If you have a firewall device often it can log internet access by IP or
possibly website name also showing the source IP address from your network.
If you are in an Active Directory domain you can also look at the cached
lookup zone of the AD dns servers that are forwarding to the internet for
internet name resolution. You have to select view of the dns Management
Console to see advanced features and then the dns cached "zone" will show
up. For a standalone computer a personal firewall such as Sygate has
extensive logging that can show details of internet use as can programs such
as Net Nanny, Cyber Patrol, etc. Port Reporter service from Microsoft is
another utility that can record all network access. --- Steve
