Guest Lori Posted June 3, 2008 Posted June 3, 2008 Running Windows 2003 Small Business SP2 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?!?!!? -- Life moves pretty fast. If you don't stop and look around once in a while, you could miss it.
Guest Cleve S. Posted June 3, 2008 Posted June 3, 2008 Re: DHCP Lease for <blank> System Name 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.
