I have a windows 2012 server, running DHCP service, with MAC whitelisting (the &quot;Allow&quot; list)<br />
<br />
whitelist functions correctly, unauthorized MAC are ignored<br />
<br />
logging is fine I can see it in windows\system32\dhcp,<br />

DHCP requests from MAC not on whitelist, they get ignored, but Im *not* seeing a log entry documenting these unauthorized MAC address dhcp requests.<br />

is there some switch/setting to log these?

Windows Server 2012, DHCP with MAC whitelist, unauthorized MAC not appearing in log

I have a windows 2012 server, running DHCP service, with MAC whitelisting (the &quot;Allow&quot; list)

whitelist functions correctly, unauthorized MAC are ignored

logging is fine I can see it in windows\system32\dhcp,

is there some switch/setting to log these?

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).
