In Windows System Event log, there are DHCP server warnings that IP address range of a scope (10.40.0.0) that available is low.

But in the DHCP program, the Address Leases is only showing 4 or 5 leases. Based on the settings it should allow 235 leases in total.

There is only 4 for reservation. enter image description here

Is it the Windows System Event log warning is inaccurate? Or is it the DHCP program's Address Leases inaccurate? How do I resolve this to see accurate information?

This is in a Windows Server 2012 R2.

    Please check network mask for that DHCP scope. Nov 15 '21 at 11:01
  • Hi @ZoranJankov are you referring to check the Subnet mask? I added a screenshot of the Subnet mask, what should I check in there? Nov 18 '21 at 11:19
  • Hi @Boon Chye Phang! Yes I was referring to the subnet mask. I thought you accidentally put wrong subnet mask, but it is fine. What about your address reservations? Check if you have any. They will count as leased addresses. Nov 18 '21 at 11:26
  • Hi @ZoranJankov, I have checked there is only 4 IPs for reservation. Added the screenshot of it too. Nov 19 '21 at 4:48

Is it the Windows System Event log warning is inaccurate?

No the event log is accurate. 27 days ago on October 21 that was the status of the DHCP scope available leases.

  • Hi Greg, the screenshots of the DHCP address lease was also taken around the time, that is why I cannot understand why the lease is only a few. Do you have any idea why? Nov 19 '21 at 4:52
