Multiple DHCP requests during boot?


A

Andy

My network consists of a number of devices, including
several XP worstations, connected to an ADSL router
(Alcatel SpeedTouch 510). The router is providing DHCP &
DNS services and everything works nicely EXCEPT that I
have a strange problem on one of the XP boxes.

What happens is this:
- After booting up this machine it always thinks it's ip
address is 10.0.0.4
- Everything else (including DNS) thinks the address is,
say, 10.0.0.19 (or whatever DHCP gave it)
- When I look at the DHCP leases on the router it looks
like this machine is doing 3 dhcp queries every time it
boots. All are successful. I can see leases for:
10.0.0.4
10.0.0.18
10.0.0.19
all assigned to this machine in this order. So the
workstation seems to stick with the first address it got,
and DNS ends up with the last. Hence they never match.

Any idea why this machine is doing 3 dhcp queries? The
second two happen several seconds after the first.

From the DHCP leases I can see that the MAC address for
the first request is correct address and the second &
third addresses have a version of the same MAC address
padded with some extra bytes.

Any ideas?

Any assistance gratefully received - this is driving me
nuts!

Andy

Check to see if you have a 1394 and or a bridge in network
connections if you do delete them just use your local area
connection.
