Sometimes the OLD DNS entry will be cached and you will need to either flush the DNS cache to get rid of it, or wait up to 24 hours for it to be dropped from the cache automatically.

To do this in windows click on Start=>Run

then type: cmd

in the black window type:

ipconfig /flushdns
Press enter.

If you get an error saying:


1. Click Start or Windows logo at 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.




If you get an error msg saying:
" Windows IP Configuration
Could not flush the DNS Resolver Cache: Function failed during execution."

Go to: Start>> Control Panel >> Administrative Tools >> Services (Open services)



in the list find: " DNS Client" right click >> Properties >> Change "Start up Type" to automatic >> Click Start

Now you should be able to flush your dns.



After done make sure you put back DNS Client to disabled.
