Title:
  dhclient: No DHCPOFFERS received

Status in “isc-dhcp” package in Ubuntu:
  Expired

Bug description:
  I have 14 x Dell c6100 servers running ubuntu 12.04 Lts. Plus  2x
  running ubuntu 10 lts (they work fine). Have been running fine for a
  year. The systems are updated regularly. After a update + reboot they
  fail to get a IP from the DHCP server.

  In the syslog I see that the dhclient dhcpdiscover on eth0 to 255...
  then dhclient: No DHCPOFFERS received

  The onboard chip is: Intel 82576
  The DHCP server is also running Ubuntu 12.04 lts.

  Have there been any changes to the dhcp-client that might explain
  this.

  I have tried disabling ufw and apparmor, but still nowhere.
