EnableStatic method of the Win32_NetworkAdapterConfiguration class

The EnableStatic WMI class method enables static TCP/IP addressing for the target network adapter. As a result, DHCP for this network adapter is disabled.

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.

uint32 EnableStatic(
  [in] string IPAddress[],
  [in] string SubnetMask[]
);

IPAddress [in]

Lists all of the static IP addresses for the current network adapter.

Example: 155.34.22.0.

SubnetMask [in]

Subnet masks that complement the values in the IPAddress parameter.

Example: 255.255.0.0.

Returns a value of 0 (zero) for a successful completion when a reboot is not required, 1 (one) for a successful completion when a reboot is required, and any other number if there is an error. For more information on error codes, see WMI Error Constants or WbemErrorEnum. For general HRESULT values, see System Error Codes.

When using EnableStatic to change the IP address of the remote computer, while being connected through that adapter, you will likely loose connection to the remote computer, and receive an RPC not available error-message. (the settings are changed however). To avoid this scenario, consider changing the Gateway and/or DNS-settings prior to setting the adapter's IP-address.

When using EnableStatic to give an adapter a static IP configuration, the function returns an "81 - Unable to configure DHCP service" if the adapter is already configured with a static address. However, the function still succeeds in setting with the new operation.

The following VBScript sample demonstrates how to disable DHCP use on an instance of Win32_NetworkAdapterConfiguration. In this case we specify the adapter with an Index of 0. The correct index should be selected from Win32_NetworkAdapter instances for other interfaces.

Set Adapter = GetObject("winmgmts:Win32_NetworkAdapterConfiguration=1")

ipaddr = Array("1.1.1.1")
subnet = Array("255.255.255.0")


RetVal = Adapter.EnableStatic(ipaddr,subnet)

if RetVal = 0 then 
 WScript.Echo "DHCP disabled, using static IP address"
else 
 WScript.Echo "DHCP disable failed"
end if

The following Perl sample demonstrates how to disable DHCP use on an instance of Win32_NetworkAdapterConfiguration. In this case we specify the adapter with an Index of 0. The correct index should be selected from Win32_NetworkAdapter instances for other interfaces.

use strict;
use Win32::OLE;

my ($Adapter, @ipaddr, @subnet, $RetVal);  
eval { $Adapter = 
 Win32::OLE->GetObject("winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2:Win32_NetworkAdapterConfiguration.Index=\"0\""); };

unless ($@) 
{
 push @ipaddr, "192.168.144.107";
 push @subnet, "255.255.255.0";

 $RetVal = $Adapter->EnableStatic(\@ipaddr, \@subnet);

 if ($RetVal == 0) 
 {
  print "\nDHCP disabled, using static IP address\n";
 }
 else 
 {
  print "\nDHCP disable failed\n";
 }
}
else
{
 print STDERR "\n", Win32::OLE->LastError, "\n";
}
