www prefix in subdomains

How to set it up? Does it make a difference?

We are running Windows (NT) 2000 DNS and we can easily setup a subdomain.domain.com host or alias, but how do you setup www.subdomain.domain.com? It does not allow periods in the host name. We have sucessfully done it by creating a new zone subdomain.domain.com but hosts in this zone are only resolvable locally since there is no entry in the Top Level DNS for subdomain.domain.com to tell it where to go to resolve hosts in that domain. Seems like the only way to do it is to manually edit the zone file on the DNS.

Also, it seems far more of the top listings on Altavista that have subdomains are www.subdomain.domain.com than on Google. This leads me to believe there is a chance the www may make a difference on the ranking, maybe not?

In domain.com you have to have an entry that deligates subdomain.domain.com to your name servers. That's the piece your missing. I'm just not familiar with windows DNS but in bind I'd add something like this to domain.com's zone file:

subdomain in ns 127.0.0.1 # Or whatever the DNS IP is
