AH. It's the SolarWinds IPAM (IP Address Management) module. It hooks into the DNS and DHCP servers, so you can view and manage your address spaces and name entries. And no one had added the other (new) DNS servers to the module.

That's why only some of the zones had been changed) On Thu, Jun 11, 2015 at 8:49 AM, Michael Leone <[email protected]> wrote: > This is odd. I have 8 DCs in my domain.
