Client site had a power outage while system was up in KUbuntu. After all came back up I am unable to ping or print to a network printer which was previously working on this machine.

All other users going through the same router/hub to the same printer have zero issue.

I can reboot this machine in XP and it prints just fine as well.

12.04 LTS cannot be moved to anything else due to project we are on.

This is most odd.
