Convert a Dynamic IP to Static

October 18, 2018 by mo wasay

Working on a project where on some servers the DHCP assigned addresses needs to be converted to static. Since there is always more than one…I needed to script it. Here is a quick way to do it via PowerShell.

#SwitchIPtoStatic.ps1
#Get All the adapters that are on the Server
$adapters = gwmi -cl win32_networkadapterconfiguration | ? {($_.ipaddress) -and $_.dhcpEnabled -eq 'True' }

foreach ($adapter in $adapters) {
    # Get original settings
    $ipAddress = $adapter.IPAddress
    $subnetMask = $adapter.IPSubnet
    $dnsServers = $adapter.DNSServerSearchOrder
    $defaultGateway = $adapter.DefaultIPGateway

    # Set to static and set dns and gateway:
    $adapter.EnableStatic($ipAddress,$subnetMask)
    $adapter.SetDNSServerSearchOrder($dnsServers)
    $adapter.SetGateways($defaultGateway)
}

#SwitchIPtoStatic.ps1

#Get All the adapters that are on the Server

$adapters = gwmi -cl win32_networkadapterconfiguration | ? {($_.ipaddress) -and $_.dhcpEnabled -eq 'True' }

foreach ($adapter in $adapters) {

# Get original settings

$ipAddress = $adapter.IPAddress

$subnetMask = $adapter.IPSubnet

$dnsServers = $adapter.DNSServerSearchOrder

$defaultGateway = $adapter.DefaultIPGateway

# Set to static and set dns and gateway:

$adapter.EnableStatic($ipAddress,$subnetMask)

$adapter.SetDNSServerSearchOrder($dnsServers)

$adapter.SetGateways($defaultGateway)

}

Hope this helps!
