Joost was probably not suggesting the use of static IPs here, he was |
| 10 |
suggesting to fix a certain MAC to a certain IP employing dhcp (or I |
| 11 |
didn't understand properly what you both are talking about here ;-). |

Did you make sure that the two IPs are issued to the same MAC? I don't |
| 20 |
have much experience with the ISC server, but I'd think this should not |
| 21 |
happen. |

Just a wild guess: does the client update its time (by running |
| 23 |
ntpclient or similar) during boot so it might think different about the |
| 24 |
age of its dhcp lease than the server? |
