I get this error in the system event log on every node in my domain.  "The IP address lease 0.0.0.0 for the Network Card with network address 00A0C972BCC1 has been denied by the DHCP server xxx.xxx.xxx.xxx (The DHCP Server sent a DHCPNACK message)."  Please help! Sometimes the IP address listed is a valid IP in my subnet, other times its just 0's.

Can you post more info?  Where are the DHCP licenses coming from?  What OS on the client?  Is the DHCP server on the same subnet as the nodes in question?

Maybe you have another DHCP server in our LAN not properly configured. This second server could send the DHCPNACK messages.

Make sure the any power saving features on the NICs are disabled.

Reset the hubs/switches servicing the nodes in question as well.

Rogue dhcp server. Run MS' tools to identify all servers, and unplug the bad-boy.  If really down and in a hurry, just unplug some groups of stations, see if that fixes, to identify/isolate the culprit.

> has been denied by the DHCP server xxx.xxx.xxx.xxx

Possibly this identifies BadBoy?

> with network address 00A0C972BCC1

At various times, NICs or Mobo's are delivered with identical addresses. There are upgrades an patches to fix the supported ones. If the system used to work, then no issue, but if these were all newly networked together, then it is worth checking out.

0.0.0.0 is in the range?  You pulling a dynamic IP?
