When I use another ISP connection, I get "cookies" (I think) related problems when i try to post to certain forums or get e-mail . I've turned down all Security and Privacy settings in my only browser (MSIE5) and disabled my McAfee firewall to standard and lower settings and it still doesn't work. I may have blocked some ISP alert related to the ISP before but I can't figure out how to get it working again.

Thanks in advance.
