of course, as I am typing this, I notice that when I click on Share on the top right I get the share column which opens when I click on the email. I can attach and email from there. It would save a step if the column was open by default.

New certificate not in use in IIS 7.
Windows Server 2012 R2 (HyperV VM in Cluster)

This is an internal site that is still working, but delivering the cert error because it is still using the old cert.

The new cert has been installed and re-installed using the GUI, PS and CMD options, but nothing seems to replace the old one.

I've cleared browser caches and reset IIS and rebooted the server many times. Nothing seems to work. I've read everything online. One blog indicated that I can replace the hash (thumbprint) in the Metabase, but I'm running IIS 7 and can't seem to find the equivalent editor to IIS 6. If I were doing this in Exchange, I would run the PS set-exchangecertificate... and replace the thumb, but I don't see an equivalent options with IIS.

There are no Proxies in use, no other hosts for this site. Internal DNS resolves directly to this machines adapter and its IP as it should. Another site on this server, also using a cert, is working fine.

Any fresh ideas would be welcome.

Hello Folks:

I have an existing Dell Wyse Environment mixed between 5070's and 5040's AIO.

I am using Dell's Wyse Management Studio v1.4 running in a VM on Server 2012.

So now down to the problem. The Dell Wyse Management Suite crashes every time the server gets rebooted or shut down. Well twice it has crashed and now this third time, (fresh install) it will work but then I properly through Windows shut down the OS and brought it back up. It is working, luckily, but suppppppper slow. Takes about 2 minutes to go between groups and/or settings in that group.

1.) Does anyone know HOW to take a back up copy of the DB?
2.) Does anyone know WHY after a fresh install then a shutdown (a perfect shutdown through Windows) now the Dell Wyse Management Suite is super slow?

A.) I cannot find any help on the web or through EE
B.) Dell won't help me, even though the software is FREE up to 10k devices which I only have about 150 devices and/or until I purchased the 10K users to go to the 'Pro' version.

I am lost and in dyer need of help. This is the 3rd time I am reinstalling the Dell Wyse Management Suite and walking around a 160k building re-validating the keys and recreating the policies!
I would like to use the esxi 6.7  free version (in a product environment) . Firstly if i use my personal email and get the serial then i can use this serial to my organization with only restrictions of the free version? or is needed to use my email from my organisation ? )  

also i plan to add a nas (synology) to the free 6.7 esxi , is this possible ? (i know that i can't use a  SAN to the free version of esxi)
what other restriction of the free version are exist?
(i plan to use a server with one cpu - 10 cores ,32 GB RAM) with 3 VMs one AD VM ,one Filse Server and one linux VM  i would like to be sychronize with azure AD and to backup also to nas (synology)

Can you see any problem to fulfill these requirements with a free version of esxi 6.7 ?
I had this question after viewing Trying to boot Virtual Machine getting "Deleted invalid filename (5) in directory -588626008".

Hi all, a few months went by and I rebooted the server after migration and got the same error.

tons of the following.
Deleted invalid filename (5) in directory -588626008

It had rebooted a few times OK, now this.

Andrew had mentioned that I should have ran an sfc on the old server first, but I got around it via finalizing the conversion, so I never did that.
hi am having this error starting my virtual box
The page says: With Converter Standalone, you can convert remote powered on machines, powered off VMware virtual machines and Hyper-V Server virtual machines.

It also says:  For information about the interoperability between vCenter Converter Standalone and powered off hosted VMware Workstation and VMware Fusion virtual machines, see VMware Product Interoperability Matrices.

I tried the "VMware Product Interoperability Matrices" at but it seems to only support Workstation 14 and up.

Does this mean I can convert via the 'remote powered on machine' method?
Im trying to install server 2016 on a VM on hyper V, without any success

VMWare Storage: VM using 4.7Tb when disks add up to 2.8Tb and there are no Snapshots. How can I find out what is using the extra disk space?
VMware Version 6.0

The VM has 5 disks total of 2.8Tb No snapshots
Provisioned storage: 5.08Tb
Used Storage 4.77Tb

Why is this so high is there some orphaned disks?
hi am not able to connect to my via ftp but i can ping my vm am using winscp my vm is in linux ubuntu my host is window 10
I have a hyper-V server running 2012 R2.  20 cores and 256 gigs RAM.  On the host is a VM (server 2016) with 8 cores and 64 gigs RAM statically assigned.  That server runs an SQL 2016 application for route automation.  The VM is five days old, just built, prepped and put into production.

There seems to be a memory problem.

Every day since install, the RAM works it's way up to 97% and the server becomes non-responsive.

Task Manager, Resource Monitor and RAM Map DO NOT show any process using this RAM.

I repeat, the process using the RAM does not show in task manager, resource monitor or RAM Map.

I'm having the dickens finding out what is eating up the RAM and need someone to make some suggestions that might help me zero in on this.

I've thought about the 2012 R2 host and the 2016 VM and maybe its a hyper-visor issue, so, anyone know any issues with 2016 running in a VM on 2012 R2?

Anyone have any software they know of that might show me where the RAM is allocated that is not showing in the programs mentioned above that I'm using?  Something other than RAM Map maybe?

