Could a virus do that ?

Hello,

My IP adress is normally assigned by the DHCP of my router.

It works well on all my Laptops which are linked to the router via a
wireless device (IP address given is 192.168.0.10x). But on my Desktop (it
used to work ok yesterday) which is linked to the router via a network
cable, it gives a complete different IP adress (169.254.226.159), it does
not show any DHCP address or anything else. Of course I cannot connect to
the internet.

By the way, I use win2000 and my ip configuration in the network
configuration on my non-working desktop is the same as the working Laptop
one.

I will really appreciate any help

Marc

The 169.254\16 address range is an autoconfiguration range for when a
dhcp server cannot be found (see link below) - I'd suggest that your
computer is not actually connecting to the DHCP server, and by extension
perhaps to the network. Check your cable connections or try another
cable perhaps?

Andy,

Thank you for you answer, I have checked the connection and the cable, they
are both OK, I have also tryed to connect direct to my cable modem not via
the routeur and the same thing happens ...

Any idea,
Marc

The problem getting a 192.168 IP address would seem to be a problem
connecting to whichever of the two devices on your network is acting as your
internal DHCP server [your router?]. As you may know, your computer doesn't
immediately re-try to get an IP address until you reboot or you do Start,
Run, CMD, OK and type IPCONFIG /RENEW * You must be connected to the
network when you do either of these for this to work. Even if it doesn't
work, you should at least get a more verbose error message that might help.

Since the other computer is working fine, I wonder if maybe your Windows
2000 computer is having a problem with its network card.
