I wont go into too much detail but we have been having issues when purchasing HP ProLiant Servers which were not supplied from UK market, they have leaked into the so called "grey" market and we've sent them back to the suppliers, I do have a contact at HP who checks all are purchases via the serial number - if you want his details PM me. HP are cracking down on suppliers getting kit from the grey market- the suppliers know what they are doing, there not stupid, I would advise ANYONE purchasing new HP kit (servers and networking) to get it checked out. Worst case I've heard of is HP walking in and taking the kit if its known to be HOT (aka grey market), theres nothing you can do.

New VM

I'll come back to the switching later. Try this, create a new VM in Hyper-V Manager and manually attach the VHD's to the VM - try this.

What switching you using, HP or Cisco?

We have a number of seperate vlans: Management (for Switches) Printers Wireless Servers Clients Laptops Access Control You'll need to create the vlan on the core, dhcp scopes on DC, ip helpers on the vlans etc If you need any procurve switching help let me know

Thanks - check this detailed thread out: https://social.technet.microsoft.com/Forums/windows/en-US/64aa2832-0e18-44f7-991f-a6f552046d2d/remote-desktop-connection-problem

Can you give us the error message you are getting?

iPerf I use here

All 38 schools we look after have virtual domain controllers, no need for physicals.

Can you check the logs again, also how is your switch ports setup?

why not get a proper backup solution, like a tape library for example?

Run it in elevated privileges and try again or turn UAC off

I think we need a bit more information on this, if you change the default gateway in the DHCP Settings for that scope should be good. Can we have some screenshots, wireshark logs, filtering system in use?

Great, what was the fix?

Hello, Are you doing this via the Web GUI or CLI, if you want to change the default gateway for a particular VLAN see below via CLI (example): conf t vlan 201 no ip address then input your new default gateway for your vlan: ip address 10.52.200.254 255.255.255.0 wr mem maybe do a show ip test | Manual 10.52.200.254 255.255.255.0 No

Can you see any errors or warnings at all in the logS?

PowerShell is the answer

Okay, Can you check Hyper-V logs: Finding log events for Hyper-V on Windows Server 2012 - TechRepublic

Can you check the VM you have moved has the correct NIC assigned, example:

As this isnt a Hyper-V Cluster are you just copying the VHDs or are you doing a export > import VM?

The VMs you are moving, are they on a different VLAN\Subnet? Is the networking on the switch side the same? What switches are u running?

Is AV running a scan during the backup process? What version of USB is it?
