Yes unfortunately I need to forward some ports (Azureus and others) to this machine.

But I tried that anyway and I can't activate the interface when I use DHCP...
The error message: Check that the network settings are correct and the machine connected to it.
But DHCP worked on the Knoppix LiveDVD 5.1.1 which I used! (was used to install to disk)

There are about 5 windows machines on DHCP on this network so I don't think there is a problem with the DHCP settings of the router.

The same thing happens when I use the DNS servers provided by my ISP. They disappear on a reboot or arbitrarily after some hours.

I've never seen such behaviour on this network and have been using a static IP on WinXP for more than 2 years so I'm pretty certain its something in my new setup or configuration. I have kept my WinXP partition and this doesn't seem to happen. DHCP works as well there.

Any ideas?

Do you think that changing the /etc/resolv.conf file permission to non-writeable is ok to try as a workaround?


Many thanks
