We have recently moved DHCP Server from Cisco switch to Windows 2003 Server. DHCP server seemed to be working fine in the beginning, but every morning some users, who receives dynamic IP address, are having problem. Users with problem are running WinXP, and they can’t ping dhcp server or other servers, and can’t find printers as well. Servers are all configured with static IP, and printers are all network printers with static IP address. Approximately 10 people are having problems everyday, and I can’t figure out why they have problem every morning. There is another server that is replicating from main DHCP server, and we have secondary DNS server as well. Please HELP
