Another Dns Question <solved>

[PCTech]

How do you make a subdomain point to another port on the same computer?* like share.domain.com = domain.com:81

so I could have a webmail server setup on port 81 and my main server on 80.* That way I could mask port 81 and not have the users type it in!* Also while i'm on subdomains, how do you make one that points to another directory like sub.domain.com would really = domain.com/directory

I'm using Microsoft DNS Service, and would prefer to use this!* Also i'm on Windows 2000 Adv. Server.* Thanks for all the input

Thanks,
