What cable needs to be run for Ethernet?
it will be better with CAT 6..it performs better than CAT5 (this is my opinion) ——– To be certified for GigE (1000 Mbit) connections you need to use CAT6. However CAT6 is much more expensive.

How can we make a site respond to www. and just http?
You should have an A record for www.yourcompany.com in the DNS zone. Setup a CNAME for yourcompany.com pointing to www.yourcompany.com. This will get the DNS working. You may need to configure IIS to accept both names if you are using hostnames. If you aren’t using hostnames there’s nothing else to configure.
