Static IP fails to DHCP

We're trying to configure a static address on an XP
machine. When the machine is restarted it switches itself
back to DHCP settings. If we switch it back to static,
same thing, next time machines restarted we lose the
static address and reverts to dhcp. It's extremely
frustrating and I can't find any help on this.

Hi
The static IP has to be out of the DHCP range.
Example, if the DHCP range is 192.168.1.1 to 192.168.1.100 static IPS have
to be above 192.168.1.100.
If the FDGCP covers the whole subnet (xxx.xxxx.xxxx.0 to xxx.xxx.xxx.255 it
has to be configured to a smaller range.

The static range is xxx.xxx.xxx.1 - 99 and DHCP is 100-49. Any other
suggestions?

A workaround rather than a solution.

Perhaps your dhcp server can reserve an ip address for the mac of the
xp box behaving in this manner.

I've had this problem before, a couple of times. The way I got it fixed was
to uninstall the NIC, then go through the registry
(HKLM\System\CurrentControlSet\Control\Network\... ..

....in there, find & remove everything that refers to that NIC. Reboot the PC
and let it redetect the NIC. See if this works.

(I do agree that if this is a networked PC, a DHCP reservation is superior
to a static....but you'd still need to fix this problem)

Thanks to all! I had tried Lanwench's suggestion, but didn't include the
registry cleaning part. I'll attempt to do that this PM.

I have multiple backups and well resort to that if all else fails.
