Tomek, Please remember I tried the version 4.4.2 as suggested and as you say Ubuntu used 4.4.1, so it could be something to do with the 4.4.1 release or the ubuntu changes. Either way it looks like its not going to be fixed. Given this how do you apply to have a ISC-DHCP_Server removed form the Ubuntu bundle for no maintenance.
