Hello, I i have DC installed on win 2008 R2, and i did a new installation ( windows 2012 R2 ) and move DC to the new server, i did backup DHCP from the old server and restore it to the new one with " dhcp server export\import command " everything is working fine, but DHCP IPV4 is showing that scopes is full ( i have more than 30 scopes ), i checked every scope but all of them have free IPs. i checked DHCP from server manager and there is a warning message about IPV6. I unchecked IPV6 from network card properties.
I have 1 primary domain controller and 2 aditional domain controller. i did move one adititional DC this week and got the same issue with it, today i moved the primary DC and have the same DHCP issue. both DHCPs are working fine and assign IPs.
Regards,
