Hey all,
Two 2019 servers. Both domain controllers, with dhcp/dns etc. Failover in Hot Standby mode.
Attempting to connect a pc to one of our scopes it wasn't being given an IP address. Errors on DC:
Error 20287 DHCP client request from B0C090A4835A was dropped since the applicable IP address ranges in scope/superscope Civic - IT are out of available IP addresses. This could be because of IP address ranges of a policy being out of available IP addresses.
Details for scope:
192. 168.66.1 to 192.168.66.254
Excluded 192.168.66.1 to 100
Excluded 192.168.66.250 to 254
No reservations.
There are 24 leases on the main and 3 leases listed on the failover. Statistics show 142 of 149 ip's in use!
Can anyone explain the discrepancy between the statistics?
thanks
