OK, you should be able to change the registry and then tell NDIS to rebind
the adapter (which causes the old IP address(es) to be disconnected, and any
current registry settings to be used). Here's the C code to do the rebind
(you can find this easily in the newsgroup archives):
-----
// Open the NDIS driver.
HANDLE hNdis = CreateFile( _T( "NDS0:" ),
GENERIC_READ | GENERIC_WRITE, 0, NULL,
OPEN_EXISTING, 0, NULL );
// Send the device command.
TCHAR errs[ 512 ];
DWORD xcount;
if ( DeviceIoControl( hNdis, IOCTL_NDIS_REBIND_ADAPTER,
buf, _tcslen( buf ) + sizeof( TCHAR ), // buf contains the name of the
adapter
NULL, 0, &xcount, NULL ) )
{
OutputDebugString( _T( "Adapter rebound\r\n" ) );
}
else
{
_stprintf( errs, _T( "DeviceIoControl failed. error = %d\r\n" ),
GetLastError() );
OutputDebugString( errs );
}
CloseHandle( hNdis );
