Why am I unable to reach local network computers, but able to browse the web?

Why am I unable to reach local network computers, but able to browse the web?

I have a weird problem. Today after turning my Ubuntu 9.10 PC on I can't connect to my local network, but I can use the Internet. We have a single Windows 2003 server machine that acts as a local main DNS server, DHCP server and a domain controller. Although it seems to give me the local IP address, I can not ping it, as well as any other machine on the net.

"I'm not sure, but I don't like your metrics.
This excerpt from the Unix man page of route is suggestive:

A metric of 0 implies that the route
does not refer to a gateway, but
rather to one of the machine's
interfaces. Destinations matching such
a route are sent out on the
interface identified by the gateway
address. For interfaces using the ARP
protocol, a metric of 0 is used to
specify all destinations are local,
meaning that a host should ARP for all
addresses by adding a default route
containing a metric of 0, as
illustrated in the following example:

route add default 0

<hostname> is the name or IP address
associated with the network
interface all packets should be sent
over. On a host with a single network
interface, is normally the
same as the returned by
uname -n.

Did you change the original metrics? Maybe you should set them all to 1.
In any case, I suggest that you compare these values with another machine on which the network works."
