IIS6 has been rock solid.
As paranoid as I am I have port 443 open. I never ever had it open on SBS 2000.
If you have local admin on the desktop, your risks are probably bigger over there.

There is now a need for going to work with Outlook Web Access on our company. What I first like to know is what port(s) does OWA needs to access from outside?
If I want to give our employees a save way to use this, what are the safety issues, e.g. do we need SSL etc. ?
We have a SBS2003 Premium Server with two NIC's. One for the internal network, on the other NIC the e-mail from outside is delivered. This NIC is connected to a external router and firewall and for this NIC only port 25 is open. We do not use ISA.
Is it save to open the required ports on the firewall, to give employees access?
Thanks in advance,
Gerko
