DHCP Address State is active even when the lease has expired

Question

DHCP Address State is active even when the lease has expired

Ekta Babbar 1

For some reason, the DHCP address state stays active even when the address lease has expired.

The expired leases don't show up in the DHCP Management Console, but when I run a powershell script to get the active leases, all the expired leases are still there with the address state as Active.

Any suggestions on how to fix this?

Hello,

Have you checked the configuration of the DHCP server, scope, and database? Is there anything unusual?

Check the DHCP server event log to see whether there is associated with the lease expired or address assignment errors or warning messages.

Hi,

I did not notice anything unusual under DHCP configuration. DHCP logs show that Database cleanup began, but it didn't see any expired IPs " 24,03/25/24,Database Cleanup Begin,,,,,0,6,,,,,,,,,0"

I exported a list of DHCP server leases using PowerShell, and this is what I see:

The lease AddressState is Active, even when it has passed the Expiry Time.

Is this normal?

Hi,

I did not see anything unusual in the DHCP configuration. The DHCP server logs say that, DHCP database cleanup began, but no expired leases found, "24,03/25/24,Database Cleanup Begin,,,,,0,6,,,,,,,,,0".

I also see some DNS Update Failed errors.

When I export a list of leases for a specific scope using powershell, this is what I see:

The lease addressstate shows as Active, even when it is past the LeaseExpiry time.

Is this normal?
