I think this may well be related to MS Server 2003 but I'm not wholly certain.
Please try to give as much info about these entries and your setup as possible.

MAC info won't travel across the i'net,. but I could be wrong

do you have any kind of wireless network hooked up?

Smoothdude.

If you want to post code without the smilies showing, just below the reply window, there is an Additional Options area.

Put a tick in the Disable smilies in text, box, to eliminate them before posting back.

apparently it's related to win2003 doing some strange dhcp stuff - perhaps http://www.wilderssecurity.com/archi.../t-105112.html

or

I had the same 'detective' DHCP client show up as well, immediately after installing MS 2003 Small Business Server on my home network. I found it listed with the DHCP clients in my IPCop DHCP log and Google led me here. For the record I had 3 MACs for detective, the E9-EB-B3-A6-DB-3C one and also 4d:c8:43:bb:8b:a6 and 32:f6:9e:7d:49:dc. Interesting indeed..

Well spotted silv,

the one thing I didnt think to Google for (while trying to look clever) was the mac address, having assumed it was specific to hardware.
Other mention here
http://www.derkeiler.com/Newsgroups/...4-11/0284.html

I would not be suprised it MS broadcast that mac address to see what machines complain so they can have a server count/browser election at boot.

I'm pretty sure the mac address / dhcp protocol won't get onto the i'net so it's either from an internal box or there's something playing with the wireless - but in this case looks win2k3 specific

Yeah, I can confirm this is Windows Server 2003 - after installing it, I had these MAC addresses, too.

My server runs server 2003 business, I hadnt the detective client in my DHCP table..but after opening a RDP session I got the client too.

I guess it has to do somethin with that

I found the same thing on my DHCP table. While researching, I noticed everyone had one thing in common, a Server 2003 machine. So I queried Microsoft's website and found this. There is no trojain, no one is attacking your system.
