What is lost on a reboot (or restart of the DHCP service) is the 10.0.0.0 network's DNS (006) option. It becomes unchecked, and I have to re-check it and enter the DNS servers again.

These were clean installs of servers, but the DHCP database has been exported/imported between the iterations of the DHCP servers. --Matt Ross Ephrata School District ----- Original Message ----- From: Andrew S.
