Thanks for reply but I have few basic doubts,
when only a small amount of the lease time has passed ---->
when can we see this type of situation ?
FYI: The lease time for the scopes is one hour in my config,
Do I need to add any config statement in dhcpd.conf or increase lease-time
to stabilize the environment
Thanks in advance
