redirect access to a subdomain on internet to a local ip using windows 2000 dns

[Sibi]

I have a windows 2000 domain with Microsoft DNS running. I use a single
label domain name (ie one without a "dot"). All memebers of my domain
accessing a particular subdomain in the internet say
www.subdomain.google.com should be directed to a local ip. At the same
time access to www.google.com should be to the original google server
in the internet. is it possible?

Would there be any benifit if i chnage to BIND as my DNS?
thanks in advance