Anyway, that's the ghost I'm chasing.

Thank you for any feedback you might have.
I have an 2010 Exchange system that I need to do a few things with.  One of the things I would like to do is also migrate from my old domain name to the new one, but this seems to be a task I am not 100% sure I can do and a consultant wants to charge a large sum of money to do this.

  1. Migrate to a new Domain. How hard is this and moving to O365 in a new tenant  an option?
  2. Relocate DB's to a new VMDK.  The DB's are currently on LUNS that are connected to the VM via iSCSI.  The reason I am asking this is because vCenter does not see these drives so to back this machine up I need to do it old school as if it was a physical server.  I would like to move the DB's to another drive that is a VMDK.  I have 7 DB's all around 500 GB each.
  3. Or should I do a mailbox move to new DB's located on the VMDKs?
We are trying to set up a Hyper-v VM for inside Server 2019 which will also run server 2019. Is there any guide or best practices for setting up hyper V for 2019?
Thank you
Azure Site Recovery / Zerto or Veeam?


Im investigating and testing replication of a test VM we have in azure and failing miserably.  Current production config:
  • Site to Site VPN from our on premise site(s) connected into UK South Azure region.  
  • address space.
  • All production resources (Domain controllers only so far) located here.
  • A test SQL server VM stored here and being replicated by ASR to UK West region.
  • dedicated ASR vnet used at the UKWest site.
  • A dedicated failover vnet also used for the failover replica.

I clearly must be missing something.  I have yet to failover, but understand that the replica VM can have the same IP address as before but its recommended that it doesn't (depending on the address space and subnet?

Also am i right in saying we must either add vnet peering between UK South and UK West?  A VPN connected to UK West should UK South go offline or just allow external WAN IP access?

There doesn't seem to be much simple standard information for ASR.  I was hoping this would be easy and simple.  Which leads me onto Zerto and Veeam (currently using), is anyone using this in an azure to azure setup?  If so any pointers over ASR?

I have a vm in hyper-v host that I tried to restart a service stuck in stopping mode. After waiting minutes I used task manager to kill the service. In Services.msc was still showing stopping. I then tried to restart the vm using shutdown cmd from hyper v manager. Shutting down got stuck too . After few more minutes I used Turn Off cmd in hyper-v manager. When I tried to start the machine I got the attached error. I would really appreciate any help on this, having this production vm down for a while now. Thank you,

screenshot of error

We have a 3 node cluster with shared storage, SV1, 2, and 3.

Our issue started when we were getting RPC errors when trying to connect to the cluster in failover cluster manager and other nodes hyper-v. Error is below:

"Cannot connect to the RPC service on computer "SV1". Make sure your RPC service is running."

It turned out that this issue was because the domain admin password had expired, once we changed it and logged off/on on all of the nodes the problem was fixed.


Now, when we are on SV1 we cannot create any gen. 2 VM's, but we can create gen. 1. On SV2, and 3 we are not noticing any problem. Also, we are able to create the VM if we add the ISO afterwards.

I don't think it is a problem with the storage location or the actual ISO because we are grabbing the same ISO and creating a vm no problem on the other two nodes.

Attached is the error we get when attempt to create the gen.2 VM.
Error when creating win10 VM on SV1

We also get error event [14026] in event viewer under the hyper-v server roles in custom views. Details below:

"The description for Event ID 14026 from source Microsoft-Windows-Hyper-V-VMMS cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

I am getting an 0x8024402f error on a windows 2016 server vm when trying to do a windows update.
I can download and install from the update catalog. Any help would be appreciated.

Hello guys,

Is someone able to give me a hand regarding this task?

URL lookup service

We have an HTTP proxy that is scanning traffic looking for malware
URLs. Before allowing HTTP connections to be made, this proxy asks
a service that maintains several databases of malware URLs if the
resource being requested is known to contain malware.

Write a small web service, in the language/framework your choice,
that responds to GET requests where the caller passes in a URL and
the service responds with some information about that URL. The GET
requests look like this:

GET /urlinfo/1/{hostname_and_port}/{original_path_and_query_string}

The caller wants to know if it is safe to access that URL or not.
As the implementer you get to choose the response format and
structure. These lookups are blocking users from accessing the URL
until the caller receives a response from your service.

Give some thought to the following:

* The size of the URL list could grow infinitely, how might you
scale this beyond the memory capacity of this VM? Bonus if you
implement this.

* The number of requests may exceed the capacity of this VM, how
might you solve that? Bonus if you implement this.

* What are some strategies you might use to update the service
with new URLs? Updates may be as much as 5 thousand URLs a day
with updates arriving every 10 minutes.

In VMWare 6.5, for distributed switches, in the Vmnic/uplink, how do you add a network subnet? For the life of me I don't remember (been a long time), in one of the current vmnic's i have a few networks,

What i mean is the below

and, where do i go to edit/add the networks? I did this back in 6x i believe but I no longer remember.

If core box hosts some virtual server,  the OS for the Core Box should have the same or higher OS version than that of the virtuals. Is it right?

Thank you!
