how to add new DHCP SCOPE with existing active DHCP SCOPE
I have DHCP Scope 192.168.0.1-192.168.0.254. I am getting event ID 1020 notification "Scope, 192.168.0.0, is 92 percent full with only 10 IP addresses remaining."
We use DHCP/DNS on single domain controller. How do i add new scope/subnet 192.168.1.1-192.168.1.254 linked with existing scope 192.168.0.1-192.168.0.254? ?
Please Let me know.

Please Let me know.
are 192.168.0.x and 192.168.1.x the same network in your environment? basically you need to check your network mask, if it is 255.255.255.0, then they are not in the same network and you may get connection problems if you add the 192.168.1.x in your DHCP scope.
Hey
Here's a couple more on extending and expanding your scope:

Hi
OK .. You can expand your network address space using the following:
IP Address : 192.168.0.0
Subnet Mask : /23 (or 255.255.254.0)
IP address range : 192.168.0.0 - 192.168.1.255
Network ID : 192.168.0.0
Network Broadcast : 192.168.1.255
Host IP address range: 192.168.0.1 - 192.168.1.254
Here is a link that goes through the example:

How does that sound?

Yes 192.168.0.x and 192.168.1.x are in the same network in your environment. My subnet is 255.255.255.0 with one default gateway 192.168.0.254 (Firewall)
if your mask is /24 (255.255.255.0), how can 192.168.0.x and 192.168.1.0 in the same network?
Hey ..
Did you mean that you'd like them on the same network. If so, you need to change your subnet mask to /23.
Make sense?

Hi
Just checkin' in. How goes it on the quest for more IP address space. Were you able to get anything working?

I belive I must change subnet 255.255.255.254. thne only i will get ip rqange 192.168.0.0 and 192.168.1.0
I have two domain controllers (DC1 primay n DC2 backup) with assigned dhcp, dns,wins on same domains (DC1 and DC2).
At present i have 192.168.0.0/255.255.255.0. .Where do i need to change new subnet 255.255.255.254?
I think i need to take following actions
-change new subnet mask in network property ip address in both DC
-create new DHCP scope with start IP 192.168.0.1 to 192.168.1.255 with subnet 255.255.255.254
Am i right? IF no, please suggest me steps. Also let me know Do i need to change anything with WINDS/DNS?? My default gateway is 192.168.0.254

sorry I must change /23 = 255.255.254.0 = 2 Class C networks = 2 x 256 = 512 IP addresses..
But i don't know the steps n action plan. pl. let me know.

Hi
If you have a primary and back domain controller, they both have the same subnet mask information in them. So with the change you made to the last post, the /23 255.255.254.0 needs to be in each. You may need to check your documentation on the order of the change.
Now, this change shouldn't require any down time. I would suspect that the WINS information stays the same for this.
If anyone else is listening in on this, perhaps flyingsky, it would be nice for swatujct to have a second opinion on this.
Hope this all helps and I'll try and keep a close eye on it.

Do i need to create new DHCP scope with start IP 192.168.0.1 to 192.168.1.255 with subnet 255.255.255.254 in DHCP?? Do i need to change anything in DNS Configuration???
Yes. You need to change the IP address range and subnet mask. No, you do not need to change DNS. How is your DNS configured right now?

I have 2 dns servers 192.168.0.9 and 192.168.0.11
