i'm going with dhcp, arp, dns, http
dhcp to get its own ip address, etc
arp to to test for duplicate host address
dns to resolve .com address
http to receive info

and a host doesn't do osfp and it doesn't need to do a icmp. So, it is these 4. hopefully, I have the order right.

DHCP, ARP, DNS, HTTP like clarson said should be the right answer.

DHCP to get an address. ARP to resolve the default gateway MAC. DNS to resolve the hostname. HTTP to access the site.

OSPF is not something the PC participates in. ICMP shouldn't be neccessary for the steps described.

heero, wouldnt the host need to use dns to resolve the hostname's ip address before using arp to resolve the default gateway's MAC. The host would need to know that the .com ip's address isn't on it's local network. and, therefore would need to send it to the default gateway. and, then use arp to find the gateway's mac because it isn't in the host's mac table yet.

I think this is where things like wireshark come in handy for learning tools. You can see wireshark to capture traffic and watch how it works from start to finish.
