DHCP Lease Expired -- Windows 2003

My DHCP server still shows the attached leases, but they are already expired (past the 10hr period)

In the past I looked at this I was thinking it did NOT show already expired leases.

I rebooted the server, RESTARTED the DHCP service, etc,
but the expired leases are still displaying instead of going away.

 1. Do expired leases stay until someone else uses the IP address ?
 2. Is my DHCP server maybe failing to DROP these expired leases now ?

The below will happen if I don't
have all my IPs used, correct ?
  ** 6:02 am = lease expired
  ** 10:02 am = server is READY to release IP if needed NOW
  ** 11:00 am = hourly cleanup releases IP if not already done (could be changed if desired)

My DHCP server has HKLocalMachine\System\CurrentControlSet\Services\DHCPServer\Parameters\, but no LeaseExtension under that.  It does have DatabaseCleanupInterval = 60 (decimal) --> 3c (hexadecimal)

I assume this is OK and LeaseExtension was just never created in Windows 2003 ?
