DHCP Server Scope running out if IP addresses
Hello Everyone,
I am running out if ip address on my dhcp server. I am trying to determine the best way to resolve this issue. Should I create another scope with a different set of ip addresses or should I delete this scope and recreate it with the new range of ip addresses. Can anyone help?
Thanks,
Bill

I would recreate it with one IP range just for ease of management, but technically another scope would work as well.
Its up to you, either is a solution. I would tend to create a NEW scope with a bigger range of addresses as its easier to manage that multiple scopes.
At work we've had a similar problem but we tend to work with /22 address ranges split between 2 servers with a /23 range on each i.e
10.100.0.1 -> 10.100.3.254 - having half the allocation on each server.
Not sure what range you have, but use this as an opportunity to consider future growth and maybe migrate whatever you have to a bigger range. I'd go with deleting and recreating with a large available set.

You can try to change the lease time in DHCP to 8 hours.
I agree with jimmyray7 and woolnoir, the best way is to recreate a new, bigger scope of IP addresses, although creating a new, additional scope is also a possibility, depending on how many workstations you have currently and planned expansion of the network.
If you want to change network mask in scope, you have to delete it and create once again. So, I would suggest to create new scope and configure New Superscope by selecting both of them. Then you don't have to reconfiguring your existing scope or delete it and create from the beginning.
Isiek has a point too. Its about personal preference both methods have their merits.

Thanks for all the suggestions!! I am looking at the properties of the scope....can't I just change the end ipaddress to extend the ip addresses? My scope has the ipaddresses stopping at .150, so I am thinking I could just change that to .175 and give myself another 25 ipaddresses.

As a general rule btw ( as previous experts have commented on ) its always a good ideal to have a relatively low lease time - a lot of people pick 7 days which for an office environment is pretty silly. It depends on your occupancy levels, but if you have a significant section of your workforce who arent working every day, then pick something like 24 hours for a lease, that way a 50% occupancy means 50% IP allocation on average, rather than closer to 100% if you use 7 days.
I know im going off topic a bit, but re-do your lease together with some tweaking as i and other posters have suggested should help you loads.
