hi I need to create NAT network on Windows Server 2019 Hyper-V.
I following powershell steps from here:
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/setup-nat-network
1. New-VMSwitch -SwitchName "SwitchName" -SwitchType Internal
2. PS C:\> Get-NetAdapter
New-NetIPAddress -IPAddress192.168.0.1 -PrefixLength24 -InterfaceIndex24
* I insert correct InterfaceIndex from Get-NetAdapter
3. on this command I get the error and don't know what to do. Please help.
I understand that I have to assign static IP in VM without Default Gateway (?). But what the error means? What duplicate name it refers to?
New-NetNat -Name MyNATnetwork -InternalIPInterfaceAddressPrefix192.168.0.0/24
My output:
PS C:\Users\Administrator> New-NetNat -Name MyNATnetwork -InternalIPInterfaceAddressPrefix 192.168.0.0/24
New-NetNat : You were not connected because a duplicate name exists on the network. If joining a domain, go to System
in Control Panel to change the computer name and try again. If joining a workgroup, choose another workgroup name.
