DHCP May Not Assign a Default Gateway to Windows NT Clients

• Microsoft Windows NT Server versions 3.5, 3.51, 4.0

SYMPTOMS

If you have configured a domain host configuration protocol (DHCP) server to provide a default gateway by using DHCP option 003 (router), Windows NT DHCP clients on the network receive a valid DHCP lease and all other DHCP lease options except the default gateway.

CAUSE

The DHCP option 003 (router) option was configured with a value that is not on the local subnet.

RESOLUTION

To resolve this problem, configure a valid value for this option. The default gateway for any computer running IP must be on that computer's local subnet.

STATUS

This behavior is by design.

MORE INFORMATION

Client computers running Windows 95 will accept an invalid default gateway and place it in the route table. Windows NT clients check the value they receive; if it is not on the local subnet, they will disregard the value.
