How do I enable dynamic ip address release?

Hi,

I currently have a dhcp server which requires each computer in the
network to have its IP address reserved, instead of dynamically
assigning IP addresses.
I'm not so sure on how to turn this off though, so that whenever
anyone plugs into my network they automatically get an IP address,
instead of me needing to reserve it by its mac address.


Thanks!

Ivan,
I assume you are talking about a Windows server with a DHCP service?
If all the available addresses have been reserved you will need to
un-reserve them or add more addresses.
If you open the DHCP console and go to your scope, how big is the address
pool and how many reservations do you have?

Simple. Get rid of all the reservations in your DHCP scope.

Hi,

If I un-reserve the addresses (ie, delete the reservation from DHCP),
dhcp won't allocate IP addresses by default.
This is what I'm trying to achieve.
The only way for computers plugged into the network to get an IP
address is by reserving them.

Hello Ivan,

Why not deleting all reservations and use DHCP for dynamic assigning?

Hello Ivan,

Is the server domain controller or member of a domain?

Is the server authorized in the domain?

Is the server from MS or another vendor?

Are the clients behind a rotuer?

Hi,

Thanks for your suggestion.
I suppose my next question would be ..... How do I use dhcp for
dynamic assigning?

Hi,
The server is the domain controller.
It is authorized and is a Microsoft 2003 sbs.
The clients aren't behind a router -- they're all within the network.

I think my question is more toward the lines of what Meinoff
suggested: How do I enable dhcp dynamic allocation?

Well...that's what DHCP *does*. If you have reservations configured for MAC
addresses, someone created them - they would never have been there
otherwise. The DHCP server when configured would just hand out an address to
anyone/anything who requested one. That's the default. If you delete all the
reservations & check the scope (it should be for something like 192.168.1.1
through .254, with exclusions set for anything used as a static - I normally
exclude .1 - .100 and .200 -.254 on small networks), you'll be good to go.

Since you're using SBS, you should probably post in
microsoft.public.windows.server.sbs. However, as Bill mentioned, it sounds
like this really isn't your area of expertise and you might want to ask
someone else to help you out with it & show you in person.

Hello Ivan,

What do you mean with enable dynamic allocation? If the client machines use
DHCP and no fixed addresses and the server is authorized and the scope is
activated the clients will start a broadcast for the ip address.
