| Event Id | 1020 |
| Source | DhcpServer |
| Description | Scope, 10.1.1.0, is 100 percent full with only 0 IP addresses remaining. |
| Event Information | In Windows 2000, leases that are expired but fall within the grace period appear in Microsoft Management Console (MMC) as inactive leases. Statistically, they are counted with active and excluded leases as "In Use." However, any lease that falls within the grace period (inactive) may be issued by the DHCP server if the available leases fall to 0.This behavior may become apparent if you are using short lease times and short scavenge intervals. The DHCP snap-in in MMC may display Scope Full icons (with an exclamation point on the Scope and Server icons) and the event log may contain event ID 1020. These notifications are based on the number of "In Use" addresses and occur even though inactive leases may be available to be distributed to requesting clients. |
