A have some questions:

1- I´ve installed NTLM to use my web browser(Opera 7.11) with ISA Server but I have to authenticate in a specific port (5865) and can´t log on my intranet that is outside of it.(Can´t acess the proxy server) Is there a solution to view my Intranet?

2 - I am using Opera that show up the best stable option considering that you can choose what web browser you can simulate(IE 6.0).Some pages do not load and others does.
Any solutions?

P.S - I am using a slow machine with Red Hat 7.1 adn Blackbox Windows manager

Thanks everybody
