Don't you hate when you get support like that?!
Anywho, you forward the DNS of your sub domain at GoDaddy.
To Edit a Subdomain
- Log in to your Account Manager.
- Next to Domains, click Launch.
- From the Tools menu, select DNS Manager. The DNS Dashboard displays.
- For the domain name with the subdomain you want to edit, click Edit Zone. The Zone File Editor displays.
- In the A (Host) section, click the subdomain you want to edit.
- Edit any of the following fields:
- Host — Enter the subdomain you want to use. Type @ to map the record directly to your domain name, including thewww.
- Points to — Enter the IP address you want the subdomain to point to.
- TTL — Select how long the server should cache the information.
- Click Save Zone File, and then click OK.
Hope that helps!
