View Network Client Info.

I want to see IP addresses and client names for the clients on my network (PCs and thin clients). I’ve found programs that let me see IPs and computer names on PCs, but not the names of thin client devices. What I’m basically looking for is the information that I can see in MS’s DHCP Manager (plus the few devices we have with static addresses), but in a file format in which I can manipulate the information (e.g., spreadsheet or standard database format). Is there something that will allow meto do this, either gather the information itself or let me export the DHCP database to a program that allows me to manipulate the data?
