Hey folks – Hilde here with a post about some DHCP migration snafus I've bumped into recently.
Many of my large, enterprise customers have DHCP servers that were deployed over a decade ago, humming along on some flavor of the Windows Server 2003 OS (WS 2003).
For the most part, those DHCP services have been pretty much dial-tone over the years but with the end of support coming for WS 2003 (that date is July 14, 2015, by the way), they are migrating the service to a newer OS version.
You know what they say about sleeping dogs? Well, there's nothing like walking by the sleeping DHCP dog and stomping on his tail.
TOPIC #1 – existing DHCP-registered DNS records get deleted when you disable/delete the scope on the old DHCP server.
TOPIC #2 – DHCP authorization details in AD are showing up inconsistently and/or in different locations. You're wondering what's going on and how/why they got there.

So, what's the bottom line here?
