Thanks guys, the server was not authorized, but how could that happen? &nbsp;Just a few hours ago, it was working fine. &nbsp;What would cause it to deauthorize?

I am running windows server 2003 R2, and as of 15 minutes ago, I have computers that are not getting IP addresses from my DHCP server. &nbsp;The IP addresses they get is: 169.254.228.x<br />

How do I fix this? &nbsp;I have plenty of IP address, about 50%. &nbsp;I tried ipconfig /release and renew, but nothing, same thing happens.

DHCP server not handing out IPs

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).

DHCP

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
