DHCP Server Does Not Provide Options to Remote Boot Clients (183199)

SYMPTOMS

Your diskless workstations (or other devices), that use Dynamic Host Configuration Protocol (DHCP) to obtain IP address information and BOOTP file and server information, may not obtain the DHCP options that are configured in the client's DHCP reservation.

CAUSE

Some DHCP clients do not request any option parameters in their DHCPDISCOVER packet or their DHCPREQUEST packet. Windows NT DHCP server expects the client to request the necessary options in either the DHCPDISCOVER or the DHCPREQUEST packet. Windows NT DHCP server will not provide any option parameters unless specifically requested by the client.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.5, 3.51, and 4.0. We are researching this problem and will post additional information here in the Microsoft Knowledge Base as it becomes available.
