Hi Bill ! yes, DHCP can be reliable without dual server but you need to understand that you are putting all the eggs in the single bucket and for some reason if that bucket breaks you will loose everything.
The idea behind DHCP failover is to configure two DHCP servers to operate as a redundant pair. If one server is down, the other server seamlessly takes over so that new DHCP clients can get addresses and existing ones can renew them. Clients requesting new leases need not know or care which server is responding to their request for a lease. These clients can obtain leases even if the main server is not operational.
This redundant setup not only gives you peace of mind but also give you opportunity to bring down one server, in case you want to do some schedule maintenance without effecting anyone.
No it isn't CNR is compatible in a Windows 2000 environment.
I would howver like to know if you can import current Microsoft DNS entries into CNR. I am about to install CNR to replace our ageing NT 4.0 DNS/DHCP Server. Is there any documentation or guidance for this procedure?
We are looking at replacing our Hubs and switches to a fully switched enviroment. We have 6 floors in the building. Would like each floor to have Switch with 10/100 and a uplink of 1000mbs. If we use the 2950's for this, can i use a 3750 as the core switch and have the 1000 uplink connect to the ports on the 3750 which would be 10/100/1000 ??? Would like to use the 4500 or 6000 switches but cost may be an issue for next year.
Hi Mike ! Depending on how your Network is setup, you can use 3750 as a core switch but you have to keep in mind that, you will not get better performance out of it like you'll get by using 4500 or 6000, I understand that you have cost as constraint there, but if you are putting your Network,chances are that you would like something that would go long way as far as performance and goals are concerned and with 3750 you'll not get "core' performance, as it was desiged for Access/Aggregation in mind.
Having said that, depending on number of PCs connected to your switches on your network you may or may not see the "Significant" difference.
I would strongly encourage you to go through following url and see the datasheets and other details before making final decision :
