If you have Norton Antivirus, there are some files that interfere with Zone Alarm unless specifically granted access to the internet by Zone Alarm. Look on Symantic Support and find "Document ID:2003082012355706 Last Modified:05/19/2004". I followed the instructions to permit Zone Alarm to allow access by all the Antivirus progrm files and it seemed to workfor my Outlook Express problems, it may work for IE6 problems.
