That is a little misleading... There is nothing stopping you from setting up two servers with the same scope. They will each have a fair amount of "BAD_ADDRESS" records in their lease table, but it won't harm anything per say. So, to clarify, there are better ways to do it than have the same scope on two different machines, but it is possible to set it up that way. And I agree with the "cluster" comment. If you've got a whole bunch of disposable income, send it to me... don't waste your money on the cluster setup just for DHCP...

You can not have Server 1: 192.168.0.1-255 Server 2: 192.168.0.1-255 But you can have: Server 1: 192.168.0.1-130 Server 2: 192.168.0.131-255 (This would not work if you use most of your subnets adresses. But if you have a high lease time, you have good time before clients starts renewing while one server is down.) A DHCP client renews his lease after 50% of the total lease time. If the server that gave him the adress is not avaliable, it tries again, until something like 80% (Not sure about the exact number) before it tries a broadcast, and gets an adress from the second (or third) server. This way one server would host adresses if the other goes down. DHCP is a "Cluster enabled feature". But this requires 2 * Windows 2000 Advanced Server, and some quite expensive hardware. I would not think you should buy a cluster just for DHCP, but you might use the cluster for this if you have it for other features, like file sharing or Exchange. http://support.microsoft.com/default.aspx?scid=kb;EN-US;226796 Mvh Svein Arild -----Opprinnelig melding----- Fra: Rod Falanga [mailto:rfalanga@xxxxxxx] Sendt: 10. februar 2004 17:59 Til: nmcs@xxxxxxxxxxxxxxx Kopi: windows2000@xxxxxxxxxxxxx Emne: [windows2000] DHCP servers in a Windows 2000 AD network I administer a Windows 2000 Active Directory network. However, I don't have a lot of training at this sort of thing, but I do have some. Anyway, I've got a question about DHCP servers in a Windows 2000 AD network. What I would like to know is, if there is 2 or more servers that act as DHCP servers, do they replicate information between the 2 of them? Or put differently, if I want to make one of my servers which isn't a DHCP server, into a DHCP server, do I have to do some sort of "copying" of information from the previous DHCP server to the new DHCP server?
