Problem: my win2000 box comes up on the wireless network. It shows up in the DHCP list as having two mac addresses and three (internal) IP addresses.
The computer in question is set to retrieve its IP via DHCP automatically. Basically, the behavior looks to the naked eye like this:
* Machine comes up, gets DHCP address (let’s say 192.168.0.49) assigned to MAC address 1. This is the MAC address reported by ipconfig /all.
* A couple of seconds pass and at the end of the boot sequence suddenly two more entries show up in the DHCP list (let’s say 192.168.0.2 and 192.168.0.3), *both assigned to a MAC address I’ve never seen before*.
* The computer in question is a Dell inspiron 4000 from around 2000. It has a Linksys wireless card in it that has been functioning fine for several years without demonstrating this behavior. What I mean by this is that as far as the computer is concerned there is one NIC with one MAC address on board (certainly not two).
I will happily divulge more details if anyone is interested and can point me to what’s going on.
First off, is there any way for me to figure out what the hell this MAC address is? It’s not to my wireless card, that’s for sure.
Second, why on earth is my DHCP server (a Nexland router/firewall) happily assigning two IP addresses to the same MAC address?
Thanks,
Laird
