Examples

The Enable DHCP and Assign DNS Servers VBScript code sample on TechNet Gallery uses EnableDHCP to enable DHCP and assign DNS servers to a computer.

The following VBScript code sample demonstrates how to enable 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.

Note  Supported on NT platforms only.

Set Adapter = GetObject("winmgmts:Win32_NetworkAdapterConfiguration=0")

RetVal = Adapter.EnableDHCP()

if RetVal = 0 then 
 WScript.Echo "DHCP Enabled"
else 
 WScript.Echo "DHCP enable failed"
end if

The following Perl code sample demonstrates how to enable 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.

Note  Supported on NT platforms only.


use strict;
use Win32::OLE;

my ( $Adapter, $RetVal );

eval { $Adapter = Win32::OLE->GetObject("winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2")->
       Get("Win32_NetworkAdapterConfiguration=0"); };
unless ($@)
{
 print "\n";
 $RetVal = $Adapter->EnableDHCP();
 if ( $RetVal == 0)
 {
  print "DHCP Enabled\n";
 }
 else
 {
  print "DHCP enable failed\n";
 }
}
else
{
 print STDERR Win32::OLE->LastError, "\n";
}
