Guest Marco Posted August 8, 2007 Posted August 8, 2007 Hello. In my network I have those servers: - DHCP server running on Windows 2000 server - DNS server running on Windows 2003 server How do I configure a windows 2003 Std to be a DHCP and DNS Backup. My idea is if any of the main servers failed, this server would assume those functions. Is it possible?

Re DHCP - set up another DHCP server using a non-overlapping scope.
Guest Ryan Hanisco Posted August 9, 2007 Posted August 9, 2007 Re: How to configure a DHCP and DNS Backup server This is a duplicate post in the Active Directory group. I agree with Lanwench, but I'll generall create overlapping scopes with reciprocol exclusions to avoid NAK problems. This is where a host contacts the "other" server when asking to renew the address. Since the address isn't in a valid pool it gets a NAK from the server and can stop the process there rather than requesting a new address. This means that the workstation will drop off the network when the lease expires. When they both have the same rule, the NAK doesn't occur, but the server offers an alternate address in the response. -- Ryan Hanisco MCSE, MCTS: SQL 2005, Project+ Chicago, IL Remember: Marking helpful answers helps everyone find the info they need quickly.
