Are the machines not powered on at the time, or in sleep mode? That is when I notice reservations shown as inactive.

I had thought that too but the system I am currently working on was showing as inactive as well. &nbsp;It didn't show as active again until I did an ipconfig /renew

We have a DHCP scope setup with an exlusion range to match the range for distribution.  We are doing this so that users are unable to put random systems on the network without our knowledge.  We have reservations setup for all of the systems.  Once we set the clients to acquire an IP address automatically, the Lease Expiration column displayed 'Reservation (active)'.  However, later on during the day the column displayed 'Reservation (inactive)' for quite a few of the systems, to include mine.  I have the lease expiration in the scope set for 7 days.  If the clients are within their lease date range, why are they showing as inactive?

Why are active DHCP leases showing as Reservation (inactive)?

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).
