Thanks Michael,<br />

Have you ever come to the wrong conclusion after failing to look at all the information available to you? &nbsp;I did just that with this server. &nbsp;In fact, the leases were simply available. &nbsp;<br />

My kid is currently studying Spanish. &nbsp;Yo estoy stupido. &nbsp;I think that's correct.<br />

Anyway, thanks. &nbsp;Your kind comments

Thanks Michael,

Have you ever come to the wrong conclusion after failing to look at all the information available to you?  I did just that with this server.  In fact, the leases were simply available.  

My kid is currently studying Spanish.  Yo estoy stupido.  I think that's correct.

Anyway, thanks.  Your kind comments

I'm running out of dynamic IPs in DHCP on my Win 2003 Server.  I just noticed, however, that the my leases stop at 10.20.2.160 even though my scope goes all the way up to 10.20.2.254.  I've looked and looked for a setting that's constraining my leases to 10.20.2.160, but I can't find it.  It's worth noting that DHCP is integrated with dynamic DNS.  I haven't found anything there either.

Windows Server 2003, DHCP - Unutilized Addresses

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).

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
