We are a Windows 2008 domain environment.
Our dhcp range is 192.168.1.50 to 192.168.1.200 subnet mask of 255.255.255.0
We have basically run out of ip addresses
We changed our subnet mask to 255.255.252.0 which now gave us almost 750 more ip addresses.
We then changed our dhcpk scope to 192.168.0.20 to 192.168.0.240.
After rebooting Windows 7 client the computer did not receive an address.
After an ipconfig /release and renew it received a new address.
After rebooting the clients lose the address again.
Tried multiple clients with same result.
Removed scope and recreated the original scope still using the new subnet mask abd everything works fine.
Is there something needed if dhcp server is 192.168.1.20 but giving out addresses on 192.168.0.x
All the ip addresses fall within the subnet mask.
Any thoughts are appreciated
