Windows Server 2012 Server Core–Playing with Network Card using PowerShell Part 2

Setting DNS server First find the InterfaceAlias or InterfaceIndex using the “Get-NetIPInterface” of the desired interface. Now use the following command to set the DNS server IP address
Set-DNSClientServerAddress –InterfaceIndex <InterfaceIndex as UInt32> -ServerAddresses <Comma separated list of IP Address as String>
                                                                 or
Set-DNSClientServerAddress -InterfaceAlias <InterfaceAlias as String> -ServerAddresses <Comma separated list of IP Address as String>
Before Setting DNS
  After Setting DNS
Removing DNS server First find the InterfaceAlias or InterfaceIndex using the “Get-NetIPInterface” of the desired interface. Now use the following command to reset the DNS server IP address
Set-DnsClientServerAddress –InterfaceIndex <InterfaceIndex as UInt32> -ResetServerAddresses
                                       or
Set-DnsClientServerAddress -InterfaceAlias <InterfaceAlias as String> –ResetServerAddresses
After resetting DNS
Removing IP Address First find the InterfaceAlias or InterfaceIndex using the “Get-NetIPInterface” of the desired interface. Now use the following command to remove just the IP address from the interface
Remove-NetIPAddress –InterfaceIndex <InterfaceIndex as UInt32>
                                 or
Remove-NetIPAddress -InterfaceAlias <InterfaceAlias as String>
 If you want to remove the IPAddress without confirmation just use the option “-Confirm:$false” at the end of above command, of course without quotes. Now if you want to remove IPAddress and default gateway then use the following command. Use “-Confirm:$false” part only if you don't want questions for confirmation.
Remove-NetIPAddress –InterfaceIndex <InterfaceIndex as UInt32> -IPAddress <IPAddress as String> -DefaultGateway <DefaultGateway as String> [-Confirm:$false]
                                                                       or
Remove-NetIPAddress -InterfaceAlias <InterfaceAlias as String> -IPAddress <IPAddress as String> -DefaultGateway <DefaultGateway as String> [-Confirm:$false]
 Viewing DNS cache Use the following command to view the DNS cache
Get-DNSClientCache
 Clearing DNS Cache Use the following command to clear the DNS Cache
Clear-DNSClientCache

Windows Server 2012 Server Core–Playing with Network Card using PowerShell Part 1

Finding the InterfaceIndex or InterfaceAlias of the network adapters in the system
Get-NetIPInterface
This will list all the Network cards with their InterfaceIndex, Interface lias, AddressFamily, NlMtu in Bytes, InterfaceMetric, DHCP status, ConnectionState and PolicyStore in that order.
To view more details about a particular network card use the following command
Get-NetIPInterface –InterfaceAlias <InterfaceAlias as String>                              or Get-NetIPInterface –InterfaceIndex <InterfaceIndex as UInt32>


Another command that you can use for this purpose is the following one
Get-NetIPConfiguration
Issuing this will command will give you the details of the IP Network Interfaces as shown below


If you want to get the details of a particular interface use the following command
Get-NetIPConfiguration –InterfaceAlias <InterfaceAlias as String>
                       or
Get-NetIPConfiguration –InterfaceIndex <InterfaceIndex as UInt32>
[Note: You can use any of these commands to find the InterfaceAlias or InterfaceIndex for the commands below and for commands in Part 2 of this post]
To view the status and properties of the network adapter
Get-NetAdapter
This will list the Name, InterfaceDescriptuion, InterfaceIndex, Status, MAC Address and Speed of all the visible network adapters in the system.
If you want to view the status of the hidden adapters also, use the following command
Get-NetAdapter –IncludeHidden
To disable a network adapter First find the InterfaceAlias using the “Get-NetIPInterface” command or InterfaceDescription using “Get-NetAdapter” of the desired interface. Now use the following command
Disable-NetAdapter -Name <InterfaceAlias>
                                              or
Disable-NetAdapter -InterfaceDescription < InterfaceDescription>
To disable a network adapter without asking for confirmation, use the following command
Disable-NetAdapter -Name <InterfaceAlias> -Confirm:$false
                          or
Disable-NetAdapter -InterfaceDescription < InterfaceDescription> -Confirm:$false
To enable a network adapter First find the InterfaceAlias using the “Get-NetIPInterface” command or InterfaceDescription using “Get-NetAdapter” of the desired interface. Now use the following command
Enable-NetAdapter -Name <InterfaceAlias>
                           or
Enable-NetAdapter -InterfaceDescription < InterfaceDescription>
To disable IPV6 in a network adapter First find the InterfaceAlias using the “Get-NetIPInterface” command or InterfaceDescription using “Get-NetAdapter” of the desired interface. Now use the following command
Set-NetAdapterBinding -Name <InterfaceAlias> -ComponentID ms_tcpip6 -Enabled $false
                                            or
Set-NetAdapterBinding -InterfaceDescription < InterfaceDescription> -ComponentID ms_tcpip6 -Enabled $false
Before Disabling IPv6
  After Disabling IPv6
Setting IPv4 address to a network card First find the InterfaceAlias or InterfaceIndex using the “Get-NetIPInterface” of the desired interface. Now to set the IP address, Subnet mask and default gateway for the desired network card please use any of the following command.
New-NetIPAddress –InterfaceIndex <InterfaceIndex as UInt32> –IPAddress <IPAddress as String> –PrefixLength < PrefixLength as Byte> –DefaultGateway < DefaultGateway as String>
                                                        or
New-NetIPAddress –InterfaceAlias <InterfaceAlias as String> –IPAddress <IPAddress as String> –PrefixLength < PrefixLength as Byte> –DefaultGateway < DefaultGateway as String>
