I have 2 servers (Windows 2000 and Windows 2003) a modem and a linksys router. For the last 2 weeks the DHCP has been dropping every 12 or 24 hours. I went into the router which is the DHCP server and set the lease time to '365'. Well the 2000 server dropped about 7:00 pm last night. With error message: DHCP Lease for this IP address has been denied. The server sent a DHCPNACK MESSAGE. So everymorning I have to reset the router because noone can access the server or the internet.
What is the cause of the drop every day/night @ the same time?
