I setup a DHCP server at my work a couple of years ago and it is working jsut fine. I needed to setup some DHCP - Relay rules on our main Router, to enable DHCP to connect to a specific VLan, that I setup as well.
My question is regarding the setup of a 2nd DHCP router, for redundancy. Currenlty I get very nervous if I restart the existing DHCP server becasue it is the only DHCP server at my work.
My questions are,
1. Is it a good idea to have a 2nd DHCP server, for backup or reducndancy purposes?
2. Should I have them duplexed, or can I have 2 DHCP server running simultaneously?
3. What else would be required in setting up a 2nd DHCP server?
a. Is there anything I need to be careful of in setting up a 2nd active DHCP Server, will the 2 DHCP server have any problems sendign out IP addresses and working working together with the same rules(reserved IP's)?
Currently the 1 DHCP server is runnig on Wondows 2003 Server Std edition.
