I would recommend to give it a try with another Computer/Notebook or Instant Linux CD. If you still get the phenomenon it might be your providers nameservers.
Did you check what your default nameserver thinks the IP of
www.projecteq.net is?
If you dont have any problems under Linux or with another Computer you should look into the 'hosts' file see if you find any static entries. If there are none set one for
www.projecteq.net to the right IP(66.28.184.13) and see what happens.
