XP-pro SP2, DHCP doen't work anymore

[Marcel]

Hi,

I have a strange problem. I use the DHCP function from my router to obtain
an IP address. This stops working and the following IP address is put in
place: 169.254.72.200. I can't change this, refresh doesn't help. The only
thing that helps is to give my computer a manual IP address.

My questions are:
1 How is this possible?
2 Where does this IP come from?
3 Is the NIC broken. I once had a similar problem but in that case it got
169.254.0.0 a "Microsoft" IP.

I think this is not related to SP2 because I had this problem with SP1
already and started yesterday. This morning I updated to SP2 and the problem
stayed. I had no problem with SP2 it looks like everything is running
normal. I sanned my pc for virusses, I ran HijackThis but it showed the
same lines as is did before I got this problem. I ran Ad-Aware and showed no
problems.

Regards,

Marcel

If you have just installed SP2, there is a built in firewall in it.
See if it is causing problems.

2 Where does this IP come from?

This is the default IP address assigned by windows, when the IP cannot be
assigned by the DHCP.

3 Is the NIC broken. I once had a similar problem but in that case it
got 169.254.0.0 a "Microsoft" IP.

There is no such *Microsoft IP*. Yes but you can get anything in
168.254.x.x

I think this is not related to SP2 because I had this problem with SP1
already and started yesterday. This morning I updated to SP2 and the
problem stayed. I had no problem with SP2 it looks like everything is
running normal. I sanned my pc for virusses, I ran HijackThis but it
showed the same lines as is did before I got this problem. I ran
Ad-Aware and showed no problems.

Have you tried *ipconfig /renew* and *ipconfig /release*

Nup It happens on W2K too. You'll see if you ipconfig that it reads
AutoIPAddress configuration (or something similar) in the results. What
I did to get the machines talking again was to just force an IP address
on the problem box. For safety I then reserved that IP for that machines
MAC address on the router. Works good but I still have a problem seeing
the net even though I can see everything else on the network.
