Trying to match fields and return a value

We have a project here that requires some matching of cells and I am not sure
the proper function to use. Here is the problem:

We are trying to match errors in firewall logs to see who is causing
problems on the network. So on Worksheet1 I have a column of names, IP
addresses, and MAC addresses. On worksheet2 I have a list of computer names,
IP addresses, viruses detected, and MAC addresses. What I want to do is
create a new worksheet (worksheet3) that will look at the first 2 sheets and
create a sheet that matches MAC addresses on sheets 1 and 2. The third sheet
should allow me to match a name to MAC address, so on worksheet 3 I would
like to have the following columns(and where data comes from):
Name(worksheet1), IP Address(worksheet2), Computer name(worksheet2), MAC
address(on both sheets, need to match), and number of viruses(worksheet2).
Any thoughts on which formula to use??

Once you get your key column into that third worksheet, it sounds like you'd
want to use =vlookup() or =index(match())

And Debra Dalgleish has some nice instructions (for both) at:

and
http://www.contextures.com/xlFunctions03.html

And if that list of MAC addresses is different on each sheet, you may want to
copy from one worksheet, then copy from the second worksheet (right below
it--creating a giant list with some duplicates).

You can get rid of those duplicates by using data|Filter|advanced filter.

Debra also has instructions for that at:
