I have configured my DHCP server in a SBS 2008 box and all of a sudden all the leases occupied by BAD ADDRESS. Clients are not even getting the IP address from server and showing IP Address conflict. if I put a static IP which is out of my DHCP scope, to any of the system it will not accept the IP showing conflict.
this became hectic now. I changed the IP address range from 192.168.1.0 to 192.168.2.0 but no luck and same problem.
other devices connected to network are Linksys Wifi AP, HP Procurve switches, Printers, Site to Site Wireless equipment.
