Comment 4 for bug 203849

I'm a newbie and did a clean install on HH 8.04 server, with desktop loaded on top (for gui interface) and I'm trying to see a windows computer, unsuccessfully so far. Can I ignore this error? This is what I get back

kenneth@ubuntu:~$ sudo /etc/init.d/networking restart
 * Reconfiguring network interfaces... RTNETLINK answers: No such process
postconf: fatal: open /etc/postfix/main.cf: No such file or directory
SIOCDELRT: No such process
postconf: fatal: open /etc/postfix/main.cf: No such file or directory

any help is greatly appreciated
