Two tcp domain - one ip address

Dear Sir,
How can I have two tcp/ip domain name points to one IP
address? How to do it in Windows DSN server and exchange
server? Where to go to look for more info?
Detail:
I registered two tcp/ip domain
name "mycompany.com", "myc.com" from networksolutions.com
Setup my Windows 2003 Server to domain mycompany.com
Setup another machine to be exchange server 2003
Now, I have my A record setup, and MX record setup
already. Both A record has the same IP address. The MX
records of mycompany.com and myc.com is handled by
mycompany.com server.
I cannot get the mail server machine to handle the mail to
(E-Mail Removed). I cannot set the DSN server at the
mycompany.com machine to add myc.com domain.
Am I doing correctly?
Where to go to look for more info?
Thanks for your help in advanced.

You should be able to add to create a Standard Primary Zone for myc.com.
What error or message are you getting when you try to do this?
