ping gateway ok, ping any other local network address fails
Hi,
First, I tried to understand why a single machine among others couldn't
print on the local printer.
So I tried to ping the printer and it failed.
The machine could nevertheless surf the web with no problem ...
I paste here a few commands I passed when remotely connected to the
problematic machine (sorry for the french locale).
What should I check next ? Ideas ?
Thanks
