DHCP with unknown Unique ID

Hi,

Do anyone know what device will have such long mac address
(3139322e3136382e36382e31383300) in the unique ID field?

We setting up a DHCP server for not more than 10 PCs, but many of such kind
of device occupied the IP Address, it always make no IP address for users' PC.

In the DHCP Console, we always found those entry even after we delete them.
192.168.68.183 192.168.68.183 7/24/2007 2:30:18PM DHCP/BOOTP
3139322e3136382e36382e31383300

Is it Windows 2000?

Regards,
Carina Szatori

Jonathan,

As I am sure you know, this is not a valid ID and DHCP would not be able to
send to it on layer 2. You might try pinging the device to see if it
responds and even ping -a to see if you can do a reverse DNS lookup. This
will help you track it down and triage.

From here, I would pull the record and get that host to pull another DHCP
address.

Hope this helps.
