I had similar problem with new weblogic 8.1 installation on new Windows 2003 box. Unfortunately my network card was not supported by the new windows and hence i could never connect to internet. If you are connected to internet once, your computer hostname to internet address mapping is saved somewhere in the cache and weblogic server does not throw the host exception. I resolved this issue by adding the following line in the hosts file. <computer name> 127.0.0.1. Hope it will help you resolve the issue.
