I found this info on the Subject, but it doesn't specify what the data
type of the custom option should be:

Microsoft DHCP Server does not have default support for option 82 as it
has for other standard options.
Using DHCP Server Management console (dhcpmgmt.msc) -> <DHCP Server> ->
Right Click -> Set Predefined Options..., you can add option 82 as a
customized option for DHCP Server. Thereon, on the DHCP Client you can
use DhcpRequestParams API to retrieve the options for your further use.

What I ultimately want to do is use the Win2k3 server to pull the info
from the option 82 command I've enabled on my switches.
Hardware used: Cisco 3750 switches.
thanks in advance.

I must have missed the announcement, did Microsoft buy Cisco or was it
the other way around?

It is not an option by default on a Microsoft 2k3 DHCP server but the
webblog from microsoft said you can add another Custom Predefined
option type to the DHCP service and I was asking for some more steps
about doing this on a windows 2003 server.
Or how else do I take advantage of the option 82 information that is
added to packets without buying a CNR (Cisco network registrar)?

comp.dcom.sys.CISCO .... not really the best place to ask a Microsoft config
question!

The information provided by Option 82 sounds like a good idea, but in
reality its not that helpful because the data is encoded in a fashion that
is not readily human readable. You will need to develop something to grab
the option 82 data from the server, parse it, and then display it in human
readable form. You must have DHCP snooping enabled on you switches, which
does present the same option 82 information that you can easily see. Use
"show ip dhcp snooping bindings" to see the data.

Is there a way to output the "show ip dhcp snooping binding" to a file?
tftp or log it somehow?
