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.

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

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

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.


Wierd.
