I have a DHCP server role set up on Domain Controller (OS: Windows 2012 R2).
I have an enlarged scope /23. (x.x.236.0 --> x.x.236.1-x.x.237.254
I am getting a ton of errors saying the there are no available IPs when I show only 51% in use and assuming there are static IPs set in the network, I ran a scan and show only 175 addresses in use.
Total Available Addresses: 286
In use (DHCP): 146 (reserved or leases)
Sample Error Msg: "DHCP client request from MAC*****C4F0 was dropped since the applicable IP address ranges in scope/superscope "The Scope" are out of available IP addresses. This could be because of IP address ranges of a policy being out of available IP addresses."
I do have a Scope policy to assign specific Mac Addresses to an IP Range - 60 unit pool and only 49 MAC addresses to date.
