resolving ip addresses to host names.

While monitoring our badndwidth usage through our firewall, we sometimes find an IP address using a huge chunk of bandwidth.  We would like to find out who it is, but we use DHCP, and when I "ping -a <ip address>" the address I get back the host name of a computer shut off or nothing at all.

Is there any sure fire way to resolve an IP address to a hostname?  What if the computer isn't part of our domain, but is recieving ip addresses from our DHCP server (Windows 2003 server)?

You should be able to view all of the IP assignments in your DHCP app.  It should tell you the client IP address, host name, and so on.
