In DHCP leases I have a 'Client IP Address' that is leased to a <blank>
system 'Name'. All other systems that should be obtaining an ip via DHCP are
listed in the 'Name' column by systemname.domain.com. I've never seen a
<blank> entry before & want to figure out where it's coming from!

-- I've deleted it, but it always comes back - when I delete it, there are
no complaints of something / somewhere not working
-- No record of a matching ip in DNS - I've purged the cache
-- No record of a matching ip in WINS
-- nbtstat -A xx.xx.xx.xx comes back with 'Host not found.'
-- I've deleted it, rebooted the server & within minutes it's back again
-- All the clients (point-of-sale units), network printers & the one server
have static IPs except for the few PCs which are correctly listed in DHCP's
Address Leases
-- Whatever IP it gets assigned it's always pingable

Short of doing a ping -t and going from jack to jack unplugging one thing at
a time & seeing when the ping drops how can I figure out what device this
is?!?!!?

Lori,

I have some active leases that have no entry in the Name column. In my case
I know that they are from thin clients that are not members of the domain.
