The network administrator will have the policy for assigning IP numbers. If its dhcp, your box will be given one. Other wise, you will be assigned one. In neither case can you just pull an IP out of the air. Even if you don't currently conflict, you may at some point. All you need is an IP number, what OS you use is beside the point. If the problem is "malfunctioning of [your] DNS server" and you get a warning when you boot windows, then the problem isn't linux-based and you can just report the windows error message. One off-the-wall clue. Recently it was mentioned on a thread that the MAC address is now mutable by drivers. If the windows box is set to set the MAC address to something specific while Linux just uses the built-in MAC address, they will get different IP numbers from a dhcp server. This may or may not be an issue in your case. You have a political problem best served with a political solution. If you don't own the network to which you are connecting, you have to work with the people who do. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
