Event ID: 1007 Source: DHCP

Your computer has automatically configured the IP address for the Network Card with network address <MAC address>. The IP address being used is <ip address within the range>.
As per Microsoft: "The failure of the DHCP server to respond could be caused by network connectivity issues, DHCP server or DHCP relay malfunction, firewall issues, or a malfunction of your computer's network interface card or driver". See MSW2KDB for details.

See "IBM Support Document id: MIGR-58745" for additional information about this event.
When no DHCP server can be contacted it can also use the "Alternate Configuration". This is a user configured address instead of the automatic generated IP-address in the range. The same event is generated.
I got this after configuring the DHCP server but forgetting to authorize it in Active Directory.
See ME244268 and ME255836 for information on how to troubleshoot this problem.
Message generated when a computer is configured to obtain its IP address automatically (from a DHCP server) but no DCHP server answered the request. A random IP address (within the range) is assigned to the computer. Check the availability of a DHCP server for that segment.
