Hummm... mine shows 192.168.0.0   but netmask is the same,  but I dono 
if that makes a difference or not.

Have you ever pinged any other machines from it? (The Windows machine?)
Do you see anything in C:\hosts ?
Do you have DHCP enabled on the Windows box? Or not?  
If your using static IP on both, do you have the subnet mask right, and 
broadcast address right?
Do you have a DNS on either machine?

so you have lines like:
nameserver ###.###.##.#
nameserver ###.###.##.###
?

You might also need
search mydomain.name.thismachine
and/or
domain mydomain.name.thismachine

or
domain name.thismachine
search name.thismachine
where   name.thismachine   is last two parts of the output of:
# hostname

I dono about debain but RH and some others will also have lines like:
NETWORKING=yes
HOSTNAME=whoever.whatever.wherever


And what about the equivalent to:

/etc/sysconfig/network-scripts/ifcfg-eth0

and do you have /etc/hosts.allow and/or /etc/hosts.deny ?
