Hi
I have two DHCP servers running on domain controllers on Windows Server 2012 R2. There is only one IPv4 scope and it set up in failover mode on the two servers. I want to delete a lease in order to convert it to a reservation with a different IP address, but deleting the lease doesn't have any effect. Refreshing the view shows the lease is back. I've deleted the lease on both servers and replicated the scope, but no effect.
I also tried the powershell commands, but results are the same. It is also not an isolated case, as I've since tried deleting different leases, but it doesn't work. There are no messages in the event log to indicate any problems.
Any ideas?
