I seem to have a very strange problem with DHCP Server.
DHCP Server on VLAN interface having 1 pool of 99 IP addresses.
It was working fine until all of a sudden PC's were not accepting any IPs assigned to them with errors:
dhcp(LAN) client XX:XX:XX:XX:XX:XX declines IP address 172.16.10.x
I know that probably a power cycle reset will fix the problem, however this is a live system and connot reboot it easily.
