[plug] Ubuntu 6.06 installation/address resolution - update.

[William Kenworthy]

I doubt that its NetworkManager.  More likely you are using dhcp on your
ubuntu machine and obtaining the network info from your gateway.  There
are arguments to most dhcp clients (I use dhcpcd which needs "-NR") that
stops it overwriting resolv.conf, hostnames, ntp.conf and so on.  Also,
are you sure that your gateway is correctly configured?

Similarly, for the original query, its likely that that the gateway
might be at least part of the problem - have you checked the gateway
settings?  Just because windows works doesnt mean that its correct - MS
have a lot of workarounds in apps like IE and windows itself so
improperly configured equipment might still be able to get a network
connection, where linux is more likely to balk and tell you to fix it
before it will go on.
