DHCP Clients are sending the DHCP Discover but our DHCP server is not responding. Verified this by running Network monitor to capture packets. This is occuring on not one but two DHCP servers both of which are having identical problems. We have completely reloaded NT Server on one of the machines and experiencing the same problem. Verified that DHCP relay agent is not running. We feel we have covered all possible troubleshooting techniques to include re-installing DHCP. All to no avail. Any suggestions or links to a source of help would be greatly appreciated.
