Question : Change WINS & DNS IP addresses

I need a script to change the current WINS & DNS IP addresses with some restrictions.  
If a particular IP address exists then do not change it otherwise change to new address.
Also, the primary and secondary have to be specified in certain order per request.  
I've scripted NETSH but can't get it to do all the above?  Please help thank you
