If a Windows 2000 system with the Release Candidate 1 DHCP client attempts to get a DHCP lease from a Network Registrar DHCP server, it will be unsuccessful. The Network Registrar DHCP server logs the following error:

Server name/dhcp/1: 0 Unable to find necessary Client information in Inform packet from MAC address: '1,6,00:00:00:00:00:00'. Packet dropped!

Network Registrar includes error checking specifically designed to deal with errors in the DHCP client, such as this improperly built FQDN option. However, if you encounter this problem, install the Microsoft patch to the RC1 client on the DHCP client. You must obtain this patch from Microsoft.
