Frequently when you are not able to access you site through your domain name it is because your Internet Provider has not refreshed their cached DNS's. You can force a refresh by performing a flush of the DNS through the utility command (pc) or terminal (mac).
In Windows XP:
Go to Start->All programs -> Accessories -> Command Prompt
Type in "ipconfig /flushdns" and click enter
Once this is complete try accessing your site again through the domain name
In Windows Vista:
1. Click the Microsoft Vista Start logo in the bottom left corner of the screen
2. Click All Programs
3. Click Accessories
4. RIGHT-click on Command Prompt
5. Select Run As Administrator
6. In the command window type the following and then hit enter: ipconfig /flushdns
7. You will see the following confirmation:
Windows IP Configuration Successfully flushed the DNS Resolver Cache.
To flush the DNS cache in Mac OS X 10.5 and 10.6, run this command in Terminal:
sudo dscacheutil -flushcache
To do the same in 10.7 and 10.8, run this command:
sudo killall -HUP mDNSResponder
As Apple points out, you might need to do this in the following situation:
"OS X keeps a local cache of resolved DNS queries for a time defined by the DNS server, but sometimes it may be necessary to reset the cache immediately and re-query a DNS server. For example, you might do this after an entry on the server is changed or a new entry is added."
In Mac OS X (Leopard and Tiger):
From your hard-drive/"Finder" window, open the "Applications" folder and click on "Utilities"
Double click "Terminal"
Type in "dnscacheutil -flushcache" and click enter
Try accessing your site through the domain name
