Ok, I am a semi-noob at this, but I can get around most things. First of all, I set my own server up by myself, and hosted it myself. I got free DNS hosting from zoneedit.com and my domain name from godaddy.com. I was wondering, what do I have to do to get a subdomain? I was thinking it over and figured out that it must have to be done on the server side, since it would run to the domain first, then the subdomain. I am running Windows Server 2003 with IIS 6 if that helps.
I guess my question is, where do I go out of those three to set up a subdomain, will it cost extra, and what else will I need to do it?
