#1: Trend Micro PC-cillin includes a firewall capability. Using more
than one firewall can cause problems, so you must disable either
Windows Firewall or PC-cillin. I'm sorry, but I don't know how to
configure PC-cillin, and I don't know whether it's compatible with ICS
on the host computer.

#2: To find the DNS server for the host computer's public (Internet)
connection, right-click the public connection and click Status |
Support | Details.
